Answer:
1- Stop and wait protocol is also called as a one-bit sliding window protocol. The maximum size of the sender and receiver window is 1.
2- The maximum sender window size in go-back n is (2^n)-1, n is the sequence number.
= 2^5 -1
= 32-1
= 31
The maximum receiver window size is 1.
3- In selective repeat arq, the maximum window size is (2^n)/2 where n is sequence number, the sequence number here is 5.
so, 2^5/2
= 32/2
= 16
