Keyboard A keyboard is a series of switches connected to a microprocessor that monitors the state of each switch and initiates a specific response to a change in that state.
6
Keyboard The most common keyboards are: 101-key Enhanced keyboard 104-key Windows keyboard 82-key Apple standard keyboard 108-key Apple Extended keyboard

Scanner Optical Device similar to a copier
22
Scanner Designed to make copies of images & text for use with a computer
23
Scanner Images Converts Analog signal copy to a Digital signal copy that a computer can use
24
Scanner Text Converts the text into digital format via OCR (Optical Character Recognition) software
25
Scanner OCR Recognizing the text on a document to be able to convert it to editable text a word processing or other software can use
26
Digital Camera Allows users to take pictures and store the photographed images digitally.
27
Digital Camera When you take a picture, light passes into the camera lens, which focuses the image on a charge- coupled device (CCD). The CCD generates an analog signal that represents the image.
28
Digital Camera An analog-to-digital converter (ADC) converts the analog signal to a digital signal. A digital signal processor (DSP) stores the digital image on the camera’s storage media.
29
Digital Camera The images can be transferred to a computer via a USB/Serial/Firewire connection
30
Audio Recording sound for use with a computer
31
Audio Voice Recognition Computer software interprets spoken words and converts them into digital form
32
Audio Music Computer software interprets music signals from Midi (Musical Instrument Digital Interface) compatible instruments and converts them into digital form
33
Audio Music Direct recording of music through a sound card input interface Wav (Wave files) a digital representation of an analog signal
34
