HARDWARE COMPONENT
FUNCTION
1.      
Optical Disk Drive
optical disk drive (ODD) uses a laser light to read data from or write data to an optical disc. These include CDs, DVDs, and Blu-ray discs. This allows you to play music or watch movies using pre-recorded discs
2.      
Keyboard
A computer keyboard is an input device used to enter characters and functions into the computer system by pressing buttons, or keys. It is the primary device used to enter text.
3.      
Motherboard.
the motherboard establishes vital electronic connections between these various hardware units to ensure that tasks undertaken by the user are completed successfully and efficiently
4.
Power Supply Unit
power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies


DIFFERENTIATE THE FIVE GENERATION OF COMPUTER ACCORDING TO THE YEAR OF MANUFACTURING, SIZE, SPEED, LANGUAGE USED AND THE OPERATING SYSTEM
1ST Generation
2nd Generation
3rd Generation
4th Generation
5th Generation
By Year
1940-1956
1956-1963
1964-1971
1971-Present
Present and Future
By Size
Very large In size
Smaller than previous generation
Smaller than 2nd generation
Small in size
Smallest in size
By Speed
Very slow in term of speed
 Faster in speed than first generation
More faster than previous generations
Fast in speed
Fastest in speed
Purpose
Easily malfunction
More reliable
became accessible to a mass audience because they were smaller and cheaper than their predecessors
small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet.
The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.
