Types of computer on the basis of sizes: Mainframe Computer Super Computer Mini Computer Micro Computer Computers can be classified based on size into four main types: 1. Supercomputers – These are the most powerful and fastest computers, used for complex tasks like weather forecasting, scientific simulations, and cryptography. 2. Mainframe Computers – Large and powerful, mainframes handle massive data processing for banks, government agencies, and large enterprises. 3. Minicomputers – Also called mid-range computers, they are smaller than mainframes but still serve multiple users, often used in business and research. 4. Microcomputers – Also known as personal computers (PCs), these are the most common, including desktops, laptops, tablets, and smartphones. Each type serves different purposes, from high-performance computing to personal use.

forecasting.
• Nuclear simulations.
• Quantum mechanics simulations.
• Space exploration research.

8. MAINFRAME COMPUTERS

9. INTRODUCTION TO THE MAINFRAME
COMPUTERS
Mainframe computers are large and powerful systems that can
handle vast amounts of data and support many users
simultaneously. They are commonly used in industries like
banking, government, and airlines for large-scale transaction
processing and data management.

10. CHARACTERS OF MAINFRAME COMPUTERS:
LARGE-SCALE,
CENTRALIZED
PROCESSING.
HIGH
RELIABILITY
AND SECURITY.
SUPPORTS
THOUSANDS
OF USERS.
HANDLES
LARGE
AMOUNTS OF
DATA.
EXPENSIVE BUT
DURABLE.

11. ADVANTAGES:
High reliability and uptime.
Processes a large number of
transactions.
Supports virtualization and
multiple operating systems.
Suitable for large-scale businesses.
Highly secure.

12. DISADVANTAGES:
High cost of maintenance and
installation.
Complex setup.
Requires specialized staff.
Not flexible for small businesses.
Slow adoption of new
technologies.

13. USES OF MAINFRAME COMPUTERS:
• Banking and financial
services.
• Government operations.
• Airline reservations.
• Large-scale data processing.

14. MINI-COMPUTERS

15. INTRODUCTION TO THE MINICOMPUTERS
Minicomputers are mid-sized systems that are
smaller than mainframes but larger than
microcomputers. They can support multiple users
and are used in small to medium-sized businesses,
manufacturing, and academic institutions.

16. CHARACTERS OF
MINICOMPUTERS
• Mid-range power and
size.
• Supports multi-user
environments.
• Smaller than mainframes
but more powerful than
microcomputers.
• Affordable and versatile.
• Ideal for small to
medium-sized
businesses.

17. ADVANTAGES:
• Cost-effective.
• Easier to maintain than
mainframes.
• Suitable for multi-tasking.
• Lower power
consumption.
• Offers flexibility in
business environments.

18. DISADVANTAGES
• Limited processing power
compared to super and
mainframe computers.
• May not handle very large-
scale tasks.
• Not ideal for complex
simulations.
• Needs specific software.
• Less scalable.

19. USES OF MINI COMPUTERS
• Small business operations.
• Scientific research.
• Engineering and manufacturing.
• Process control systems.
• Educational institutions.

20. MICRO COMPUTERS

21. The first microcomputer
is Altiar 8800 was
commercially launched
as minicomputer but
because of its small size
and slow speed is was
classified into new
classification,
microcomputer.
WHY FURTHER
CLASSIFICATION OF
COMPUTER?

22. INTRODUCTION TO THE MICRO
COMPUTERS
Microcomputer are also known as personal
computer because of its small size and single
user based interface. It consist of a single
chip(CPU) which controls overall function of
computer system.

23. CHARACTERS:
• Affordable cost
• Single user based
interface
• Generate less
heat
• Can be used in
different
application fields

24. ADVANTAGES
• It is very affordable,
anyone can buy it
• It helps in designing
software and mobile apps
• It is very useful for
teaching learning
activities
• It allows us to compute
complex calculation
correctly

25. DISADVANTAGES
• It has slow computational power than other types of
computer.
• Due to the long usage, it may get addictive.
• Lack of security may cause in the harm of your
personal information.
• In the long run, the storage capacity may get
insufficient.

26. USES OF MICRO COMPUTERS
• Personal computing (word
processing, gaming, internet).
• Office work.
• Educational purposes.
• Small business management.
• Media and entertainment
production.

27. TYPES OF MICRO-COMPUTERS:
DESKTOP COMPUTER
This types of computer of different
components connected with a wire.
With its components its processes data
and display information
LAPTOP COMPUTER
Laptop computers are also known as
'Notebook' due to its small size and
briefcase structure . Unlike desktops, it
is highly portable.
TABLETS AND SMARTPHONES
They are the small handheld devices
that consist of touch display. It can also
performs the advance function like any
other type of microcomputer

28. CONCLUSION
WRAPPING ALL THE INFORMATION,
In conclusion, each type of computer—supercomputer,
mainframe, minicomputer, and microcomputer—serves a
unique purpose. Supercomputers handle massive tasks,
mainframes support large-scale organizations, minicomputers
offer mid-range performance for businesses, and microcomputers
provide accessible personal use. Understanding these distinctions
allows us to choose the right system for efficiency and innovation.
