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.

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

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.
