The document presents an overview of computers including their classification, hardware, software, input devices, output devices, and common usages. Computers are classified as microcomputers, minicomputers, mainframe computers, or super computers depending on their computing ability and processing speed. Hardware refers to the physical components of a computer system while software provides instructions for operating the computer. Input devices capture information and translate it into a format the computer can process, and output devices present information from the computer in a way users can understand. Examples of computer uses mentioned are networking, media storage, graphics design, banking, gaming, and more.

4. Introduction
The term computer is derived from the word compute. A
computer is an electronic device that takes data and instructions as
an input from the user, processes data, and provide useful
information known as output.

5. Classification of computer
Computer is classified into several categories depending on their
computing ability and processing speed. These include
• Microcomputer
• Minicomputer
• Mainframe computer
• Super computer

6. Hardware
The electronic device is known as hardware. Computer
hardware is the physical part of the computer system, the
machinary and equipment.
Internal hardware devices include motherboard,hard drives,
and RAM. External hardware devices include monitors, keyboards,
mice, printers, and scanners.

7. Software
Software is a collection of computer programs and related
data that provide the instructions for telling a computer what to do
and how to do it. In other words, software is a conceptual entity
which is a set of computer programs, procedures, and associated
documentation concerned with the operation of a data processing
system.

8. Input devices
Input devices captures information and translates it
into a form that can be processed and by other parts of
your computer.

9. Output devices
Output devices take information within your computer and
present it to you in a form that you can understand.

10. Usage of computer
• Network attached storage
• Media server
• Graphics design
• On-line banking
• Gaming
• Social networking
• Knowledge sharing
• Science

11. Conclusion
Computer security attempts to ensure the confidentiality,
integrity, and availability of computing systems and their
components.
