See data compression. A string of characters saved by a web browser on the user's hard disk. Many web pages send cookies to track specific user information. Cookies can be used to retain information as the user browses a web site. For example, cookies are used to 'remember' the items a shopper may have in a shopping cart. Cyclic redundancy check; an error checking protocol. A cable that wires a pin to its opposite pin, for example, RX+ is wired to TX+. This cable connects two similar devices, for example, two data terminal equipment (DTE) or data communications equipment (DCE) devices. Control signal lines on an RS-232C serial interface. These lines are needed to use hardware flow control. A special marker on a display. In asynchronous transfers, a character is composed of data bits (the actual information) and framing bits (start bit, stop bit/s, parity bit). The framing bits are needed to recognize whether a character has been successfully transmitted and where a new character starts. Re-coding of information. Less data bits represent the same information. ZyXEL modems use MNP4 and V.42 compression schemes. Block of data that is framed by error control groups. A block consists of up to 256 8-bit groups. Data packets are used in synchronous transfer. The important module doing modulation and demodulation for a modem. The data pump is decisive for the quality and the speed of a modem's transfer capabilities. Data Carrier Detected - a control signal line of the RS-232C interface. Data Communications Equipment is typically a modem or other type of communication device. The DCE sits between the DTE (data terminal equipment) and a transmission circuit such as a phone line. The act of restoring an encrypted file to its original state. Transferring analog signals into digital data bits. Glossary G
