第2题:
Asynchronous Transfer Mode(ATM)is a(16)that promises to change the fabric of local and wide area communications.The key advantage of ATM is the capability to move voice, data, graphics and(17)at speeds of up to 2 gigabits per second.An ATM switch allows you to create a(18)network that is completely independent from the(19)configuration of the network.ATM uses a(20)called cell switching to convert data into fixed length cells of 53 bytes each, so they can be switched very quickly and efficiently.
