Short for Cellular Digital Packet Data, a data transmission technology developed for use on cellular phone frequencies. CDPD uses unused cellular channels (in the 800- to 900-MHz range) to transmit data in packets. This technology offers data transfer rates of up to 19.2 Kbps, quicker call set up, and better error correction than using modems on an analog cellular channel.

Short for CD-ROM/eXtended Architecture, a specification developed by Sony, Phillips and Microsoft that enables many different types of data — audio, video, compressed video, and graphics — to be stored on a single CD-ROM.
- CD-ROM player
Also called a CD-ROM drive, a device that can read information from a CD-ROM. CD-ROM players can be either internal, in which case they fit in a bay, or external, in which case they generally connect to the computer’s SCSI interface or parallel port. Parallel CD-ROM players are easier to install, but they have several […]
