NT1210 Midterm Study Guide

* The term troubleshooting refers to finding a problem and evaluating it so that corrective action can be taken. * Extensive digitization is a process that began in the 1960s. * Networks have more than just a physical component. * International standards-setting bodies can affect standards established in the United States. * A bus topology does not form a closed loop. * The bit interval is the duration it takes a single bit to be transmitted. * Data communications is a subset of telecommunications. * Data can include or convey graphic images, sound, or video files. * The physical layers of the OSI and TCP/IP models are very similar. * The data communications phase associated with digitization is the first phase. * The portion of an IP address from which bits are borrowed when subnetting is the host. * The transport layer ultimately passes data up to the application layer. * A MAC address is associated with the Data Link Layer. * An IP address is associated with Network Layer. * Twisted pair, Coaxial and Fiber Optic are types of cable * The capacity of a circuit to carry data is its bandwidth. * A 32-bit bus can handle four times the data bits as an 8-bit bus. * LAN resources might include software, hardware and data. * Data bits are frequently passed through pins in a connector. * Synchronous protocols are the type of data link protocols primarily used to delineate groups of bits or bytes: * A circuit is the link that provides the physical means by which data are transferred. * Circuit configuration affects the way in which two or more communicating devices share their link with each other. * The two basic circuit configuration forms are point-to-point and multipoint. * Five factors are considered when selecting a transmission
