TYPES OF COMPUTER
Supercomputers are the fastest computer and have
a large data storage capacity. A supercomputer can execute more than 100
million instruction per second.
It has multiple processors which are based on parallel processing
architecture for achieving high speed. It is made for some special purpose. It
can support more than 1000 users at a time. It is used for Space Research,
satellite management, Wheatear forecasting Aerodynamics, and complex
computation.
Ø First
Indian Super Computer “PARAM2000”.
Ø The
first supercomputer is CDC 6600 (designed by CDC Control Data Corporation in
USA).
Ø The
first five fastest supercomputer of the world are
1. Summit (US)
2. Sierra (US) ...
3. Sunway TaihuLight (China) ...
4. Tianhe-2 (China) ...
5. Frontera (US)
Ø Speed
of Supercomputer is measured in FLOPS.
Ø FLOPS (Floating
Point Operation per Second).
MAINFRAME COMPUTER
A mainframe is a very large in size computer which is
capable of supporting hundreds or even thousands of user simultaneously. It is
designed for specific purpose.
Mainframe systems are used in Banks, hospitals, railways,
educational institutions etc.
Examples: - IBM 4381, CDC cyber series, etc.
MINI COMPUTER
A
minicomputer supports the working of several user at a time. It has a larger
memory, high storage capacity & larger computing power than a
microcomputer.
It has
multiprocessing system and is capable of supporting upto 200 users
simultaneously.
Example:
HCL Magnum, VAX7500 etc.
It is
used in big Organization for Computer Aided Design, industrial application,
etc.
MICROCOMPUTER
A
microcomputer is meant for a personal computer. It is a small size computer
that has microprocessor chip as CPU. It is also called Desktop computer, PC,
computer etc.
It was
first developed by IBM (International Business Machines)
These
are common, economical and easy to use. Examples IBMPC100,200 Apple Macintosh.
Personal
Computers which are used at home, School and offices including desktops,
laptops and tablet PC.
It is
used for study, Entertainment, office works.
MOBILE
A
mobile is a hand held, portable & wireless telecom device. The prime
functionality of a mobile phone is to make Voice call, SMS and MMS.
With
the advancement of computing technology, such phones are called smartphone.
Console Game
Console
Game is a device that is primarily designed to play games with the help of
keyboard & joystick that is displayed on a TV or Monitor.
Ex-
Xbox, PlayStation series.
Embedded Computer
An
embedded computer is a combination of computer & other device that is
designed or made to serve a predefined or specific works.
Ex- ATM, Washing machine, Microwave Oven etc.
BASED ON WORKING:-
ANALOG COMPUTER
Analogue computers are designed
to process analogue data.
Analogue data is continuous data that changes continuously and cannot have
discrete values. We can say that analogue computers are used where we don't
need exact values always such as speed, temperature, pressure and current.
DIGITAL COMPUTER
Digital computer is designed to
perform calculations and logical operations at high speed. It accepts the raw
data as input in the form of digits or binary numbers (0 and 1) and processes
it with programs stored in its memory to produce the output. All modern
computers like laptops, desktops including smartphones that we use at home or
office are digital computers.
Hybrid computer has features of both analogue and digital computer. It is fast like an analogue computer and has memory and accuracy like digital computers. It can process both continuous and discrete data. It accepts analogue signals and convert them into digital form before processing. So, it is widely used in specialized applications where both analogue and digital data is processed. For example, a processor is used in petrol pumps that converts the measurements of fuel flow into quantity and price.
