The transport layer divides a data stream into segments and may add reliability and flow control information.
|
|
|
The data link layer adds physical source and destination addresses and an FCS to the segment.

Explanation:
Detailed explanation-1: -The lowest layer, the physical layer, encapsulates the packet, adding a bit sequence specific for each type of network medium.
Detailed explanation-2: -The layers are: Layer 1-Physical; Layer 2-Data Link; Layer 3-Network; Layer 4-Transport; Layer 5-Session; Layer 6-Presentation; Layer 7-Application.
