about Lan/Ethernet
When a collision occurs, IEEE 802.3 systems use an algorithm called binary exponential back off to calculate the random amount of time the sender must wait before at-tempting to retransmit the frame. For each of the retransmissions, the algorithm doubles the range of the random delay. After n collisions, the system will wait for a random amount of time, in the range from 0 to 2^n -1 units of time before attempting to retransmit the frame. Analyze the advantages of this design decision.

Clearly homework. Stop being lazy and google it.

I could not find out the answers by myself, so I asked help from this website( not for free). So I do not have any reasons to see the answer like that.
It's really more of an opinion anyway. I'll give you one advantage:
Increasing the time after each collision is a good idea so that the network doesn't get even more congested when there is a collision.

It helps reducing load on network, but the downside is that if the medium is heavy on load, there may be the possibility of complete transmission failure as well as the possibility of a random transmission time. So it is kind of impractical on heavily loaded networks where there will be more instances of transmission failing, and if transmission for a particular packet fails for more than the defined number of times, the packet is dropped.
