EXPLANATION:-

The Input Devices take input in different forms from the user and convert it into a form which the machine can understand.

• The Keyboard is an input device by which we can enter text, numbers and special characters.
• The Scanner creates a digital form of any printed image by scanning it. Once the image has been scanned, it is transferred to the computer's memory
• The Mouse is a pointing device used in a graphical user interface such as the Windows operating system.

The Output Devices display the output, i.e., information which has been obtained after processing the data.

• The Monitor is known as the Visual Display Unit (VDU). There are different types of monitors such as Liquid Crystal Display (LCD) monitors, Light-Emitting Diode (LED) monitors and Plasma monitors.
• The Printer is used to give output in printed form. The printed output is called a hard copy. A printer can print in black and white or colour, depending on the features available on it
• Speakers are used to output sounds, voice, and music from the computer system. The sound quality is very good since it is digital sound.
