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

|
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.

|
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
|

|
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

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. |
