1.1.1 Central Processing Unit (CPU)
It is the electronic circuitry of a computer that carries out the actual processing and is usually referred to as the brain of the computer. It is also commonly called 'processor' also. Physically, a CPU can be placed on one or more microchips called integrated circuits (IC). The ICs comprise semiconductor materials.
The CPU is given instructions and data through programs. The CPU then fetches the program and data from the memory and performs arithmetic and logical operations as per the given instructions and stores the result back to memory.
While processing, the CPU stores the data as well as instructions in its local memory, 'called' registers. Registers are part of the CPU chip and they are limited in size and number. Different registers are used for storing data, instructions or intermediate results.
