Answer / shahid
Store and forward stores complete frame in buffer so it is memory intensive and I think this will take time also.
Cut-through doesn't store complete frame, it looks till destination MAC address and forwards, downside is that the corrupt frame will also be forwarded (in store & forward if frame is corrupted, not get forwarded)
In modified cut-through first 64 bytes are checked and then frame is forwarded (corrupt frame is not forwarded also).
