The document discusses four types of computers: microcomputers, minicomputers, mainframe computers, and supercomputers. Microcomputers are the smallest and most common, including desktops, laptops, and smartphones. They are inexpensive and portable but have low processing speed. Minicomputers are mid-sized machines for small businesses. Mainframe computers are the largest, filling entire rooms, and are used for centralized computing by large organizations. Supercomputers are the fastest but also the most expensive, used for specialized tasks like modeling and requiring their own facilities to operate.

3. MICRO COMPUTER
 Digital Computer that works on the
microprocessor.
 Used in homes and offices
 Common microcomputers include laptops and
desktops
 Performs task such as word processing , desktop
publishing and accounting.
 Other than personal computers, microcomputers
also include smartphones, notebooks,
workstations and embedded systems.
Advantages:
 Less cost
 Small size
 portable
Disadvantage:
 Low processing speed

4. MINI COMPUTER
 Known as the mid range server.
 Medium size multiprocessing and multi user
Computer.
 Used by small size Companies.
 Popular Minicomputers includes K-202, SDS-92
and IBM Midrange computer
Advantages:
 Cater to multiple user
 Low cost than the mainframe
Computer
Disadvantage:
 Large
 Bulky

5. MAINFRAME COMPUTER
 Known as enterprise server.
 Occupies entire room or floor.
 Used for centralize computing.
 Server distributed user and small server in computing
network.
 Some of the popular mainframe computers are Fujitsu’s ICL
VME and Hitachi’s Z800.
Advantages:
 Supports many users and
instructions.
 Large memory
Disadvantage:
 Huge size
 Expensive

6. SUPER COMPUTER
 Faster and expensive.
 Consist of several Computer that works on the parallel as a single
system
 They are used to perform specialized tasks such as scientific
simulations, weather forecasting, nuclear energy research, and
earthquake studies.
 A supercomputer needs to be kept in large air-conditioned rooms;
some can even occupy an entire building.
 Examples: IBM’s Sequoia, TIANHE-1 and PARAM.
Advantages:
 speed
Disadvantage:
 Generate large amount of heat during the operation.
