Network performance is significantly () because it isn’t bogged down with the processing and transmission of several large data files; each receiving computer doesn’t have to () the transmitting server for the file.A.entity B.procession C.volume D.message
选项
A.entity
B.procession
C.volume
D.message
答案
D
解析
IP多播是允许同时给网络上很多主机提供数据的一种技术。它并不是每次复制很多副本去发送给每一个在这个IP多播组中的接收者,而是最初只发送单一信息,并没有立即复制信息去发给每个接收者,而是直到到达网络中最近的一个共通点时才开始复制,从而最大限度地减少了对带宽的消耗。网络的性能明显得到改善,一是因为它没有立即处理和传输几个大型数据文件;二是接收端计算机不需要查询该传输服务的文件。
