The CPU or processor is the "brain" of the computer. It performs all the operations that the computer does, from the simple encoding of text to the complex rendering of video. So, the faster the speed of your processor, the faster your computer will run.RAM is second to the CPU in determining your computer's performance. It temporarily stores your computer's activities until they are transferred and stored permanently in your hard disk when you shut down or restart." RAM is measured in gigabytes (GB), and the average modern computer has between 4-8 GB of RAM. The more RAM your computer has, the faster it runs (up to a point). The hard disk drive, more commonly known as the hard drive or hard disk, is where all data and programs are stored in your computer permanently, unless you delete them. Generally speaking, a hard disk with a higher capacity is always better.
