Why is a computer so slow, even after first buying it? There are hardly any software titles on it but it is still slow……what more when you put more software titles on it.
When you first buy a computer from a shop it will be Fast,What makes a computer slow?…..even when it is brand new. Articles because you were sold a computer with the bare minimum only installed on it – Windows Vista and Microsoft Works (or Microsoft Office) for example. It is not heavily installed with Updated Security files (Security Updates) and Patches (Fixed/Improved/Updated Windows Vista files and program files) because the shop cannot do this. Once you have bought a computer you have to be the one to register Windows Vista with Microsoft and therefore it is you who has to install any additional Security Updates and Patches for that computer and Windows Vista. For example. If it took the shop 2 Months to sell the computer that means the computer is already 2 months behind with the updates – Many new security updates, virus updates and program updates would have been released in this time. And maybe some software updates for the computer’s hardware as well. All these updates are required to keep the computer up-to-date, and more importantly Windows Vista up-to-date and protected against attack from Viruses, Hackers and so on. What this means is without the updates you have a fast, but vulnerable (open to attack), computer. With the updates the computer becomes slower and slower due to Windows Vista being given more security tasks (jobs) to do, which means more memory and resources are required, which in turn means the hardware might become slower (more modem/internet data coming down the telephone line, for example, means more data that has to be translated/organised).
PROTECTION AND MONITORING MEANS SLOWER AND SLOWER
You install an Anti-Virus program to protect the computer from Viruses (files that are, normally, downloaded onto your hard drive and then launched to damage certain files). You then install a program to block Pop-up windows (Windows that appear suddenly without your consent. Usually with Advertisements on them). You then install a program to stop Hackers (people who try and steal information from your computer via an Internet connection). And finally, you install a program to stop SpyWare (software that monitors/collects information about your activities on the computer). Unfortunately, in todays age, these four types of program are needed to protect the computer. If you do not install them the computer’s security is at risk and if you do install them the computer uses up more memory and other resources, as well as having more tasks to do. This is because each program is constantly monitoring the computer for attacks. The information they need about the different kinds of attack are usually stored inside a file that has to be updated regularly and checked against in order to prevent/stop a specific kind of attack. When an attack has been identified the protection program still has to monitor for other potential attacks whilst taking care of the identified attack. And if a window tries to pop-up the pop-up blocker program has to destroy that window before it has chance to appear. All this monitoring is slowing the computer down.
The same applies to the Internet. It becomes slow when you have ten website pages open, as opposed to one website page open, because Internet Explorer is having to do ten tasks instead of one. Those tasks include saving history files (see The Hard Drive section) for each website, checking to see if you are still connected to the internet, managing uploads/downloads to/from each website and so on.
FOREVER GROWING UPDATE FILES
An anti-virus program uses a Virus Definition file, which is a list of all known viruses to the present day and instructions on how to identify and remove them. As a new virus is unleashed it is given a name and its Identify And Remove instructions are added to the virus definition file. When the anti-virus program starts it copies the identify and remove instructions from the virus definition file into memory, so it can quickly identify and remove a known virus. Memory is faster than a File at feeding the CPU instructions, so it is ideal for the anti-virus program to use memory. The downside of this is that anti-virus programs, and other programs that need updated files, use a lot of memory and other resources in order to protect the computer. This ultimately means a slower computer.
TOO MANY PROGRAMS INSTALLED
Having too many, unwanted/unneeded/unused, program
