Differences between data Link layer and transport layer error detection is that:
A. Data link detects transmission errors while transport layer detects segmentation faults
B. Data link detects node-to-node errors while transport layer detects end-to-end errors
C. Data link detects end-to-end errors while transport layer detects node-to-node errors
D. Data link detects segmentation errors while transport layer detects bit error
Solution (By Examveda Team)
In OSI model-Data link layer - layer 2
Transport layer - layer 4
The data after being segmented in the layer 4(transport layer) goes down to layer 3(network layer)and layer 2(data link layer) for packetization and framing.
Transport layer-
This layer divide the data into segments.
It also ensures that data must be received in the same sequence in which it was sent. Protocols used : TCP and UDP
Data link layer -
Encapsulation of packets into frames is done here. These frames are then transferred to the physical layer.
Error correction bits are added are also added.
Flow control, addressing, etc are done here.
