4. 1. Types of Computers
1. Micro Computers:
The smallest among them are micro computers.
They are small in physical size (most of them are desktop
system)
They are economical in terms of costs and are friendly in use.
Personal computers (PCs) fall into this category. 4

5. 1. Types of Computers
1. Micro Computers:
These computers can be used for small data processing jobs
of bigger companies or serve as complete computer systems
for small firms.
PC can also be connected with bigger computers and be
used as an intelligent terminal to a bigger computer.

1. Micro Computers:
Workstation:
Workstations are mobile computers, stationary towers, or
rackmount systems that are specifically designed and
configured to meet the most demanding professional
workloads and workflows.
These types of computers are configured to meet power
users’ technical computing requirements, including high
performance, data integrity, reliability, and manageability. 7

2. Mini computers:
Mini computers are very popular among medium sized
companies. Mini computers offer facilities for faster processing
of voluminous information. Mini computers, of course, are
bigger than microcomputers but smaller than most of their
elders called mainframes.
The mini computers like AS/400 series from IBM have been
quite popular in computer aided manufacturing, as well as
departmental computers. 9

3. Mainframes:
Mainframes are bigger computers, capable of handling data
processing needs of, say, head office of a bank, or a big
multinational company or may be a public utility office.
Mainframe computer systems have larger storage and the
speed of processing is also very high.

3. Mainframes:
They offer features such as parallel processing. The parallel
processing that break down an application into many separate
parts in order to enhance processing speed.
The speed of processing is expressed in terms of 10 to 100
millions of instructions per second (MIPS). IBM still holds
almost 80 per cent of mainframe market with its popular
mainframe series IBM System 390.

4. Supercomputers:
Supercomputers have a speed of between 100 to 900 MIPS.
They are quite expensive and cost somewhere around 10-30
million dollars depending upon the configuration.
Supercomputers are designed to work in areas that need to
process large amounts of data in a short time.
In addition to studying the climate, the supercomputer is used
in the study of oceans, astronomy and biology.

4. Supercomputers:
It also allows the study of atoms, as it is used in quantum
physics experiments, weather forecasting, climate research
(such as global warming), representation of chemical and
biological molecules, as well as in biology and pharmacology,
which studies the structure of proteins and enzymatic
reactions that are the basis for the pharmaceutical industry.
