What Does Mac Address Stand For?

Answer

MAC address stands for media access control or medium access control.

Media access control:

It is the network policy that determines how the data is transmitted between the two different terminals with the assistance of network cables. In the OSI model, the 2 layers of the data link layer the media access control policy involve in it. the central goals of this media access layer are,

• Make sure there are no collisions between the transfer of packets.
• Smooth transfer of packets between the two computer terminals.

A collision occurred when the simultaneously two or more two terminals transfer data. a collision cause breaks down the communication which proves costly for an organization and bends heavily the data transmission.

Methods of media access control:

The channels through which data is transferred between nodes to avoid collision there are four ways to achieve these goals. It includes

• Token priority
• CSMA/ CD (carrier sense multiple access with detection).
• Demand priority
• CSMA/CA (carrier sense multiple access with collision avoidance)

In the OSI model:

The OSI model (open system interconnection) is defined as it is the framework of the network that determines how data is transferred between the heterogeneous system. The second-lowest layer is the data link layer which is further divided into two sublayers,

• LLC (the logical link layer)
• MAC (the medium access control)

Functions:

• In the upper layers of the OSI model, it provides a distraction from the physical layer to the logical link layer.
• For smooth transmission over the physical medium,  provides the encapsulated frame.
• It settles out the addressing of the destination and source station as well as destination stations.
• It resolves the problem of collision and if the collision occurred it stimulates the transmission.
• It provides protection against errors which is why it provides a frame check sequence.
• When more than one data frame is transmitted it provides multiple access solutions.
• For transmission, it also determines the channel access methods.
