Gce Model Questions Vol1 2025 Computer Studies Question 11
Practice objective / multiple choice question 11 from the 2025 Gce Model Questions Vol1 Computer Studies examination.
A file of size \(12.5\text{ MB}\) is to be transmitted using a stop‑and‑wait protocol over two serial links in series. The first link has a bandwidth of \(5\text{ Mbps}\) and a latency of \(20\text{ ms}\); the second link has a bandwidth of \(2\text{ Mbps}\) and a latency of \(50\text{ ms}\). Each data packet carries \(1500\) bytes of payload (ignore headers) and acknowledgements are negligible in size. Assuming the sender must wait for an acknowledgement before sending the next packet, calculate the total time required to send the entire file, giving your answer in minutes to one decimal place.
