3Data Carrier Detect — Abbreviated DCD. A hardware signal defined by the RS 232 C standard that indicates that the device, usually a modem, is online and ready for transmission …
4carrier detect — Abbreviated CD. An electrical signal sent from a modem to the attached computer to indicate that the modem is online. See also Data Carrier Detect; RS 232 C …
5carrier detect threshold — A way of measuring how well a modem can detect valid data over noisy phone lines. It is measured in negative dBm s (decibel milliwatts). The bigger the number (the more negative) the better. For example, 45 dBm is better than 40 dBm. Same as… …

8Carrier sense multiple access with collision detection — (CSMA/CD), in computer networking, is a network control protocol in which *a carrier sensing scheme is used. *a transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam… …
9Carrier sense multiple access — (CSMA) is a probabilistic Media Access Control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared physical medium, such as an electrical bus, or a band of electromagnetic spectrum. Carrier Sense… …
