The ability of a dielectric material between conductors to store electricity when a difference of potential exists between the conductors. The unit of measurement is the farad, which is the capacitance value that will store a charge of a one coulomb when a one-volt potential difference exists between the conductors. In AC, one farad is the capacitance value, which will permit one ampere of current when the voltage across the capacitor changes at a rate of one volt per second.

|Carrier Sense Multiple Access/Collision Avoidance||
A network media access method that sends a request to send (RTS) packet and waits to receive a clear to send (CTS) packet before sending. Once the CTS is received, the sender sends the packet of information. This method is in contrast to CSMA/CD, which merely checks to see if any other stations are currently using the media.

|Carrier Sense Multiple Access/Collision Detect (CSMA/CD)||
A network media access method employed by Ethernet. CSMA/CD network stations listen for traffic before transmitting. If two stations transmit simultaneously, a collision is detected and each station waits a brief (and random) amount of time before attempting to transmit again.

Also called CAT-1. Unshielded twisted pair used for transmission of audio frequencies up to 1MHz. Used as speaker wire, doorbell wire, alarm cable, etc. Category 1 cable is not suitable for networking applications or digital voice applications. See Chapter 1 for more information. Not a recognized media by ANSI/TIA-568-C.
