Computer Hardware Components

Five Basic Components of an Information System

• Hardware

  • Hardware is the term referring to all the physical parts in a computer system. It includes the monitor, the keyboard, the mouse, the main case which stores the RAM, CPU and the motherboard.

• Software

• User/People

• Data

• Procedure

Computer Hardware

CPU means ‘Central Processing Unit’. This is the place of computer data handling. Moreover, it does all the data manipulation, calculations and formatting data for output.

The execution of the instructions within the computer system is very fast. It measures it in cycles of time and refers it to as megahertz. That’s why the ‘Mhz’ of a computer’s processor is sometimes referred to as the clock speed. Think about CPUs (and aligned circuitry) beating like a heart, this pulsing/beating is expressed as “MHz” e.g. 2000Mhz.

INPUT DEVICE, this allows users to enter data or commands into the computer system, particularly to CPU. Data can be in the form of numbers, words, actions, commands, etc. The main function of input devices is to direct commands and data into computers. Computers then use their CPU to process this data and produce output:

Here are the examples of an Input Device

1. Keyboard - sends instructions through TYPING

2. Mouse - sends instructions through CLICKING

3. Camera - sends instructions through SCANNING

4. Microphone - sends instructions through RECORDING

The OUTPUT DEVICES are peripheral devices that are used to convert the output processed by the computer into human-readable form. These devices either display the output on the screen, print on paper, or through any other form. Examples: printer, monitor,

INPUT AND OUTPUT DEVICE can either enter commands or instructions to the computer system and generate its digital result

Examples: printer, smart screen, etc.
