milliwatt (mw). One thousandth of a watt. modem (modulator/demodulator). (1) A functional unit that modulates and demodulates signals. One of the functions of a modem is to enable digital data to be transmitted over analog transmission facilities. (T) (A) (2) A device that converts digital data from a computer to an analog signal that can be transmitted on a telecommunication line, and converts the analog signal received to data for the computer. multicast. (1) Transmission of the same data to a selected group of destinations. (T) (2) See LAN multicast. multicast address. See group address. semiconductor materials are often layered together to obtain a rectifying action between the two dissimilar materials (CMOS). nanosecond (ns). One thousand millionth (10−9) of a second. NetBIOS. Network BIOS. An operating system interface for application programs used on IBM personal computers that are attached to the IBM Token-Ring Network. See also BIOS. network. (1) An arrangement of nodes and connecting branches. (T) (2) A configuration of data processing devices and software connected for information interchange. network server. See server. N NMOS. Negative-channel metal oxide semiconductor. n-type semiconductor. A semiconductor doped with donor impurities that when energized generates a predominance of negative charge carriers (free electrons). Contrast with p-type semiconductor. See also NMOS. N-type semiconductors have a higher level of conductivity than p-type semiconductors and have faster switching rates, but allow lower-density packing of components. P-type and n-type negative-channel metal oxide semiconductor (NMOS). A technology used in the manufacture of field-effect transistors that utilize the properties of an n-type semiconductor material, usually doped silicon, and that when energized, produce a flow of negative charge carriers. nonvolatile. (1) Pertaining to a storage device whose contents are not lost when power is cut off. (T) (2) Contrast with volatile. Glossary 303
