Memory & ProcessorsThe processor is the most important component of a computer and can be virtually considered to be its brain. The processor or the central processing unit is more generally known as the CPU. As the term indicates, the CPU does all the computing in a computer. The CPU functions very much like the human brain and its construction is also similar.
Like the human brain with its network of nerves, the CPU works via a network of interconnected circuitry. It processes all information fed into it and carry out the necessary calculation. Manufacturers design different types of CPUs depending on the need. Like memory in the brain, a CPU can store information in specially designed ICs called memory.
