The devices are usually used for display, projection, or for physical reproduction.
Output Device can produce the final product of machine processing into a form usable by humans. It provides man to machine communication.
Input and Output Devices
The Input Devices are the hardware that is used to transfer transfers input to the computer. The data can be in the form of text, graphics, sound, and text. Output device display data from the memory of the computer.
Output can be text, numeric data, line, polygon, and other objects. The most commonly used input device is a keyboard. The data is entered by pressing the set of keys. All keys are labeled. A Mouse is a pointing device and used to position the pointer on the screen. It is a small palm size box. There are two or three depression switches on the top. The movement of the mouse along the x-axis helps in the horizontal movement of the cursor and the movement along the y-axis helps in the vertical movement of the cursor on the screen.
The mouse cannot be used to enter text. Therefore, they are used in conjunction with a keyboard. JavaTpoint offers too many high quality services. Mail us on hr javatpoint. Please mail your requirement at hr javatpoint. Duration: 1 week to 2 week.

Computer - Input Devices
Keyboard is the most common and very popular input device which helps to input data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing additional functions. These keys include the letter keys A-Z and digit keys 09 which generally give the same layout as that of typewriters. It is used to enter the numeric data or cursor movement.
The Input Devices are the hardware that is used to transfer transfers input to the computer. The data can be in the form of text, graphics, sound, and text. Output device display data from the memory of the computer. Output can be text, numeric data, line, polygon, and other objects. The most commonly used input device is a keyboard.
Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two. An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices. Input devices include typewriter-like keyboards; handheld devices such as the mouse , trackball, joystick, trackpad, and special pen with pressure-sensitive pad; microphones, webcams, and digital cameras.
An output device is any piece of computer hardware equipment which converts information into human read able form. It can be text , graphics , tactile , audio , and video. A new type of Output device is being developed these days, known as Speech synthesizer ,  a mechanism attached to the computer which produces verbal output sounding almost like human speeches. A display device is the most common form of output device. It presents output visually on computer screen.
By the end of this chapter, you will be able to:. In Grade 10, you learned that hardware is the physical components of a computer. This includes items such as the monitor or screen , keyboard and mouse. An input device is any device that allows you to enter data into a computer and interact with it. Common input devices include keyboards, computer mice, touchpads and touchscreens. You also learned about the basics of digital cameras, scanners and readers such as radio-frequency identification RFID , magnetic strip and OCR readers. Other input devices are video and audio input devices such as webcams and microphones, and biometric input devices such as fingerprint scanners.
Сьюзан бессильно прижалась к двери, за которой, всего в нескольких сантиметрах от нее, работала вентиляция, и упала, задыхаясь и судорожно хватая ртом воздух. Сьюзан закрыла глаза, но ее снова вывел из забытья голос Дэвида. Беги, Сьюзан.
