A general-purpose computer has four main components: the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by buses, often made of groups of wires. Inside each of these parts are thousands to trillions of small electrical circuits which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a “1”, and when off it represents a “0” (in positive logic representation). The circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits.
Input devices
When unprocessed data is sent to the computer with the help of input devices, the data is processed and sent to output devices. The input devices may be hand-operated or automated. The act of processing is mainly regulated by the CPU. Some examples of input devices are:

Note
There are two kinds of computer memory: primary and secondary. Primary
memory is accessible directly by the Central Processing Unit. RAM is an example
of primary memory. You will know more about RAM later in this lesson. As soon
as the computer is switched off, the primary memory loses its contents. But data
can be stored and retrieved at much faster rate with primary memory as compared
to secondary memory. Examples of secondary memory storage devices are floppy
disk, magnetic disk, hard disk, CD, pen drive etc. The secondary memory devices
may be inside or located outside the computer. Primary memory is more expensive
than secondary memory.
When the computer is doing any task, the data that have to be processed are stored
in the primary memory. This data may come from an input device like keyboard or
from a secondary storage device like a hard disk. As program or the set of
instructions is kept in primary memory, the computer is able to follow them
instantly. For example, when you book ticket from railway reservation counter,
the computer has to follow some steps, viz., take the request, check the availability
of seats, calculate fare, wait for money to be paid, save the reservation and print
the ticket. The program containing these steps is kept in primary memory of the
computer.
But inside the computer, the steps followed are quite different from what we see
on the monitor or screen. In computer’s memory both programs and data are
stored in the binary form. You have already been introduced with decimal number
system that is the numbers 0 to 9. The binary system has only two digits, 0 and 1.
These are called bits. A bit is an acronym for binary digit, which stands for one
binary piece of information. As human beings we all understand decimal system
but the computer can only understand binary system. Consider that a computer
consists of numerous switches. If a switch is ON then it is considered as 1
otherwise it is considered as 0. A number of switches in different states will give
you a message like this: 110101……10. So the computer takes input in the form of
0 and 1 and gives output in the same form, i.e., 0 and 1 only. But we do not receive
