Baseband Communications channels which carry data without modulation and are therefore slower and less capacious than broadband, although probably more reliable. Typically used for local area networks. When the channel is transmitting bits, one baud equals one bit per second. Bauds are used to measure the speed of a communications channel. Bridge Hardware used to connect similar networks.
Examples are satellite and fibre optic cable systems.
A compact disk used to carry data rather than, or as well as, audio in permanent memory. CD-ROMs can store up to 660 Megabytes of data, making them useful for large databases or multimedia applications. Also a link to a host computer. Circuit switching A form of data communication which establishes a single connection or circuit between source and destination to carry the data stream. Like a conventional telephone system.
