The amount of times my friends have come to me asking about computers and what to and not to buy must suggest I know a little about computers, but why do I know so much......
I don't even remember the first time I used a computer, I have no idea, and I have no idea how I learnt everything i know now, part from a 2 year computing course at college :P. But yeah I though I would write up a quick guide to computers, you never though someone might find it useful.
The 4 Categories of Computers
Home - These computers will basically just be used for internet, mail and things like word, the basic home user need basically, these are the lower end of computers in terms of specs as well there not needed to be fast.
Business - These computers will be used by people who's work is mainly done on the computer, these computers are tbh essentially used the same as home, apart from more applications will be opened at any one time, so a slightly faster computer is preferred.
Gaming/video - These are the computers that have the widest range, and these are used for playing games and 3d modelling, video editing, etc, heavy thread tasks basically. Obviously computers like home and business can play games and what not, but too the same degree as these ones.
Extreme - These are the real deal in the computer world, now i bet you have heard of alienware right?? Computers along those lines are considered extreme computers, basically these computers will destroy anything they come across, including your wallet!!!!
Main Hardware for games
Processor - The brain of the computer, and thats about all people need to know, but when you see I5-760 2.96Ghz for example ( made the number up:P) do you know what the 2.96 Ghz means?
Well basically that number is how many instructions the core of the processor can do every second(although this actually isn't true when it come to mutli core processors but you don't need to know about that).
so say you have a 3.00Ghz processor, that means that processor will be doing 3,000,000,000 instructions every second....that's right 3 billion. Insane ain't it :P. There are loads more to do with processors but this will do for now.
RAM(random access memory) - the simplest way for me to explain RAM is it being like a motor way, and the instructions of the processors are cars, the cars have to travel through RAM(the motor way) to reach all the places they need to go. The more RAM you have, the more lanes on your motor way. "Ah ok thanks mike, so in my next computer I will get 16 GB's of RAM) NOOOOO!!! that would be a mistake, I wont explain why but if you are planning on buying a computer, you don't need more that 6GB's really 8GB's would be the maximum I suggest, Put it this way, if you had 8GB;s games wouldn't even touch it for at least a year if not more.
GPU - Just as I typed that i decided it would take too much time to explain really, but basic this thing makes all your images on the computer, plays your videos etc. In essence if you spent over £150 on one it would last you a while for gaming. The more money you spend the longer it will last. I think the latests GPU is 10 times as powerful as the PS3 or Xbox 360 by itself lol.
If you have read this and actually found it helpful and want to know even more just give me a shout. If you are thinking about buying a new computer or upgrading and not too sure what to get and would liek advise then give me a shout aswell if you want.
