Glossary broadband A network that transmits signals as variations of carrier waves rather than directly as pulses. Broadband networks provide greater network bandwidth capacity, but are also more complex. broadcast To send a message to all workstations connected on the network. buffer A temporary storage space. Data may be stored in a buffer before, during, or after a data transmission. Buffers are often used to compensate for the difference between the speed of data packet transmission and the speed of data packet processing. bus An electrical connection over which information is transported. bus topology A network topology in which all devices are connected to a central cable called the bus or backbone. Bus networks are relatively inexpensive and easy to install. Ethernet, a very popular LAN, uses a bus topology. byte A group of eight consecutive bits that are treated as one unit. channel A path between a sender and receiver that carries one stream of information. A two-way path is called a circuit. client A client PC is any PC connected to a network that does not act as a server. Client/Server Architecture A networking architecture in which each computer or process on the network is either a client or server. A server is a powerful computer or process dedicated to managing disk drives (file server), printers (printer server), or network traffic (network server). Clients are normally less powerful PCs or workstations on which users run applications and issue requests to servers for resources. coax cable A type of network medium. Coaxial cable contains a copper inner conductor surrounded by plastic insulation and then a woven copper or foil shield. It is commonly used in cable television and Ethernet networks. CRC Cyclic Redundancy Check. A CRC is calculated by the Media Access Control (MAC) transmit process and checked by the MAC receive process of a workstation to ensure integrity of the frame contents. CSMA Carrier Sense Multiple Access. CSMA is a medium-sharing scheme in which network workstations listen on the network medium and transmit only if the cable is not in use. CSMA is often combined with a collision detection scheme for more efficient data transmission. 109 English
