ATM (Asynchronous Transfer Mode) The international standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media, such as E3, SONET, and T3. Bandwidth The difference between the highest and lowest frequencies available for network signals. The term also is used ...

NCS 350 - Chapter 6 - Frame Format, Questions and answers, 100% Accurate. Is a switched network passive while an AP is active? - -the network can be considered passive when an AP is active but not actively transmitting data. The network becomes active when data traffic flows between wireless clients and the wired network infrastructure. The state of activity or passivity depends on whether there is data communication occurring at any given moment. IEEE 802.3 frame format - -Preamble (7...
