https://gateoverflow.in/3838/gate2005-it-75 self doubt
In a TDM medium access control bus LAN, each station is assigned one time slot per cycle for transmission. Assume that the length of each time slot is the time to transmit 100bits plus the end-to-end propagation delay. Assume ... division multiple access as only one station uses the medium in its slot? please if someone can clear this doubt.
