Can someone explain to me why the IFG is 96 bits long? whats the underlying reason for this ? I have given it a search but i couldnt find any good explanations for this. Thanks in advance
Second result in Google when searching for "Reason for Inter Frame Gap":
The sole reason for the 9.6 microsecond interframe gap is to allow the station that last transmitted to cycle its circuitry from transmit mode to receive mode. Without the interframe gap, it is possible that a station would miss a frame that was destined for it because it had not yet cycled back into receive mode.
Technically wrong though; it's not 9.6 micro seconds, its 96 bits - the time represented by 96 bytes is dependent on the negotiated link speed.
