About

Computers are machines that function on data based on the list of instructions. Early electronic computer systems consume much power. Modern computer systems, on the other hands, are based on small integrated circuits. Today, basic computer systems can be produced to match in a watch and driven by watch electric batteries.

Generally, a computer has four main sections like the ALU or the arithmetic and logic unit, the memory, the control unit and the IO or the input and output devices. The basic insight and output, control device, register and control units are known as the Processor or central digesting unit. Early central processing units had been constructed of numerous circuits but today it can be typically constructed on a solitary integrated signal known as a microprocessor.

The Arithmetic or Logic Device (ALU) is capable of executing two modules of operation such as logic and
