This document classifies computers based on their size, technology, and purpose. The main types of computers discussed are microcomputers, workstations, minicomputers, mainframe computers, and supercomputers. Microcomputers are the most common and include desktops, laptops, and tablets. Workstations are powerful single-user computers used for tasks requiring significant processing power. Minicomputers are more powerful than microcomputers and can support multiple users. Mainframe computers are very large and powerful machines that can support hundreds or thousands of users. Supercomputers are the most powerful and expensive computers used for advanced tasks like weather forecasting.

2. Computers can be classified based on their
•Size
•Technology
•Purpose

3. The main types of computers are
• Microcomputer
• Workstation
• Minicomputer
• Mainframe computer
• Super computer

4. Microcomputer
A microcomputer is the most common type of computer, whether in a
workplace, at school or on the desk at home.
• The CPU of a microcomputer is a single chip known as the microprocessor.
• These are single-user computers.
• They are mainly used in offices and homes.
• They are the least expensive.
• Eg. Desktop computers, Laptops or Notebook computers, Tablet PC etc

5. Workstations
Workstations are powerful single-user computers.
Features
They are used for tasks that require a great deal of power such as in computer
animations or scientific and mathematical work.
Eg. Computers used in banks and big offices

6. Minicomputers
Minicomputers are more powerful than microcomputers.
Features
• A minicomputer is a multi-user computer, ie, many people can use one
machine at a time.
• It has greater storage capacity than a microcomputer.
• It may be used as a network and internet server.
• Eg. PDP-11, SPARC

7. Mainframe computer
Mainframe computers are very large and powerful computers
Features
• They are faster, more powerful and more expensive than microcomputers or minicomputers.
• They can support hundreds or thousands of users, handling massive amounts of input,
output and storage.
• They are used in large organizations such as banks and government offices .
• They are used as e-commerce servers for handling transactions over the internet.
• Eg. VAX 8842, CDC 6600, IBM 4381

8. Supercomputers
Supercomputers are the most powerful of all computers
Features
• They are the most expensive computers.
• They are massive in size and can occupy a whole room.
• They have several processors which make them very powerful and fast.
• They are used in areas such as weather forecasting, nuclear science etc.
• Eg. CRAY XT5- HE, India’s PARAM
