1、Serialization delay and （71）delay are the two components of network delay that are improved by increasing bandwidth. Serialization delay, i.e. the amount of time it takes to put the（72）on the wire, and queuing delay (depth of  the queue) are improved by increasing the（73）from a 128Kbps circuit to a T1. However, three other components of delay, routing/switching delay, distance delay, and protocol delay are components that can not be positively affected by an（74）in bandwidth. If the circuits are not over-utilized, then increasing the bandwidth to improve the（75）of the application will only result in an increased bandwidth with no positive effects on performance .
A、 memory
B、 cache
C、 bandwidth
D、 delay


答案:C
答题解析:

串行延迟和等待延迟是网络延迟的两个组成部分，它随着渐增的带宽而有所改善。串行延迟也就是数据在线路上传输所花时间的总计，带宽从128Kbps提高到T1信道速率改善了等待延迟（等待程度）。然而，另外三个延迟的成分：路由/交换延迟、距离延迟、协议延迟却肯定不会因此（渐增的带宽）而受到影响。如果这些线路不能被完全利用，那么扩展带宽以提高应用的性能将只会导致更高的带宽，但绝对不会对性能有任何积极的影响。
