I. Mac sublayer Basics1. the MAC Sub-layer has two main functions: addressing (MAC address), that is, addressing the target node; second, it is used to prevent multiple users from competing to share physical media or channels.2. Two Channel types: point-to-point channel, which requires no intermediate device between two nodes and encapsulates point-to-point data link layer protocol; and broadcast channel, it is a situation where a channel is shared by multiple links (shared channels and physical
