Ensures that messages are delivered error-free, in sequence, and with no losses or duplications |
Transport |
|
|
Controls the operations of the subnet, deciding which physical path the data takes |
Network |
|
|
Provides error-free transfer of data frames from one node to another over the Physical layer |
Data Lin |
|
|
Concerned with the transmission and reception of the unstructured raw bit stream over the physical medium |
