True or false, and briefly defend your response to the following questions: With a sender and receiver window size of 1, the alternating-bit protocol is the same as the SR protocol.
Computer Science Consider two hosts C & D connected by a point-to-point link with a data link rate of 10 Gb/s. The hosts are 2 km apart and the signal propagation speed is 2 × 108 m/s. Given the packet size is 500 bytes, how many packets can be in inflight from C to D?
True or untrue, and please include a short explanation for your choice: When both the sender's and receiver's window widths are 1, the alternating-bit protocol and the SR protocol are equivalent.
