(66) is a protocol that a host uses to inform. a router when it joins or leaves an Internet multicast group． (67) is an error detection code that most data communication networks use． (68) is an interior gateway protocol that uses a distance vector algorithm to propagate routing information． (69) is a transfer mode in which all types of information are organized into fixed form. cells on an asynchronous or non -periodic basis over a range of media. (70) is an identifier of a web page. A．SMTP B．ICMP C．RARP D．IGMP

Microwave communication uses high-frequency(71)waves that travel in straightlines through the air. Because the waves cannot(72)with the curvature of the earth, they can be(73)only over short distance. Thus, microwave is a good(74)for sending data between buildings in a city or on a large college campus. For longer distances, the waves must be relayed by means of "dishes" or(75). These can be installed on towers, highbuildings, and mountain tops. A．optical B．radio C．electrical D．magnetic
