Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The vulnerable time for CSMA is the ____ propagation time.
A
the same as
B
two times
C
three times
D
None of these
Explanation: 

Detailed explanation-1: -In the CSMA vulnerable time is considered as the propagation time and Tp is used to denote it. Generally, it is the time taken by the data frame to reach from one end of the channel to another end. When two stations send the data simultaneously then it will result in a collision in the network.

Detailed explanation-2: -Vulnerable time in ALOHA depends on the frame transmission time (Tfr), but in CSMA it depends on frame propagation time. Save this question.

Detailed explanation-3: -The duration depends on the IEEE-802.11 standard and is between 10 µs and 16 µs.

Detailed explanation-4: -CSMA stands for carrier sense multiple access, which means that every node on the network must monitor the bus for a period of no activity before trying to send a message on that bus (carrier sense).
