Computer Basics

Who says that accessories are only for people? Nowadays, you can also give your computer an attitude through the use of computer accessories. More than just as eye candy, these computer accessories are also guaranteed to help your computer experience become much better than usual. Computer accessories are also gaining ground as a popular commodity because of the many benefits people find about them. You will be surprised with how many computer accessories are now made available to the public. From children to adults, computer accessories have definitely reached the peak of its popularity.

The Uses of Computer Accessories

Perhaps the most popular among the various computer accessories are mouse pads. Most people might even mistake them to be part of the hardware but they are not. Mouse pads are important because they provide your mouse with a smoother surface to run through. Imagine if you have to simply let your mouse go over the table, it’s surface will end up scratched and so will your own table.

Although computers have their own internal speakers, it usually just emit warning sounds or even errors. If you needed to hear something of an audio file or through the internet, you will need external speakers to facilitate this for you. Music lovers who constantly find themselves in front of the computer even purchase booster speakers these days for a musical pleasure trip.

Speaking of being constantly in front of the computer, most desktops nowadays can be seen with screen protectors over them. Aside from protecting the monitor’s screen from scratches, these computer accessories also act as a shield for the user’s eyes. Being in front of the computer for too long will really hurt the eye specially under glaring screen conditions. Through screen protectors, computer accessories find themselves functioning for the benefit of the users as well.

Where to Purchase the Best Computer Accessories

One of the best venues for purchasing computer accessories are computer wholesale shops. You can easily find cheap accessories for sale in there. You can also purchase online although it might be a bit hard if there are certain specs which must be followed so that these computer accessories will fit into your computer. You can also try visiting the electronics sections inside malls and even electronic shops because they also sell various computer accessories.

Just keep in mind that you need to buy computer accessories which you know how to use. Do not buy one if you are uncertain of its functions because it might end up damaging your computer system. Plus, be sure to follow setup instructions carefully so that you don’t end up harming your computer in the process. Have someone help you out in setting up your computer accessories if you are fidgety about the thought of doing it all on your own. In addition, you should also ask for warranty cards especially if you are buying computer accessories which are a bit costly. This will give you some peace of mind that should there be problems, you can have it in exchange of something much better.

Marshall has been running as a way to present various computer accessories in a new way.

So you've bought your computer and want to get online? It's not as simple as connect the wire and off you go these day's. The internet is a weird and wonderful place as long as you can control what you do.

That's why you need to protect yourself. These can be done in a number of very simple steps. This article will get you started but you should always try to be smart when your surfing the net!

Step 1: Anti-Virus Scanner

Whether you're connecting to the internet or not, you need an Anti-Virus scanner. Your computer can become infected with "viruses". These are little files or codes that have been written to ruin your computer! That's why they must be stopped!

There are many programs out there that can help, but it's best to trust only the mainstream programs as these are used widely and updated regularly.

Step 2: Firewall

Ok so your thinking what is a "firewall" sounds scary right? Well it's not really. It is again another line of defence against the number of ways your computer can be attacked. In simple terms it blocks other computers and programs from connecting to you and playing with your stuff. Think of it as an internet wall of fire, where you allow what can pass through.

Software - Again there are many programs available to protect you, Recent Microsoft Windows machines come with Windows Firewall, which can be described as basic at best. We do recommend you go for mainstream again.

Hardware - A firewall can also be included as part of your hardware, like an internet router "that's the box that sits between your pc and the internet line". This is the best and recommended way to have a firewall. As it blocks intruders before it gets to your pc.

Recommendations:
Zone Alarm

Step 3: Be AWARE!!

Simply put watch what you download and accept to save to your PC, sometimes people can send you files in e-mails. They look ok but when you run them they will install something onto your PC and leave you upset and distraught. Always scan something that has been downloaded before opening it and never open/run programs that have been sent in an e-mail from unknown sources.
Step 4: Go for it

That's pretty much it to get you going. If you think something doesn't look right, it probably isn't. Hopefully this will get you going to start with, wait till you find out about spy ware and Trojan's!! Good Luck and Safe Surfing

Many people want to have some kind of spy equipment for better home security. However, besides wireless spy cameras, VCR or DVR systems, there is also special software used to control those surveillance gadgets.

Large companies use professional security systems along with already built in (embedded digital video recorder or PC based DVR soft) spy camera control software. But what about smaller guys? Do you also have to spend thousands of dollars for professional spy security system and software to feel safe and secure in your house? And the answer is not necessarily.

Webcam for Spying Purposes

You have the ability to use your webcam (connected to your PC) as a surveillance tool. And to control it, all you need is inexpensive webcam surveillance software. As a matter of fact, such software allows you to connect more than one camera. It can display as much as 16 webcam views on your computer screen.

Moreover, webcam surveillance software even allows you to detect motion and start capturing an event within milliseconds. This means that you don't have to keep your webcam surveillance software turned on all the time in order to secure the area. By using motion detection webcams, you can also save your computer's HDD (hard drive) space.

You know, video takes a lot of hard drive space. Non stop recording for 24 hours can cost you 1GB of HDD space a day. Well, it depends on the chosen image quality. Lower quality images will require less bandwidth. Also, if you set lower FPS (frames per second), then you'll save even more HDD space.

But if you have a large HDD (like 160GB or more), then there's nothing to worry about.

What to Look for in Webcam Surveillance Software?

Before you decide to order webcam surveillance software, there are a couple of things to consider. Let's take a look at some of the features of webcam software that you should seriously consider, ok.


Audio Capturing - Does your webcam surveillance software have audio capturing option? If not, then you should consider that carefully. If you want to record a conversation, it's crucial.

Compressed Files - Does your webcam software compress video files? If not, then the space of your HDD might fill up quickly. Try to search for software that compresses the video without losing its quality.

Remote Access - This is very important. If you leave your webcam to record the area, you should have the ability to access your webcam's view via internet connection. This is very neat function that is absolutely must in webcam software.

Motion Detection - We've already mentioned that. Motion detection is also extremely important. You don't want to record the area when nothing's going on, right. So make sure that motion sensing is enabled in your software.

Alert Options - Does the webcam surveillance software have an alert option? Some webcam software alert when they detect something. They can alert via email or even dial a phone number. You should seek for this feature, because it's very neat.

Multiple Webcams - Can your surveillance software record a live view from multiple web cameras? 2, 4 or 16? If you want to connect more than one camera to your PC, then multiple webcam support is absolutely must in the software you choose.
Stealth Mode - Does the webcam software run in stealth mode? Stealth mode means that nobody can see if the software is running or not. Not even if they Press "Ctr+Alt+Del" and look at Windows Task Manager!


Look for webcam surveillance software that allows you to do all or at least most of the functions mentioned above. If your software isn't capable of detecting motion, doesn't have alert option, doesn't have audio recording options, then search for a better solution.

In Conclusion

Webcam software (for spying or home protection purposes) combined with a few inexpensive webcams, can definitely serve as a basic home security system. You can put your webcams in the most important places and have your PC to record each camera's view. And if motion sensors detect something unusual, they can alert you via email or phone.

However, if you're really looking for quality and all-in-one solution for professional home protection, then a more powerful DVR security system with multiple spy cameras could be your best shot. Such systems cost over thousand dollars, but they're ideal for quality home or office protection.

As we started the project of our web site, we knew that the proprietary software costs would be too high for our financial resources. Our only option then was to make use of Open Source Code softwares.

However, within the Open Source Code there are lots of softwares to choose from, and it´s up to the system analyst/programmer to pick the ones that best suit the project goals.

In our case, we picked Linux as our operating system. However we faced a big question: Which Linux distribution ? There are dozens of linux distributions, each one with specific advantages, sometimes with or without paid services.

We chose linux Slackware because we thought that it would suit better our needs, in terms of stability and reliability. Slackware is a conservative distribution, meaning that it only offers in its distribution package kernel versions and third party libraries, once it´s been proved to be stable and reliable. As a result, Slackware is one the most stable Linux operating system on the market. If the user wishes the most recent Linux kernel and libraries, we recommend to look for a different distribution.

Another reason for us picking Slackware, was because of its text interface, which at the beginning may become a bit difficult, in the long run however it offers a better understanding of the Linux environment. This way most of Slackware configurations are done thru text scripts.

Once it was set the operating system, we picked Apache as our web server. Apache is one of the most popular web server in the internet. For server programming language, we chose PHP. Also, a very popular programming language. Our experience with Apache/PHP proves that this setup is very reliable, working extremely well in our production environment. For workstation programming language, we chose javascript, which besides of having a simple syntax, it offers lots of resources.

Apache web server is really a complete web server. Also, it can become very complex with many configuration setups.

For our database, we picked Postgresql. This database has been made available to the public for more than 15 years, and besides of being well debugged, it offers so many resources that it has become one of the best database options from Open Source Code softwares. Extremely reliable, Postgresql has reported cases where there have been databases in production with over 4 terabytes. Besides all of that, Postresql is not the most popular Open Source Code database. A matter of marketing ? Probably.

As for the programming language PHP, we had to use an object oriented application structure. There are many PHP application structures being offered with Open Source Code license. Object oriented application is very important, because it makes programming very easy and scalable up to the point where the system may grow without many problems. Also, it helps to keep PHP code separated from HTML, with the help of some specific libraries, such as Smarty. We make use of Smarty library and we believe that it is a very important resource, which can even make web pages faster thru the use of its cache functions.

Also a very important set of libraries worth mentioning for PHP systems, is the PEAR libraries. In PEAR web site, among the many libraries being offered, there are the database interface DB and the MAIL_QUEUE, which sends emails thru the use of database.

As we came to the end of our project, we had to use some sort of real time database replication. For that we chose the DRBD and Heartbeat libraries. The use of database replication is very important and should not be postponed. Just after 3 months our system got into production, our server hard disk became bad. Thru the use of DRBD/Heartbeat we were able to put the system back into production within seconds, without loosing any data. DRBD/Heartbeat replication is done thru the use of a lan network between the server and slave nodes.

Our project also makes use of ImageMagick (enlarge and reduce images), Iptables (firewall), Tsearch2(text search in portgresql) and Mon (linux monitoring tasks).

Also a very important library worth mentioning is the pseudo APC compiler for PHP. Speed is always a critical factor for internet sites.

Our web site is already in production and based upon our experience we can say that the Open Source Code softwares we picked, proved to be extremely reliable and stable. Open Source Code softwares can certainly be an excellent option for developing web sites.

A year ago if someone asked me if I knew my way around the CRM Software Industry I would have confidently said yes, however, as it turns out the old saying the more you learn the more knowledge you realize you lack, is true. When talking about the CRM Software Industry it is almost impossible to actually say that you know it inside out since there are so many CRM vendors around the world, all developing their technologies at such a rapid pace. As if it wasn't hard enough for a company to make a decision regarding; what they require, how it can help their business and so on, these technological advancements are always followed with a marketing campaign each speaking of how much this new feature or functionality will help you.

So the question stands at, you think you know CRM Software? This is difficult to answer with all the hype surrounding the industry combined with the relative youth of Web-based CRM and the large number of vendors. It is also difficult to produce a linear comparison since each vendor has their own set of terms and names for features. So where do you begin? You can learn the basics of Web-based CRM Software fairly easily with a quick search on Google, however I would like to mention a few points that are more difficult to uncover; the hidden costs associated with purchasing CRM Software, what to avoid, how your CRM can go beyond simply contact management and where the industry is going.

When a company decides it's time to make the move to Web-based CRM Software they should first develop a plan on how they expect this new implementation to boost their companies productivity and revenue. The largest roadblock in achieving a fast ROI is all the hidden costs that are not clearly listed on vendor's web sites. In researching to develop a comparison of some of the major players in the CRM world including Salesforce, Netsuite and Salesboom.com, the majority of my time was spent researching pricing for different platforms, upgrades, implementation, customization and customer support. Salesboom was actually the only one at the time to have a page with their pricing listed clearly.

To just go out and purchase a CRM Edition and think you are done is nowhere near the truth, this is just a base point from which pricing begins. This leads me into what to avoid when seeking your future CRM Software. What you need to look into and ask questions about is; storage limits and the cost of additional storage, maximum number of custom tabs & fields, maximum number of applications you can add, this being particularly relevant for Salesforce, and any other limitation which could later force you to upgrade.

If you have implemented a CRM Software Solution and reached any of these mentioned limitations I'm sure you can vouch for my statement that it comes at a great cost. What is often the case is that the edition a company is currently working with is doing a great job but for example they have reached their storage limits. An edition upgrade for a company with roughly 750 users can amount to around 2 million dollars above what they were already paying. With this upgrade of course comes more features and functionality however they are features and functionality which will not increase your ROI simply because your company doesn't need them.

Now that the buyers beware and the negatives are out of the way we can focus on the positives. When you implement your new Web-based CRM you have just knocked down all the walls separating your departments or office's, no matter their location and you did it in real-time. Once up and running your CRM goes far beyond contact management software with vendor's now integrating front and back office functionality. Netsuite has a strong back office, which makes sense knowing their background in back office ERP solutions; however I find their SFA or front office not to be up to the standards of some others. Salesforce and Salesboom.com both offer a well rounded CRM solution for companies of all sizes, between these two it really comes down to price.

With more than just contact management capabilities CRM Software is a great tool for your; marketing department with in depth campaign and lead management tools, your customer service department since a complete history of all clients and cases are a mouse click away, your back office including inventory, billing & invoicing by taking advantage of real time workflow processes and of course your sales force with features like escalation rules or in more recent times offline and mobile editions.

Today CRM Software vendors are coming out with Offline and Mobile Editions giving new ways to never lose contact with the office. This brings us to the future of Web-based CRM Software, where is it going? Well over the past year we have seen great advancements with the use of AJAX, or as it's known to the tech world, Asynchronous JavaScript and XML. This code underneath your CRM Software eliminates the need for you to refresh your web browser whenever you make a change. This can be seen in some social networking sites, a popular one being facebook. Here AJAX is used to allow for drag and drop customizations to appearance and the arrangement of applications. The idea is the same with CRM Software, a simple down mouse click and drag will allow you to customize the appearance of your dashboard without an IT department, so you can focus on the information most relevant to you.

The other benefit that AJAX will bring us in the future when combined with faster internet speed is the elimination of load time, maybe not completely but at least the majority of it. This sort of functionality is now only seen with On-premise software since all information is stored within your computer or server you don't need to wait for the internet to download any data. AJAX comes into play here since you don't require a browser refresh you can continue working while only that portion of the web page is reloaded. I predict that the gap between Web-based and On-premise CRM Software will be much smaller by the end of 2008 and we will see the same trend with businesses leaving their On-premise for Web-based CRM, like was seen in 2007.

Internet worms.
Is your PC infected?
If your computer has become infected with a worm, don’t panic, it is not the end of the world.
There are a number of things that you can do.
Microsoft has a security web page.www.microsoft.com/security/default.mspx It offers up to the minute information on the latest security threats and worms. It also provides you with all of the tools to dig out the worms and fix any damage that they may have caused.
I expect that most of you are saying that you already have protection. May I ask a question? “Is it up-to-date?”
We all know that virus protection is essential. The trouble is that a lot of us have not updated our virus protection software since we purchased our computer, possibly three or four years ago.
The chances are, it is completely useless against the latest threats.
I am using AGV anti virus. I have found it to be totally reliable. There are other programs, I expect, that are just as good. Zone alarm also has a very good reputation. There are lots of others that won't break the bank.
Go to Google and type in “anti virus programs” and you will get more results than you could shake a stick at.
You only need one of these programs on your computer at one time. More than one and they tend to get confused and anything could happen.
Whatever program you use, be sure to keep it up-to-date. There are new viruses coming out almost on a daily basis. Try to get an update at least once a week. It’s always better to be safe than sorry.
A lot of programs will email you when a new virus appears and offer the appropriate update as part of their service.
Whatever you do, don’t leave it until tomorrow. Tomorrow may be too late.
Do it now and sleep easy. Viruses have been known to cause nightmares.
All the best. Bob…

The good news about computer repair technician jobs is that technology is always changing and will require highly skilled people to provide support and service. The bad news is that the IT department is a high cost administrative area that is a slow moving target for budget cuts.
Most IT departments expand or contact based on the projects and technology desired or even required by any given company. There are very good times and very bad times for most computer repair technicians. I know, I’ve been in the Computer Repair business both as a contractor, self-employed or even as a fulltime employee for over 30 years.
The best way to deal with these up and downs in available work is to have a solid fall back plan that allows you to prosper in either situation. Computer Repair is a huge market in both commercial and individual areas.
Computers break, software confuses and disorients many people. That’s a fact. Although the user interfaces are becoming more friendly, the technology necessary to make them work is getting more and more complex. Throw in the Wild West style of the Internet and you have a perfect scenario for someone with the proper skills to make money full or part time.
But where most “techies” get into trouble is in both the day-to-day business requirements and selling and marketing their services. People skills are also important when running your own company. If you watch any movie about computers and software, and the folks who really understand them, they paint a pretty sad picture of the individuals involved.
It’s not quite that bad, but there are many facets that are true. Large IT departments often have an attitude that they are smart and everyone else is dumb. This type of environment is not a good training ground for the self-employed. In fact, it’s not a good thing for anyone, the department or the clients they serve.
Never the less, that less than good attitude is there and predominate. I was fortunate early on in my career to have a mentor who truly understood the fact that the only reason the IT department exists is to serve the rest of the company. Many IT folks never get that salient fact.
The successful computer repair business owner must know how to sell and market their services to both individuals and small business owners. They should also have some good people skills, because every computer has an operator. And many of the common computer repairs have to do with the individual between the chair and the keyboard.
Doing freelance computer repair work can be very profitable on both a part or full time basis. You’re selling knowledge and time for the most part. Sometimes hardware is involved but over half the service calls have to do with software, configuration, and problem solving.
So no matter what the computer repair technician jobs situation is, you can supplement or even replace your income by selling your self. The tax benefits alone can be a huge advantage. Being somewhat of a geek myself, I love being able to buy the high tech toys and getting to take a deduction since most items directly apply to my job.
So with the addition of a few new skills (business marketing and people), any computer repair technician can make some good money part or fulltime. So what kind of money is possible doing computer repair work?
Well, lets say you want to start out slow and just make some extra money for a great vacation, new toy, or college tuition for the kids. If you just do about 10-12 hours of part time work a month, only charge minimal amount ($50 an hour instead of the going $75), you can make an extra $7200 a year.
Maybe you save another $2-$4K in taxes, which gives you another $1,000 cash. So that’s quite a little jolt to the household budget for whatever. And if you should get a pink slip, for whatever reason, you could even crank up the part-time business to help fill the gap.
Of course the trick is acquiring those new skills. That’s where I might be able to help you out. Like I mentioned earlier, I’ve been in the computer repair business for a long time. During those fun filled years I’ve developed both marketing and business practices directly related to the computer repair business.
I’ve compiled all the information into one big package that teaches and provides many marketing and business operating tools. Everything from a basic website, to software, and even marketing materials. This is not some general business guide. Every piece of information, every software tool, and marketing piece applies to a computer repair business.
And all of the material has proven to be successful in own computer repair business. There is no theory here, just proven successful methods I use everyday. If you want ot find out more, click on the link below.
So if you are looking for computer repair technician jobs, you might want to consider hiring yourself. I don’t know of any other business that you can start for less money or has a larger target audience.

Most of us rely on our personal computers and those in our office to complete multiple tasks each day. If that data is lost or compromised it can create numerous problems for us. Protecting computers against viruses and spyware is something you should do before you start using any program on it. The information you prevent from being accessed could be your credit card accounts and bank accounts. If they are compromised you can end up becoming a victim of identity theft.
One way that people accidentally end up with viruses or spyware on their computer is by not paying attention to the sites they use. Don’t get into the habit of giving out your personal information online just because a site asks for it. To opt in, you should only have to give them a first name and an email address.
Always check the address in the URL to make sure you are accessing a secure site. It should start with “https” as this will let you know it is very secure. If it only starts with “http” then the site is not secure and you can end up compromising the security of your computer if you continue entering information on the site.
Viruses can spread very rapidly so if you think your computer may be infected, you should take care not to pass it to any other area of your computer or to others via email. By disconnecting your computer from the network you have a good chance of isolating the damages.
Always be on the alert for various types of emails known as phishing. This is a scam to get you to provide personal information. Once you do, spyware can be attached to your computer. Never respond to emails asking you for personal information as most credible companies won’t contact you for such information.
Make sure you purchase a virus and spyware protection program that is very easy to install. Most of them offer step by step instructions for you to follow. You can find out how easy such software programs are to install before you buy them just by reading some independent reviews online.
You need to choose the program for your computer protection very carefully. While they are designed to give you the very best security, you can be sure those trying to pass viruses or get spyware into your system are very smart. They have learned elaborate tricks to be able to gain access to your information.
One of the latest tactics that these criminals have been using is to sell software that is supposed to protect your computer from viruses and spyware. Unfortunately, what they are selling you is actually the very thing you are trying to protect yourself against. Always get such software from a company that has an excellent reputation, not just any one that you come across online for a good price.
In order to ensure your computer is well protected against viruses and spyware, you want a program that offers you instant updates. These will usually happen for one full year after you install the program. This ensures that your protective software is always the most current available and criminals will have a hard time infecting your computer system with viruses or spyware.

Are you ready to purchase a new computer? Great! The choices can be daunting, though. Just looking at the price aspect, you can spend anywhere from three hundred euros to several thousand euros, quite easily.
The first choice you'll need to make is whether to buy a desktop or a laptop. If you need any amount of mobility at all, we'd suggest a laptop. If you don't plan on moving your computer around or using away from your home or office, you might want a desktop. Desktop computers are easier to repair and are cheaper for what you get.
Next, you'll need to make a choice on some of the major features and components of the computer.
Memory is a big factor in determining how quickly your computer performs tasks - I would not buy a computer with less than 512 MB of memory. 1 GB of memory would be even better. If you are planning on doing lots of multimedia work or other tasks that require a lot of operating resources, you should probably get 2 GB of memory. Also keep in mind that memory is classified by speed as well as storage size.
You'll also need to decide on what processor you want and/or need. If you're not familiar with the technical aspects of computer processors and you are going to need a processor that's more powerful than standard, you might want to consult with a computer expert to help you make the choice.
You'll also need to choose the hard drive size you'll need. This is any easy choice to make - just see how much hard drive space you're using now, add in any increases you expect to need, then add some space for expansion.
There are many, many different components of a computer that you'll have to choose. It's worth a little time to think about exactly what you need so you make the right choice the first time.

What is a computer?
Computer is an electronic device with a ability to: -
1. Accept data 2. Input, Store and execute instruction. 3. Perform mathematical and logical operation 4. Output results according to users requirement
Computer has certain Limitation:-
1. Cannot think on their own 2. Task has to be described in detail. 3. Do not learn from experience. 4. Cannot detect or correct errors in logic or data.
HISTORY OF THE COMPUTER : People have always needed to count. Earlier they counted with their fingers and probably through scratch making on trees or bones or on the walls of their caves. Over the centuries the science of numbers and computing has changed dramatically. People are now able to solve very sophisticated problems, and increasingly so with the aid of computers. Today we use computers in virtually every environment. From the executive in an office to the housewife and her washing machine to the teenager recording his/her favorite television programme, computers have entered into practically every sphere of human activity. The history of computing can be traced back to Abacus (2000 BC). Used primarily by merchants, the Abacus was a mechanical device used to add, subtract, multiply and divide numbers. Centuries later, mechanically operated devices were developed. These machines could add and subtract numbers (in 1642 Blaise Pascal's Calculating Machine), as well as multiply divide numbers (in 1671 Leibniz's Calculator) A few years later Charles Babbage, referred to as the "father of computers" devised a machine (Analytical Engine) which could be "programmed" by instructions coded initially on punched cards and then stored internally.
GENERATION OF COMPUTERS :
First Generation Computers - 1951-59 : They used vacuum Tubes as their principal component. They could store 10,000 to 20,000 characters. Magnetic Core Memory was used.
Second Generation Computers - 1959-64 : The Second Generation Computers replaced the Vacuum Tubes with Transistors. This led to the miniaturization of Computers. The concept of Multi Programming was introduced with Second Generation Computers. The most popular Second Generation Computer was the IBM 1401.
Third Generation Computers - 1964-70 : The Third Computers introduced integrated circuits, the equivalent of hundred and thousands of transistors on a small silicon chip. This drastically reduced the cost, size and power requirements. This technology produces powerful Mini Computers.
Fourth Generation Computers - 1970 till now The LSI (Large Size Integrated) Technology with many thousand of Electronic Devices on a small silicon chip signaled the Fourth Large Number of Character could be stored and also these Computers were much faster. IBM 370 was most popular machine.
A computer system can be viewed as a system of three Major Components:-
Hardware : It deals with a computer equipment that is mechanical, electrical, and electronic parts of the computer.
Software: It contains programs that instruct a computer how to process data and generate required information.
Human-ware : Person who operate the computer and also those who write the program i.e. - operator, programmers etc
CENTRAL PROCESSING UNIT :-
The heart of the computer is CPU It performs the various function with help of following components :-
1. RITHMETIC LOGICAL UNIT (ALU) :- Performs the actual calculations such as addition, multiplication, subtraction, and comparison like greater than lesser than, equal to, positive, negative or zero
2. MEMORY UNIT (MU) :- Memory unit or main storage unit holds data, instruction (that are being interpreted and executed, the results are ready for the output)
3. CONTROL UNIT (CU) :- The control unit co-ordinates the operation ofthe hardware. It also co-ordinate the flow and execution of data and instruction that are feed into the memory or main storage of CPU.
PERIPHERAL DEVICES
Peripheral devices can be classified as
1) INPUT DEVICES: - It allows feed the data into C.PU. (Computer) Examples of output devices are explained below: -
1) KEYBOARD - It is a important input device which is use every where. The keys are same as typewriter. They are classified as follows: -A) Alphabet Keys (A to Z). B) Numeric Key (0 to 9) C) Alphanumeric keys (!@#$% ~ &*) D) Function keys (Fl, F2, F3,..... F12) E) Arrow keys (Up arrow, Down arrow, Right arrow, Left arrow) F) Special keys (ENTER, TAB, CAPS LOCK, SHIFT, CTRL, ESC, ALT) 2) MOUSE - It is a device, which can easy to operate by one hand only.
It looks like a rat or mouse. It includes a three buttons & we can operate mouse through that buttons
2) OUTPUT DEVICES - The data, which we feed in computer through input device that data are displayed through, output device whenever called. Examples of output device as follows: -
1) Monitor (Screen of the computer)
2) Printer (DOT Matrix, Laser, etc.)
3) Backing Storage Devices :- Are those devices which can store data feed in by the use of input device. Some examples of backing storage devices are as below:-1) Hard Disk 2) Floppy Disk 3) Compact Disk (CD)
CLASSIFICATION OF COMPUTER
Computers can be classified on purpose, components and size
1.ANALOG COMPUTERS 2.DIGITAL COMPUTERS 3.HYBRID COMPUTERS
Analog Computers : Analog computers are computer that measures physical quantities (eg. Temperature, length, pressure, Whether reports etc...) and convert them to numeric values. It is used mainly for scientific & engineering purpose.
Digital Computers : Digital computers are used for mathematical operations such as (eg . addition ,subtraction, letters, symbols)
Hybrid Computers: The features of analog and digital computer are combined to create a hybrid computing system. The doctors to measure hearts beats SIZE mostly use hybrid computers –
All digital computer store numbers, letters and other characters in coded form. The code used to represent characters is the binary code - i.e. a code made up of binary digits or bits. Every character is represent by a string of "Os" and ""Is" - the only digits found in the binary numbering system. When data is types into a computer the keyboard convert each keystroke into a binary character code. This code is then transmitted to the computer, when the computer transmits the data to the - printer or the screen, or to the disk, each individual character is communicated in binary code. It is then converted back to the specific character while displaying or printing the data.
One 'Bit1 is a short of Binary Digit. A collection of 8 bits is known as a BYTE and half of byte i.e. a collection of 4 bits is known as a NIBBLE; 1 Byte= 8 Bits; 1 Kilobyte (KB)= 1024 Bytes; 1 Megabyte (MB)= 1024 KB; 1 Gigabyte (GB)= 1024 MB.
Note :- Every character you type occupies 1 byte, Every Space occupies 2 bytes and every Enter you hit occupies 2 bytes.
TYPES OF STORAGE SYSTEM
1. INTERNAL STORAGE :-
RAM :- (Random Access Memory ).Where programs arid data are held during processing temporarily. Data stored in the RAM is lost when either the machine is switched off. ROM :- (Read Only Memory). Where permanent instructions or data are held. The ROM does not require a continuous supply of power to retain it contents.
2. EXTERNAL STORAGE:-
(A) HARD DISK : Hard disks are a collection of/ pack of diskettes, known as platters, made of aluminum, with their surface being coated with iron oxide joined together to form a cylinder. They have more storage capacity and speed than floppy disks.
(B) Floppies are made of Mylar plastic coated with magnetic oxide. The flexible material is cut into circular pieces.5 1/4" or 3 1/2" in diameter. They are called Floppy disk"

The past six weeks have been instrumental in teaching me patience. Normally, I'm a very patient person, but every once in a while an event raises its head and says, "Hold still, son, you have a lot to learn about patience and the wonderful things that could happen when you learn the secret of waiting."
Now, I must let you know that patience has not always been my strong point. In the days of my youth, I have been known to make quite a fuss when things did not move with the speed I wanted or expected.
Much as I have overcome most of the impulse to rant and rave when things don't get done as promised, I still have vestiges of hidden pockets of impatience somewhere deep within me.
My office runs through the proper use of computers and their associated systems. Sometime over the last several weeks, my main computer ceased functioning and the manufacturer promised to fix it. What started out as a simple matter evolved into an extremely complex situation.
Every day, I spoke with the computer company and they promised that the repair would be done within days. About two weeks into the frustration, I was told that the replacement part could not be found and so they would have to give me a brand new machine. Naturally, I was delighted that I would now get a replacement with all the bells and whistles.
The promise was that within a week, the new machine would be shipped. When a week came and went without the computer arriving, I found my frustration level rising to uncommon heights. Strange visions of writing a thousand letters to the manufacturer's corporate executives, or bashing the ailing computer with a baseball (or cricket) bat at high noon, with local and national press coverage crossed my mind.
I remembered, only too well, that an old, wise man had said that the last test of the master was overcoming impatience. But I was in no mood for masters or overcomings. The bumper sticker I saw on a car long ago described my deepest feelings. The sticker pictured a vulture sitting on a branch of a dead tree, sweat pouring from his head. The caption read: "Patience, my ass, I want to kill somebody".
I thought of the bumper sticker and smiled. Since I had been waiting for over two weeks, one or two more days won't make much difference. But the urge to take drastic measures came back in a few days when no new computer arrived.
Many times, in a rush to get from here to there or to do this or that, we make ourselves prisoners of time. Being a prisoner of time could be as terrible as being a prisoner in a dungeon. We make ourselves prisoners of time when all we do is rush to work, or rush here and rush there. We miss so much in life by rushing.
Somehow, the world passes us by, during our rushing and we wake up five, ten, or twenty years later and wonder where all the time has gone. Our children have grown up, our old jobs no longer exist, some of our friends have gone to another dimension and yet, the sun still rises.
If we were to slow our pace a bit and flow with the river of life, perhaps the problem would work out fine anyway. I have discovered that it is counter productive to force things to happen. It is much better to create a climate where we allow the things we want to occur.
With that in mind, I decided to let go of my attachment to outcomes. I was not going to fume and fret if my new computer did not arrive as promised. After all, I had been using my backup machines for a few weeks without undue hardship. What difference would another week or two make, anyway?
With those thoughts, I went about doing my work. Then, a few days later, I received an email which said that my new computer was being shipped the next day. All the proper specifications for the computer were in the email. The computer would be a brand new machine with the exact specifications of the old one. I was pleased -- very, very pleased.
But the next day, when I checked the tracking information, I saw that the shipment was canceled. ARRGH!! The vision of the vulture on the bumper sticker returned with a vengeance, but I gently pushed it away. The computer will come when it comes I murmured, and I went on with other pressing matters. I didn't even bother to call the manufacturer. I had done all I could do. Anything more would have just made me more frustrated.
Yes, the world does speak to us in thunder tones of truth. Listen and learn and life becomes more peaceful and joyous. Ignore the voice and frustration takes over. And so it was that the next day, I checked the tracking information again, not with the thought of getting my computer quickly, but just out of curiosity.
Imagine my surprise when I saw that my computer was shipped, but instead of sending an exact duplicate of the broken model, the company shipped me their most advanced machine that had just been released to the market a few days earlier. I would have waited a few months, if necessary, for that model. It was much more advanced than the old model I should have received. When the machine arrived, I smiled and said, "Thank you", to no one in particular.
Perhaps, it was releasing the constraint of time from my consciousness that precipitated this outcome. The universe speaks to us in many ways. Many times, like impatient children, we want what we want and we want it now. But the universe has a way of saying, "I know what you want, my child, and I know that you want it now. But if you would wait just a little while longer, I will give you something much better than what you think you want."
Strive to become free from the hustle and bustle of daily living. Release yourself from being a prisoner of time. In doing so, you'll find that things have a magical way of working themselves out and that where there's a "good" there's a "better". And where there's a "better", there's a "best". The universe wants you to have the best. Give it an opportunity to bring your "better" or "best".

With development in technology, broadband internet connections provide faster access. However, slow internet connection has become a major problem. The speed of internet connection depends on numerous factors. Hampering any of these factors can result in slow internet connection. Though some causes of slow internet connection cannot be controlled, most of the problems can be taken care off. Some tips for fast internet connections are discussed below.
1. Scan for malware and spyware: Spyware and malware are one of the major causes for slow internet speed. The first tip for fast internet is to scan your computer for spyware and malware and then delete them if they are found. These get downloaded on your computer along with some software or video that you download through internet. You must update your antivirus and anti-malware software quite often to detect and delete such harmful spyware and malware. There are many free and paid resources and programs to clean your pc of harmful threats. Take advantage of them.
2. Empty web cache: Next tip for fast internet is to empty your web cache or keep it as small as possible. Web cache contains temporary internet files that get downloaded when you visit any website or webpage. These files occupy huge disk space leading to slow computer speed as well as slow internet. Emptying it can speed up your computer as well as internet. You must delete all the cookies and history too from the cache. Cookies can be harmful if they are from malicious websites and can cause harm to your hard disk and invade your privacy.
A very useful feature on both firefox and internet explorer is the option to clear your cookies after each internet session. This can drastically speed up your web experience.
3. Increasing speed of web pages: One of the main reasons for slow internet connection is slow web page. They tend to be slow due to overload of animation and other scripts. The next tip for fast internet is to reduce the number of scripts and animation load on your web page. The fastest option is to restrict browser to display only text.
Another trick you can do to speed up the loading of web pages is to loadtext only browsers. This type of setting loads only the text and prevents the loading of any heavy graphics or animation, often the culprit of slow web browsing.
4. Use of proxy: A proxy server acts as a buffer between the internet resources that are being accessed and your computer. The servers save files that are frequently requested by numerous internet users in a special database which is called “cache”. Hence, proxy servers enable high internet and personal computer speed as they allow your computer to utilize this "cache of saved data". Your computer need not load the information or website that is sought to be accessed as it already exists on the server's hard drive. Setting up proxy server is very simple and can be done manually in 10 minutes.

I remember the first time I came across spyware on my computer and I was shocked at how much had accumulated and infiltrated my privacy without me even knowing about it.
My PC had been running slowly for a long time and was really beginning to frustrate me, At first I thought there must be some virus on it giving me some grief so I did the scans with more than one program just to make sure but it came up clean, I deleted all unwanted software and regularly ran the defragment program on my computer and it made very little long term difference so I thought it was just getting old and it was time for a new computer.
One time while I was surfing the Internet I stumbled across a term that I hadn’t heard before in regards to the computing industry and that was spyware. Due to my ignorance the first thought that came to mind is an image of agent 007 and it got my curiosity.
Obviously it had nothing to do with my initial thoughts but what I did find out was the answer to what had been causing havoc and causing my computer to run slow.
Spyware over time can cause your computer to run slowly and even be somewhat unstable and I thought that was bad enough but that wasn’t the worst of it, spyware is exactly what it says it is, It is tiny programs put on your computer without you knowing about it and they are spying on your activities and sending that information back to whoever owns the program and that information will be use for commercial use exploiting not only you but others.
Personally I think using spyware is an unethical way of obtaining information since the individuals have not given any permission for that information to be made somewhat public.
We all pretty much like to find out information about other people in a harmless kind of way, especially if we could possibly use it against them at some later date such as at their engagement party or wedding speeches, but it is all for a joke, gossip is interesting, isn’t it?
Where is the line between harmless and exploitation, this is really a personal opinion to each of us but since finding about spyware and what it can do I defend myself from the invasion.
Anti spyware programs have made it so much easier to get rid of these invaders because they are programmed to know exactly where to look for them because to us amateurs we would never find them, and that is how they were designed, so that we would never find them.
This practice is actually information theft, and may be unethical but at the moment it is not illegal because so far there is no way to regulate this kind of practice. If someone stole your car, most likely you would be pretty upset about it, do we tolerate people stealing information about us. To a certain degree we do but it is only because we don’t understand the implications of the theft.
I’m sure that when adware first came about it was innocent enough with the software programmers wanting people to experience the program and then make a donation or at least support them by viewing the sponsors advertisements, but maybe they weren’t getting enough and a better plan came along. Lets actually find out what they want by spying. I’m sure they could have just asked like the surveyors do but that requires manpower and a computer can do the same job.
Spyware places advertisements on your computer that pop up occasionally that are relevant to the things that you are interested in because it knows what your interests are now due to the information it has gathered about you through your internet browsing habits, the type of sites you visit, and the words you type in your searches.
So how do we remove spyware nuisances, It becomes a war between software programs since spyware is very hard to find for most people the only real way to get rid of it once it is on your computer is to get another software program that knows how to recognize spyware and remove it, fortunately this software is easily found and some of them will allow a free scan of your computer before you purchase.http://www.advantage-power.com/computing/how-to-remove-spyware.html
