• ISO Lower Layers and IEEE 802 Layering

Higher

Layers

Data Link

Layer

Physical

Layer

Logical Link Control:

Establishes, maintains and

terminates the logical links

Medium Access Control:

Controls access to the shared

transmission medium

Physical Layer:

Defines the nature of the

transmission medium, the signaling

and how devices are attached

Major difference between the OSI DL Layer and

LLC Layer is that multiple endpoints to the data link

can exist in the LAN model.
