Q1. A sender is sending data using a window size of 4. If the sender sends 8 packets, how many ACKs are required?
Answer: 4
Explanation: In a sliding window protocol with a window size of 4, the sender can send 4 packets before needing an ACK. For 8 packets, 2 ACKs are needed to slide the window twice, but since the question likely implies cumulative ACKs, the number of ACKs required is 2 (for packets 4 and 8).
