1550 Executive Drive, Elgin, IL 60123. (800) 624-2926.
A color graphics card used to increase the number of colors displayed on your monitor to 256 colors. Also used to support larger monitors.
It is posted as monitors and greatly increase the color performance of your computer system to include a palette of over 16 million colors.
Length of time required for a hard disk, CD-ROM drive or other similar device to find the data stored on it. Generally measured in milliseconds (ms).
A video image that is stored as a still video frame that can be displayed on a TV or monitor.
A software package that allows a user to create interactive media and multimedia presentations.
A printed code that corresponds to a specific location(s) on a Laserdisc. A barcode scanner reads the code and allows you to locate and play any image or sequence on a LaserDisc.
(Constant Angular Velocity) Term used to describe an interactive LaserDisc where each frame has its own access number and a user can access individual frames randomly and in any sequence they desire. A CAV LaserDisc can store up to 54,000 individual images or 30 minutes of fully random access motion video.
The first level of LaserDisc interactivity where you access images and motion sequences from a LaserDisc using a remote control or barcode reader.
The third level of interactivity where the LaserDisc is controlled through a computer using special software program such as Macintosh HyperCard or IBM Linkway Folders.
(Compact Disc Read Only Memory) The storage capacity of a single CD-ROM is 683 megabytes of data or about 600 high density floppy disks. Information is pre-recorded on the disc and cannot be changed or erased. A CD-ROM drive is required.
(Constant Linear Velocity) Describes a LaserDisc with information stored in a linear or straight-line fashion. Typically plays from beginning to end with minimal interaction, like a movie. Using software or a barcode, you can create limited random access. Stores one hour of motion per side.
An image that has been converted to electronic data that can be read and brought into the computer for use with other applications. Digitized information must be converted to a NTSC signal to export to a TV or VCR.
Translates the analog signals to digital signals that can be understood by the computer. Allows you to capture an image, present it on screen and save it to disk for use in other applications.
IBM software which, when used with Linkway and a corresponding LaserDisc, allows rapid access of frames and sophisticated branching.
An internal or external piece of hardware used to increase the storage capacity of your MAC or IBM system. Multimedia can use large amounts of memory; therefore additional hard drive storage would be recommended.
A 12" disc which stores a large amount of information. There are two types of LaserDiscs: CAV and CLV (see respective definitions) differentiated by the way information is stored and accessed on the disc.
MAC software which, when used with HyperCard and a corresponding LaserDisc, allows rapid access of frames and sophisticated branching.
Advanced LCD (liquid crystal display) technology that improves contrast by adding a transistor to each monochrome or red, green and blue pixels. The transistor allows more current to illuminate the pixel.
Common LCD technology that illuminates a pixel by sending current down the appropriate row and column.
(Musical Instrument Digital Interface) An international specification used by electronic musical instruments to communicate with computers, mixers and other devices.
(Multimedia Personal Computer) An MS-DOS computer with a CD-ROM drive, audio board, Microsoft Windows with multimedia extensions and audio output. Minimum configuration is a 286 microprocessor running 10MHz with 2mb RAM, a 30 mb hard drive and VGA display.
Combination of different communication tools such as text, visual graphics, sound, still images and motion video. When used together these media create a highly versatile teaching tool that helps a broad spectrum of students learn.
Multi-session drives are fully capable of playing and reading all images on a multi-session Photo CD disc. (Multi-session means that photos can be put on the same CD-ROM multiple times.) If you put your photos on a CD-ROM at a single time, multi-session may not be needed.

(National Television System Committee) Video composite signal that is generated by TVs, VCRs and camcorders. NTSC signal must be digitized for a computer to recognize and use.
One billionth of a second. Commonly used to measure the speed on memory chips (SIMMs, RAM, DRAM, etc.)
(Optical Character Recognition) Software that converts the characters of an image file into text that's ready to manipulate within your word processor.
CD-ROM storage process in which an authorized photoprocessor transfers your 35mm film images onto a Kodak Photo CD Master Disc. You can then view and use the disc either on your desktop computer, using a single session or multi-session Photo CD compatible CD-ROM drive, or on a TV using a Photo CD Player.
Apple's system software extension for the Macintosh. Provides for the integration sound, video and animation.
(Random Access Memory) Part of the computer's memory used for short-term retention of information (i.e., until power is turned off).
A recording or playing speed that shows things as they occur, between 24-30 frames per second.
(Read Only Memory) Part of the computer's memory used for programs that are seldom or never changed (i.e., parts of the operating system). Unlike RAM, you cannot write information to it.
(Single In-line Memory Modules) Installed to increase the computer's operating memory capacity and speed of your system. Additional memory is always desirable when working with multimedia.
Drives which can access images writing to a Photo CD during a single recording session. (You send your photos to be put on a CD one time only for that CD).
Computer technology involving a glove and goggles that allows the user to experience 3-D interaction with the computer.
(Video System Control Architecture) A platform-independent protocol designed by Sony to provide computer control of multiple video devices.
(Video RAM) A special type of DRAM used in high-speed video applications. More VRAM equals higher color saturation and improved performance.
