Short for complementary metal oxide semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices, such as portable computers. Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.
(1) Short for content management system. (2) Short for color management system.
Short for cable modem termination system, a system of devices located in the cable head-end that allows cable television operators to offer high-speed Internet access to home computers. The CMTS sends and receives digital cable modem signals on a cable network, receiving signals sent upstream from a user’s cable modem, converting the signals into IP […]
Short for Cyan-Magenta-Yellow-Black, and pronounced as separate letters. CMYK is a color model in which all colors are described as a mixture of these four process colors. CMYK is the standard color model used in offset printing for full-color documents. Because such printing uses inks of these four basic colors, it is often called four-colorprinting. […]
Short for Converged Network Adapter, CNA is a technology that supports data networking (TCP/IP) and storage networking (Fibre Channel) traffic on a single I/O adapter. CNAs support both Enhanced Ethernet and Fiber Channel over Ethernet (FCoE).
Short for card-not-present, a term used to describe a merchant situation where the consumer makes a credit card transaction without providing the merchant with the card directly. Card-not-present situations include mail-order, telephone, or Internet transactions.
