Computers are available in
different shapes, sizes and weights, due to these different shapes and sizes
they perform different sorts of jobs from one another.
They can also be classified in
different ways. All the computers are designed by the qualified computer
architectures that design these machines as their requirements.
The four classification of
computers
- Micro-Computer
- Mini-Computer
- Mainframe Computer
- Super-Computer
- Microprocessor
There are many computers which
are different from each other in various aspects. Classification of computers
are given below :
a) Micro computers: These
computers use a microprocessor chip and this chip is used instead of CPU means
that this microprocessor chip works as a CPU.
These computers are also called
personal computers. Two major types of these computers are laptop or Desktop
computers. Only one user uses these computers at time that's why they are also
known as personal computers.
Example :
b) Mini Computers: These are
powerful computer. These computers come into existence in 1960s at that time
mainframe computer was very costly. Mini computers were available in cheap
prices, so users start using it.
Example :
c) Mainframe Computer: It as a
very powerful and large computer. You can get idea of its power as it can
handle processing of many users at a time.
Terminals are used to connect a
user to this computer and users submit there task through mainframe. Terminal
is a device which has keyboard and a screen. By using terminal users put inputs
into the computer and get the output through screen.
Example :
d) Super Computers: As the name
"super computer" specifies that these are most powerful computers
even than mainframe. Actually, when we optimize a mainframe computer then we
get super computer.
Example :
e) Microprocessor: You will find
these computers everywhere. Microprocessor chips are used in many devices as
I-pod, DVD, headphone etc.
Example :
