Input and Output devices and differentiate between them

 Input and Output devices and differentiate between them
Points : Distinguish between input and output devices and between them, two input and output devices, monitor type, general purpose monitor, special purpose monitor, special purpose monitor, commonly used Write the names of the input and output devices and briefly describe their different parts. The following are some commonly used output devices: keyboard, mouse, trackball, light pen, joystick, touch screen, magnetic ink reader, optical character reader (OCR), scanner, voice sensor , Computer output on monitors, printers, plotters, microfilm (com)

Input Devices

Devices that are used to feed data and information into a computer are called input devices.

Output Devices

The devices that are used to produce results in the external world of computers are called output devices.

Differentiate between Input and Output devices
	Input Device	Output Devices
1.	Devices that feed data and information into a computer are called inputs.	The device used to give results to the world of computer ordering is called output devices.
2.	Input devices that perceive people change what changes in a computer.	Reverse output devices. They turn machine language into a language that people can understand.
3.	There are two types of input hardware. I.e. 1. Keyboard devices 2.Non-keyboard or direct entry devices	There are two types of output devices. Namely 1. Soft copy output device 2. Hard copy output device
4.	Commonly used input devices are keyboard and mouse,	Commonly used output devices are monitors and printers.

Explain two Input and Output devicesInput DevicesKeyboard: A keyboard is a device used to feed data into a computer. It's like a typewriter.TypesXT Keyboard (Extended Technology Keyboard)AT Keyboard (Advanced Technology Keyboard) (c) Improved KeyboardDivision of Keyboard

The standard keyboard design is similar to a typewriter. The keyboard is divided into four types of key pads.i Alphanumeric key padii. Numeric key padiii Function key padiv Special Function Key PadMouse

The mouse is an input device called a "pointing device". It is connected to the CPU via a wire, the mouse is used to select different options or draw lines. It has two buttons at the front and a small ball at the bottom. The mouse is placed on a flat rubber pad. When the mouse is moved, the ball moves and an arrow or cursor moves on the screen in the direction of the mouse's movement. The mouse helps to move the cursor around the screen faster. Inside the mouse, there are two cylinders on either side of the ball. When the ball moves, it presses the cylinders that use LED (light emitting decode) technique to signal the computer. Mouse can be useful when working with word processing editing programs, graphic programs, etc. Mouse is easier and faster to use than keyboard keys.

Output Devices

Monitor

To display the result or output from the computer, a screen-like TV is used called a monitor. Also called CRT (Cathode Ray Tube), Screen VDT ​​(Video Display Terminal) and VDU (Video Display Unit). They provide soft copies of information or results while, when entering data, monitors help us display the data so that the correct data can be fed. It also displays all common and error messages. Different sizes and different quality monitors are available in the market.Types of Monitors:Monitors are available in two major types.MonochromeColourThe monitor is divided into three types according to its purpose.General Purpose Monitors:They have CGA, HGA, FGA, VGA and SVGA systems for general business and personal applications.Advanced Purpose MonitorsThey have PGA, TIGA and XGA for scientific and graphical business applications.Special Purpose MonitorsThey are developed for special purpose having ability to display A4 and A3 size used for publishing business.PrintersA printer is an output device with the following features.This results in a permanent hard copy of the information on paper.It retrieves information from a computer and prints it on paper.It accepts many signals from the computer, used to control the printer.Now color printers are also available in the market to get color output.Printers are divided into two types.i.
