This document classifies computers based on their size from largest to smallest: Super computers are the largest and most powerful, used for scientific modeling and simulation. Mainframe computers are large servers that enable many users to access resources simultaneously, used by large organizations for tasks like ATM transactions. Mini computers have processing power between mainframes and personal computers. Workstations are used for engineering and design applications requiring moderate computing power and graphics. Personal computers are the smallest and most affordable for individual use.

2. LIST OF COMPUTERS
•Super Computer
•Mainframe Computer
•Mini Computer
•Work Station
•Personal Computer(PC)

3. SUPER
COMPUTER

4. SUPER COMPUTERS
These computers are the largest in
terms of size. They can occupy
anything from a few feet to
hundreds of feet. They also don’t
come cheap as they can be priced
between $200,000 to over $100
million

5. USES OF SUPERCOMPUTERS
• In the field of science, researchers use these machines
to compute and model properties of biological
compounds like protein and human blood. They are also
used to interpret new diseases and strains, and predict
illness behavior and treatment.
• The military use supercomputers to test new aircraft,
tanks, and a host of weaponry and camouflage. These
machines are also used to help encrypt and decrypt
sensitive data.
• Meteorologists use them to simulate weather behavior.
They can also be used to predict earthquakes.

6. MAINFRAME
COMPUTER

7. MAINFRAME COMPUTERS
•Mainframe computers are large and
powerful machines. However, they fall
short in terms of the computation ability
seen in supercomputers. They are like big
file servers, enabling multiple users from
nearby and remote locations to access
mainframe resources at the same time.

8. USES OF MAINFRAME COMPUTER
•These machines are used in large organizations
where thousands of clients have to access data
simultaneously.
•Examples include:
•Performing ATM cash withdrawals and deposits.
During the process, communication between the
mainframe and remote computer will help
accomplish the financial transactions at hand.

9. MINI COMPUTER

10. MINI COMPUTERS
•Minicomputers are general purpose
devices without the monumental
expenses associated with a larger
systems. Their processing power is
below that of mainframe systems but
above the capabilities of personal
computers.

11. WORK
STATION

12. WORKSTATION
•Workstation is a computer used for
engineering applications (CAD/CAM),
desktop publishing, software
development, and other such types of
applications which require a moderate
amount of computing power and
relatively high quality graphics

13. PERSONAL
COMPUTER(PC)

14. PERSONAL COMPUTER(PC)
•A PC can be defined as a small, relatively
inexpensive computer designed for an
individual user. PCs are based on the
microprocessor technology that enables
manufacturers to put an entire CPU on
one chip.
