Input devices Numeric
Input Devices - Numeric Numeric Keypad - A numeric keypad is a number pad featured on a keyboard – generally on the very far right. It consists of digits 0 to 9 as well as addition, subtraction, multiplication and division signs for calculations and an enter button. way.com/support.gate way.com/s/KBDMous e/ /k jpg
Input Devices - Numeric Barcode Reader – A barcode reader is an electronic device used for reading printed barcodes. This uses a light source, a lens and a light sensor which translates optical impulses into electronic form. stronomy.com/images/e ncyclopediaimages/b/b a/barcode-scanner.jpg
Input Devices - Numeric Magnetic Strip – A magnetic strip is card that is capable of storing data. It is reading by swiping it through a reader head. They are commonly used in credit cards and access cards for security. cor.com/_img/prod ucts/magnetic_car d2.jpg
Input Devices - Numeric Smart Cards – Smart cards are pocket sized cards that have an integrated circuit imbedded within which can process data. The benefit of Smart cards is that they can be used for identification, authentication and data storage. mages/photos/photo- smart-card.jpg
Input Devices - Numeric OMR – Optical mark recognition is the process of capturing human-marked data from document forms such as surveys and tests. This document is fed through a scanner which reads where the dots and corresponds this position to the answer giving a true or false reading. ingwai_lucky/images/OMR. jpg
Input Devices - Numeric MICR – Magnetic Ink Character Recognition is a character recognition technology mainly used by the banking industry to process cheques. This process has a very low error rate in comparison to other Input devices such as OMR ki/File:MICR.svg
Input devices Graphics
Input Devices - Graphic Scanner - A scanner is a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image. Modern scanners use a charger-coupled device or a contact image sensor as the image sensor, whereas older drum scanners use a photomultiplier tube as the image sensor. ner.view.750pix.jp g
Input Devices - Graphic Digital Camera - A digital camera is a camera that takes still photographs as well as video footage, both digitally by recording images using an electronic image sensor. Digital cameras are more cost effective as they do not require film. The camera records onto a memory card that is readable by a computer, this can be wiped and reused as many times as possible. iki/File:Canon_PowerSh ot_A95_- _front_and_back.jpg
Input Devices - Graphic Graphics Tablet - A graphics tablet is an input device that allows the user to draw images and graphics just like on paper and is readable by a computer. A graphics tablet consists of a flat surface upon which the user is able to draw an image using the attached stylus (pen like drawing apparatus). This is useful for classroom work as all written data is transfered into electronic form blog/img/lapazz_6x8_g raphics_tablet.jpg
Input Devices - Graphic Video Frame Grabber - A video frame grabber is an electronic device that captures individual, still frames from an analog video signal or a digital video stream. It is usually a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored or transmitted in raw or compressed digital form.

Input Devices - Graphic Electronic Whiteboard - An electronic whiteboard is an interactive display that connects to a computer and projector. The projector projects the computer’s desktop onto the board’s surface, where users control the computer using a pen, finger or other device (such as a stylus). The board is usually mounted to a wall or on a floor stand. gford.com.au/ca rt/images/ub582 5.jpg
Input Devices - Graphic FAX - A fax (facsimile) is a piece of communication technology used to transfer copies of document, especially using affordable devices operating over the telephone network. The fax machine makes a copy of the desired document and sends this copy down the telephone network. au/images/big_product s/jx200%20fax%20righ t%20- %20low%20res.jpg
Input devices Audio
Input Devices - Audio Microphone - A microphone is a sensor that converts sound into electrical signal. There are used in many different pieces of hardware such as telephones and hearing aids. They work by the vibration of a thin membrane which responds to sound pressure. This movement is translated into an electrical signal.There are many different types of microphones. h.files.wordpre ss.com/2009/0 1/microphone.j pg
Input Devices - Audio Amplifier - An amplifier is purely a device that changes the amplitude of a signal. This signal is generally voltage or current. The sound can then be changed when put through another system. An amplifier can be for a guitar, human voice, headphones or a loud speaker (PA). com/Merchant2/graphics/ /Fender_Princet on_650.jpg
Input Devices - Audio Sound Card - A sound card is a computer expansion card that accommodates for output and input of audio signals to and computer and also from a computer. It is controlled by computer programs. They are commonly used for providing an audio component for multimedia applications for tasks such as music composition, audio/video editing and entertainment. b2b- network.com/direct/db image/ /8_C hannel_Sound_Card.j pg
Input devices Video
Input Devices - Video Digital Video Camera - A digital video camera is used for capturing motion data. They convert the signal directly to a digital output. The data collected save onto either an internal hard drive, disc or memory card/stick that is inserted into the camera itself. ck.com/images/panas onic_vdr_d400_dvd_v ideo_camera.jpg
Input Devices - Video Firewire Cable - A firewire cable is a cable designed for high- speed communication and real time data. Invented Apple Inc. for higher transfer speeds in transferring video data. edata.net/pcjoy.co m/merchantmanag er/images/FW- IEEE-1394A-64- 6FT.jpg
