Answer / zgeorgem
1. bit stuffing
2. LRC
3. CRC
4. parity check
here 1 2 3 are either error detection or error correction
which can be potentially done by DataLink Layer
But bit stuffing (from wikipedia) seems to be done by the
physical layer so that the data arrives at the device
synchronized... (i am not sure of the working but i am sure
that it is a layer1 concept)

Answer / yogesh babar
LRC is not done by Data Link Layer.
Reason- Bit stuffing is used in DLL to identify the new frame and the older frame which is recognized by adding 0111 at the end of every frame so that receiver will get idea that from this moment new frame will start.
Regarding CRC is used for to check whether data is altered during transmission or not and parity is also doing the same.
So remaining is LRC which is not present at DLL at all.
