What is the difference between the data link layer and link layer?

What is the difference between the data link layer and link layer? Do they mean the same thing?

Solution

  • Despite the different semantics of layering in TCP/IP and OSI, the link layer is often described as a combination of the data link layer and the physical layer in the Open Systems Interconnection (OSI) protocol stack.

    The link layer of the TCP/IP model is often compared directly with the combination of the data link layer and the physical layer in the Open Systems Interconnection (OSI) protocol stack. Although they are congruent to some degree in technical coverage of protocols, they are not identical. The link layer in TCP/IP is still wider in scope and in principle a different concept and terminology of classification.
