4、分，可以将计算机网络分为电路交换、报文交换、分组交换和。2.接口是分层模型中一个很重要的概念。接口通常由三部分组成，即：语义部分、语法部分和。3.OSI/RM 模型分为 7 层，其中，层需要处理数据帧的丢失、损坏和重复发送，需要避免发送方的发送速率比接收方大导致的问题。4.分组交换将用户的报文分成若干个固定长度的分组，以分组为单位在网络中传输。因此，在分组交换网络中，最重要的是如何管理好这些分组流，通常有两种方法：数据报和。5.数据链路层实现的主要功能包括为网络层提供服务、链路管理、成帧与帧同步、差错控制、流量控制、数据的透明传输和寻址等。目前，主要成帧方法有以下四种：、带字符填充的首尾字符定
