data link layer
data link level
layer 2

Layer two, the second lowest layer in the OSI
seven layer model. The data link layer splits data into
frames (see fragmentation) for sending on the {physical
layer} and receives acknowledgement frames. It performs error
checking and re-transmits frames not received correctly. It
provides an error-free virtual channel to the network layer.
The data link layer is split into an upper sublayer, {Logical
Link Control} (LLC), and a lower sublayer, {Media Access
Control} (MAC).

Example protocols at this layer are ABP, Go Back N,
SRP.
