Q: What does CPU stand for and is it important?A: CPU stands for Central Processing Unit which is essentially the “brain” of your computer. These processing units translate commands and tell the other components what needs to happen in order for them to achieve the required task and without a functional CPU; a computer is unable to function.There are multiple variations and brands of CPUs, and the type of CPU contained in a computer dictates the types of tasks you are able to perform and how efficiently you are able to perform them. Those using their computers for general use would only need a single, dual or quad core CPU, for those that watch and edit digital media a quad or six core and avid gamers would benefit from a Core i5 or i7.
