PARTS OF COMPUTER

Computer parts are unlimited considering the fact that any device that could be connected and read by the system unit can be referred to as part of that system. Regardless of the above, it is much cleared that two or more devices could have a similar or same function in the system which makes it easier to us that many parts could be found depending on the environment of the user.

Examples:

1. C.P.U

2. Monitor

3. Keyboard

4. Mouse

5. Printer

6. Speaker

7. Lightpen

8. Joystick

9. Plotter

10. Barcode reader

11. Modem

12. Track ball

13. Digital camera

14. Microphone

15. Flash disk

16. Hard disk

17. Compact disc

18. Memory card

19. Floppy disc

20. Scanner e.t.c

CLASSIFICATION OF COMPUTER

Computer can classify based of the followings;

1. Size

2. Types (capacity)

3. Purpose and 

4. Generation

Classification based on size

There are four different sorts of computers based on their size and how they are configured to operate:

• Microcomputer

• Mini computer

• Mainframe and

• Super computer

Microcomputer: A microcomputer, sometimes referred to as a personal computer (PC), is a type of computer that runs on a smaller scale than traditional computers (Personal Computer). A component that is commonly referred to as a motherboard houses the central processing unit (CPU), a microprocessor, memory in the form of ROM (Read Only Memory), RAM (Random Access Memory), I/O ports, and a bus system of connecting wires. They are the most affordable.

Features of Microcomputers:

• They are extensively employed for personal usage.

• They are smaller and comparably less expensive.

• Multi-user functionality is not supported.

• It has a limited computational capacity.

• They are quite simple to use.

Mini Computer: Minicomputers are used by small businesses and industries. They go by the term "Midrange Computers." These minicomputers frequently have several users, just as mainframe computers. They are a bit slower than mainframe computers.

For example, the manufacturing department may employ minicomputers to keep an eye on specific production processes.

Features of Minicomputers:

• It is smaller than mainframes or supercomputers in terms of size.

• In comparison to a mainframe or supercomputer, it is less costly.

• It is able to perform many jobs at once.

• It may be utilized by several users simultaneously.

• It is utilized by small businesses.

Mainframe: Despite being less efficient than supercomputers, mainframe computers are nevertheless extremely expensive. Large corporations and governmental organizations frequently employ mainframe computers to run everyday operations. They have the ability to store and analyze a lot of data. To maintain information on their customers, students, and insurance policyholders, banks, colleges, and insurance companies utilize them. They may also act as a server in a network environment. Hundreds of users may be managed simultaneously by them.

Features of Mainframe Computer:

• They have enormous amounts of memory.

• They are capable of running several different operating systems.

• They have a significant number of CPUs with powerful processing speeds.

• Tightly Coupled Clustering Technology is employed.

Super computer: The most efficient computers in terms of processing data and performance are supercomputers. These computers are used for research and exploratory purposes. Supercomputers are exceedingly large and highly expensive. It can only fit in large, air-conditioned spaces.

Supercomputers are used for a range of tasks, such as space exploration, seismic research, and the testing of nuclear weapons.
