A CRT consists of a phosphor-coated screen and one or more electron guns to draw the screen image.
crucible -1. a vessel for holding high temperature materials 2.
CSA (Canadian Standards Association) -an association that develops standards and does some product testing.
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) -a protocol that causes computers to use the same communication line by waiting for turns. This is used in networks such as Ethernet.
CSNET (Computer+Science NETwork) -a large network that was merged with BITNET.
CTS (Clear To Send) -used to prevent collisions in asynchronous serial communications.
current loop -communications that use a full electronic loop to reduce the effects of induced noise. RS-422 uses this.
current rating -this is typically the maximum current that a designer should expect from a system, or the maximum current that an input will draw. Although some devices will continue to work outside rated values, not all will, and thus this limit should be observed in a robust system. Note: exceeding these limits is unsafe, and should be done only under proper engineering conditions.
current sink -a device that allow current to flow through to ground when activated.
current source -a device that provides current from another source when activated.
cursors -are movable trackers on a computer screen which indicate the currently addressed screen position, or the focus of user input.
