The document discusses 5 types of computers: microcomputers, mini computers, mainframe computers, super computers, and personal computers. It provides details about each type, including examples and typical uses. Microcomputers are the smallest and can be used by one person. Mini computers are more powerful than microcomputers and are used for tasks like CAD. Mainframe computers are the largest and most powerful, used for complex calculations. Super computers are the fastest and most expensive, used for scientific tasks. Personal computers are for general home use by a single user.

4. Information about Micro computer’s.
Micro computer’s are the smallest digital
computers. These computers have a Monitor,
Keyboard, Floppy drive, Mouse and hard disk
drive(HDD).They can be used by one person at a
time. IBM PCs, Intel 80286, 386, 486, Apple
Macintosh, Intel Pentium II,III, IV, Laptops, etc are a
few example’s of micro computers.

5. Information about Mini computers.
A mini computer is a medium-sized computer which is more
costly and more powerful than a micro computer. An important
distinction between a mini and micro computer is that a mini
computer usually designed to serve multiple uses simultaneously. Mini
computers are popularly data processing systems among the business
organizations today . They have large random access memory(RAM)
and high storage capacity. Normally, this size is developed to handle
specific task like CAD calculations and engineering. PPD-II, magnumeic
VAX 7500, etc are some examples for mini computers.

6. Information about mainframe computers.
Mainframe computers are large and general purpose computers.
Mainframe computers are larger and more powerful than micro
computers and mini computers. They are used to solve complex and
lengthy calculations. These computers can support a large number of
hardware devices. A mainframe is the heart of a network of computers
or terminals which allows hundreds of people to work at the same time
and on same data. Mostly, we find them in big organizations like Banks,
Industries etc.., These computers are expensive and more powerful,
CYBER 170. CDC 6600, IBM 4318 etc are the examples of mainframe
computers.

7. Information about super computers.
Super computers are largest, fastest and more powerful
computers. They are at least 100 times faster than any other
computer. They are expensive and occupy large space. They are
used to perform complex scientific jobs. They do billions of typical
calculations within seconds. Some examples of super computers
are param 10,000 , Cray xmp-24, nec500 etc. Anurag and param
are the two super computers developed in India.
Note: Whole over the world the super computers are only 300. In India there only 2
super computers among those 300 and in America approximately 200 computers
are there.

8. Information about personal computers(PC’s).
The computers that are used for general purposes at
home are called personal computers. PC’s are designed for
general use. They are usually used by a single user. PC’s
were earlier known as micro computers. Desktop
computers, Laptops. Tablet pc are the examples of personal
computers.
