• The Mouse – An input device that allow user to command computer through dragging and clicking.
• The Keyboard - The keyboard is still the most common way of entering information into a computer

Scanners - allows you to scan printed material and convert it into a file format that may be used within the PC. Touch Pads - A device that lays on the desktop and responds to pressure Light Pens - Used to allow users to point to areas on a screen Joysticks - Many games require a joystick for the proper playing of the game

TWO TYPES OF STORAGE DEVICESPRIMARY STORAGE DEVICE –
STORE DATA TEMPORARILY (RAM)
SECONDARY STORAGE DEVICE– STORE DATA PERMANENTLY UNLESS INTENTIONALLY DELETED.

READ ONLY MEMORY RAM - Random Access Memory The main 'working' memory used
by the computer.It holds temporary instructions
and data needed to complete tasks. This enables the CPU – to access instructions and data stored in the memory very quickly.
![Page 11: component of computer](https://reader036.fdocuments.in/reader036/viewer/2022062900/58ec24871a28abb3738b458d/html5/thumbnails/11.jpg)
ROM(READ ONLY MEMORY)
The data or program in rom can only be read but cannot be at all.
All the contents in rom can be accessed and read but cannot be changed.
ROM is non – volatile. It holds the programs and data when the computer is powered off.

Hard Disks Speed: Very fast! The speed of a hard disk is often
quoted as "average access time" speed, measured in
milliseconds. The smaller this number the faster the disk.

OUTPUT DEVICES ALLOW THE COMPUTER TO
COMMUNICATE WITH THE USER GIVE/SHOWS/PRINT THE RESULTS
OF OUR INPUT

Printer - The printer produces a hard copy of your output, and the computer screen produces a soft copy of your output.
Monitor – The computer screen is used for outputting information in an understandable format.
Speakers - Enhances the value of educational and presentation products.
Plotters - A plotter is an output device similar to a printer, but normally allows you to print larger images.

A Liquid Crystal Display (LCD) projector uses its own light source to project what is displayed on the computer on a wall or projection screen. A digital light processing (DLP) projector uses tiny mirrors to reflect light which can be seen clearly in a well-lit room.
