Comparison between different types of digital computers
Presented by: Umesh Duwal

2. Warm up
The computer we are using at our home is called ______ computer.
Go to www.menti.com and use the code 34 67 1

3. Warm up
Classify computers on the basis of
data handling.
Go to www.menti.com and
use the code 34 67 1

8. Differentiate between Supercomputer and mainframe computer
S.NO SUPERCOMPUTER MAINFRAME COMPUTER
1.
Super computers are used for large and
complex mathematical computations.
While Mainframe computers are used as a storage for
large database and serve as a maximum number of
users simultaneously.
2.
Supercomputer’s speed is more than
Mainframe computer. It can execute billions of
instructions within a second.
Mainframe computer’s speed is comparatively less
than Supercomputers. In this millions of instructions
are executed simultaneously.
3. Supercomputers are the largest computers.
Mainframe computers smaller than supercomputer in
size.

9. 4.
Supercomputers are the most
costly in the worlds.
Mainframe computers are less
costly than supercomputers.
5.
In the present, the
supercomputers have Linux
and their variants operating
systems.
While Mainframe computers can
have multiple operating systems
simultaneously.
6.
Super computers are mostly
purpose-built for one or a few
specific institutional tasks.
Mainframe computers are built to
handle a large variety of tasks.
7.
Seymour Cray invent the
Supercomputer.
The first successful mainframe
computer is invented by IBM.

10. Warm up
The computer we are using at our home is called ______ computer.
Go to www.menti.com and use the code 69 26 54
Differentiate between Supercomputer and mainframe computer

11. Differentiate between mainframe and minicomputer
S.N
O
MAINFRAME MINICOMPUTER
1.
In mainframe computer, large
size of disk is used.
While in minicomputer, small size
of disk is used.
2.
Mainframe computers have
large memory storage.
While minicomputers have small
or less memory storage than
mainframe computer.
3.
The processing speed of
mainframe computer is faster
than minicomputer.
While the processing speed of
minicomputer is slower than
mainframe computer.

12. Mainframe computer is
costlier than
minicomputers.
Whereas
minicomputers’s cost is
less or it is inexpensive.
Mainframe computers
support thousand or
millions of users
simultaneously.
Whereas
minicomputers support
hundreds of users at a
time.

13. Differentiate between microcomputer and minicomputer
Microcomputer Minicomputer
A microcomputer is a standard
desktop computer used at a
home and in business.
Minicomputers are mid-sized
computer used in universities,
research labs and small corporations.
A microcomputer is a computer
with a microprocessor as its CPU.
Minicomputers are faster than
microcomputers.
They are cheap, compact and can
be easily accommodated on a
study table.
They are expensive and larger than
Microcomputer.

14. Microcomputer is a single-user
computer.
Minicomputer is a multi-user
computer.
The two most common types of
storage devices used with
microcomputers are tapes and
disks.
For secondary storage, most
minicomputers use magnetic disks
or tapes.
Microcomputer is not powerful
or as fast as minicomputer
Minicomputer is powerful than
microcomputer but not as super
computer and mainframe computer.
Examples are- Modern computers
like desktop, laptop etc.
Examples are- IBM 9375,
Motorola 68040 etc.
