Computer Basics

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

While not a new development, quantum computing is the next target for intrepid developers, most of whom are physicists and scientists rather than programmers and inventors. The hardware needed to run a quantum algorithm is finicky at best and is downright terrifying to maintain. But what is quantum computing and what goes into making a quantum computer?
Quantum What?
A conventional modern PC is capable of two binary states, these being a one or a zero. These bits make up all of the information that your stock home computer hold on its hard drive. However, a quantum computer is somewhat different. Rather than being able to operate in states of one or zero, it is able to be in both states at once or in superposition as well as every state in between.
Rather than binary bits, these machines use qubits. A quantum computer makes use of principles of quantum mechanics, notably quantum interference in the most widespread design models, rather than conventional physics in order to operate. Just to illustrate the difference in processing between your home PC and something quantum, a 30-qubit system will run at the real world equivalent of a conventional unit running at 10 teraflops. Since home users have got access to processing in the gigaflop range at the moment, this is a huge jump in power. Maybe Crysis will finally run on Ultra.
Does it Work?
It would appear that quantum computers are in fact a reality. They are very difficult to maintain, construct and understand. Unless you are one of the geniuses involved in the project, that is. Mostly theoretical at this point, there have been major advances in the field of quantum computing. In March 2000, scientists at the Los Alamos National Laboratory announced that they had constructed a 7-qubit quantum computer inside a drop a liquid. The liquid in question was either alanine (used to analyze quantum state decay) or the tongue busting trichloroethylene (used for quantum error correction) and the state of the qubits in question is read by nuclear magnetic resonance or NMR, which is a method of indirectly measuring the state of a qubit.
The problem with measuring a qubit directly is that an accurate reading will drop a qubit out of superposition (should it be in that state) and turn your quantum computer into a conventional one.
The methods used in quantum computing in order to create results are far too lengthy to fully explain almost everywhere outside their scientific literature and the systems being created also vary, making a broad assessment impossible. Very much in their infancy, there are strides forward being made. From 2000 and Los Alamos’s 7-qubit machine there have been; another 7-qubit machine demonstrated by IBM and Stanford University; the development of the first qubit using ion traps in 2005 and most recently a 16-qubit quantum computer that was demonstrated by D-Wave Systems in late 2007. Rather than just being a theoretical construct, this computer was able to solve Sudoku puzzles and other problems that were demonstrated.
Sooner than Expected?
D-Wave Systems in particular are raring to get a working model of a quantum computer on the market as soon as possible. Their planned system will not be a fully functional one but will rather be what one quantum algorithm designer calls ‘special purpose noisy piece of hardware’ that could take up the task of running physical simulations that are impossible on conventional silicon technology.
Looking forward to the future of computing quantum computing has the potential to far outstrip anything that a home user could have imagined. Such processing power could even be put to use creating a true life simulation, a form of virtual reality indistinguishable from reality itself.

Link building has kept search engine optimizers on their toes for some time now, and recent developments in they way Google calculates the relevance of links has made link building a complicated process. To understand how relevant link building works, it is important to understand why Google choose to implement the concept of relevant links.
When Google introduced the concept of PageRank, any website (with resources) could buy incoming links from websites that had high PageRank; this lead to an increase in proxy websites and single page sites. Such sites did nothing more than increase their PageRank, and sell outgoing links from their website. In addition, webmasters could easily purchase banner ads and outgoing links from websites that had nothing to do with their own website. In fact, the concept of PageRank was completely thrown out of gear as link building was reduced to nothing more than just a link isolation and purchase process. To ensure that link building was a sane and meaningful process, Google implemented an algorithm that took into account the quality of each outgoing and incoming link known as the relevant link algorithm.
In a nutshell, no matter how high the PageRank of the website providing the outgoing link the link will only add to the PageRank if it is deemed ‘relevant’ by Google. For example, a laptop website should ideally carry out link building by receiving incoming links from directories, computer websites, and other computer hardware companies. Even if the laptop website has an incoming link from a chocolate website or a used cars website, Google will (in all probability) neglect the incoming links. In fact, the reason why webmasters have started utilising the services of search engine optimizers for link building is to ensure that all links generated are relevant and permanent.
Another factor that has made relevant link building a complicated task is that Google has started penalising webmasters for buying links from websites. Contrary to popular belief, even if an incoming link is from a ‘relevant’ website but Google believes the only reason the link is present is because a webmaster has paid for it, the link will be noted as a paid link and will be disqualified. In fact, over a period of time the number of websites that have been penalised or have lost PageRank due to irrelevant or paid links has risen.
Webmasters that are planning to carry out link building should make sure they research all their link building options and make sure that all incoming links are from relevant websites. Since the Google paid links algorithm is still in its initial stage it is difficult to predict which paid link will be picked up by Google. In a nutshell, it is always a good idea to keep the Google paid links algorithm in mind while carrying out link building; and directories and content based websites are still the safest bet when it comes to link building.
