A keyboard is a human interface device which is represented as a layout of buttons. Each button, or key, can be used to either input a linguistic character to a computer, or to call upon a particular function of the computer.

PPointingointing DDevicesevices

A pointing device is any human interface device that allows a user to input spatial data to a computer.

MOUSE

JOYSTICK

TRACKBALL

MMouseouseA mouse is a

pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons.

JJoystickoystickA joystick is an

input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer.

TTrackballrackballA trackball is a

pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down mouse with an exposed protruding ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a cursor.

SScannercanner

A scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image.

Digital CameraA digital camera,

as opposed to a film or video camera, uses an electronic sensor to transform images (or video) into electronic data. Modern digital cameras are typically multifunctional and the same device can take photographs, video, and/or sound.

HHard ard DDriverive

A hard disk drive (often shortened as hard disk, hard drive, or HDD) is a non-volatile storage device that stores digitally encoded data on rapidly rotating platters with magnetic surfaces.

FFloppy loppy DDriverive

A floppy disk is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell.

RRemovable emovable HHard ard DDiskisk• A type of disk drive system in

which hard disks are enclosed in plastic or metal cartridges so that they can be removed like floppy disks. Removable disk drives combine the best aspects of hard and floppy disks. They are nearly as capacious and fast as hard disks and have the portability of floppy disks. Their biggest drawback is that they're relatively expensive.

CD-ROM DCD-ROM Driverive• is a pre-pressed

compact disc that contains data accessible to, but not writable by, a computer for data storage and music playback, the 1985 “Yellow Book” standard developed by Sony and Philips adapted the format to hold any form of binary data.

OUTPUT DEVICESOUTPUT DEVICESAn output device is any piece of computer

hardware equipment used to communicate the results of data processing carried out by an information processing system to the outside world.

MONITOR PRINTER

MMonitoronitor• A monitor or display

(sometimes called a visual display unit) is a piece of electrical equipment which displays images generated by devices such as computers, without producing a permanent record. The monitor comprises the display device, circuitry, and an enclosure.

PPrinterrinter

A printer is a peripheral which produces a hard copy (permanent readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies.

SSpeakerpeaker

Computer speakers, or multimedia speakers, are external speakers, commonly equipped with a low-power internal amplifier.
