|
The LLC sublayer adds a header and a trailer to the data.
|
|
|
Logical link control is implemented in software to communicate with the upper layers of the protocol suite.

Explanation:
Detailed explanation-1: -The logical link control sublayer handles multiplexing, demultiplexing, flow control and error detection. In short, these roles mean that packets of data are sent parceled into frames. This is done at a rate both the sending and receiving systems can handle, without errors in the final data.
Detailed explanation-2: -Logical link control is implemented in software and enables the data link layer to communicate with the upper layers of the protocol suite. Logical link control is specified in the IEEE 802.2 standard. IEEE 802.3 is a suite of standards that define the different Ethernet types.
