Cisco Certified Technician; Questions and Answers 100% Solved ATM (Asynchronous Transfer Mode) ANSWERThe 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 ANSWERThe difference between the highest and lowest frequencies available for network signals. The term also is used to describe the rated throughput capacity of a given network medium or protocol. The frequency range necessary to convey a signal measured in units of hertz (Hz). For example, voice signals typically require approximately 7 kHz of bandwidth and data traffic typically requires approximately 50 kHz of bandwidth
