网络协议 网络协议是网络中控制数据流动的一套规则。其目的通常是确保数据快速、准确地从一点传送到另一点。网络协议涉及自动差错检测、校正以及恢复规程问题,以便能以有序的方式处理偶然发生的事故。 网络可能有几级协议,如图4-1所示。该图示出了具有两个集中器的网络;计算机正发
Network Protocol Network protocol is a set of rules that control the flow of data in the network. The goal is usually to ensure that data is transmitted from one point to another quickly and accurately. Network protocols involve problems with automatic error detection, correction, and recovery procedures so that incidental incidents can be handled in an orderly fashion. The network may have several levels of agreement, as shown in Figure 4-1. The figure shows a network with two concentrators; the computer is starting
