e
A pure ALOHA network transmits 200- bit frames on a shared channel of 200 kbps. What is the requirement to make this frame collision-free?
f
Prove that a receiving station can get the data sent by a speci fic sender if it multiplies the entire data on the channel by the sender’s chip code and then divides it by the number of stations
g
How is the next hop address returned by the routing algorithm used? 4
