This article mainly introduces what the abbreviation of the media access control sublayer in the local area network refers to. What is introduced in this article is very detailed and has a certain reference value. Interested friends must finish reading it!

The abbreviation of the media access control sublayer is "MAC", which defines how the data frame is transmitted on the media, and solves the problem of how to allocate the right to use the channel when the use of the common channel in the local area network is competitive. In links that share the same bandwidth, access to the connection media is on a first-come-first-served basis.

The abbreviation for the media access control sublayer is "MAC".

The data link layer of LAN is divided into two sublayers: logical link layer LLC and media access control MAC.

Logical link control (Logical Link Control or LLC) is the upper part of the data link layer in the local area network. Logical link control protocol is defined in IEEE 802.2. The user's data link service provides a unified interface to the network layer through the LLC sublayer. Below the LLC sublayer is the MAC sublayer.

MAC (medium access control) belongs to a sublayer under LLC (Logical Link Control). Two media access control methods are widely used in local area network, which are:

1. Contention media access control, also known as random media access control protocol, such as CSMA/CD mode.

2. Deterministic media access control, also known as orderly access control protocols, such as Token (token) mode.

Media access Control (medium access control) is referred to as MAC. It is to solve the problem of how to allocate the right to use the channel when the use of the common channel in the local area network is competitive.

It defines how data frames are transmitted on the media. In links that share the same bandwidth, access to the connection media is on a first-come-first-served basis. Physical addressing is defined here, and logical topology (the path of signals through the physical topology) is also defined here. Line control, error notification (no correction), frame delivery sequence, and optional flow control are also implemented in this sublayer.
