D2-Justify the considerations for selection in the upgrade of an exsiting computer system.

To answer this question i am going to use one of the computers i picked in the previous task. I have chosen to use the computer i chose for my previous task.

One thing you could upgrade on this compputer is to upgrade the CPU. You could get a quad processor CPU. This would benefit the user of the computer as you will be able to run more applications and programmes; the applications and programmes you run, will run a lot more quicker than before. Also, you will be able to run programmes like inkscape and adobe illustrator and it would not crash more than before you upgraded the CPU.

Another thing you could do to upgrade the computer is to upgrade the graphics card. If you upgrade the graphics card, you would get one that had more video memory and a faster GPU. When looking for a graphics card, you need to look for certain things. Looking to check it is suitable with your motherboard; so looking to check whether it is a PCIexpress or a PCI graphics card. Then looking at the video memory of it. A graphics card has special memory that is dedicated to the graphics that is done on the computer. Then finally you need to look at the GPU. If the GPU has more cores on; which usually have hundreds, unlike a CPU which usually has 2, 4 or 8; but are a lot bigger. If the GPU has more cores on, then it will run quicker and the speed of the game, drawing application etc will run a lot quicker and would be less likely to crash or have errors.
Another thing you can upgrade is the RAM of the computer. The more RAM the computer has, the more applications you can run at the same time. When you run applications on your computer, it has to take it from the hard drive and place it in to the RAM. So if you don't have a lot of RAM, the processor may have to re-write them back onto the hardrive for a short while, which take time; as it takes longer to write applications to the hardrive from the RAM rather than from the hardrive to the RAM. Upgrading the RAM is connected to upgrading the CPU. If you have a good CPU with more cores then it will run better and the more RAM you have, the more applications you can run and the CPU can process them quicker and easier than if you have less cores or a smaller RAM.
One other thing you could upgrade is the hard disk. When upgrading the hard disk, you want to upgrade to one that has more memory to store more applications and files; and also one that is faster. An average hard disk runs at 7000RPM (revolutions per minute), so you could upgrade and get a hard disk that runs at 10,000RPM. When you upgrade your hard disk, looking for one with more memory is essential. This is because you can then store more files and applications on your computer and even programmes. This would benefit the user as they could use more programmes or even different ones. Having more memory space free on the hardisk will keep the computer running at a good speed. This is because when the hard disk starts getting fuller then the computer will start slowing down whilst running etc. So upgrading the hard disk so that it had more memory would mean that the computer would not run slower.
