Gce Model Questions Vol1 2021 Computer Studies Question 11
Practice objective / multiple choice question 11 from the 2021 Gce Model Questions Vol1 Computer Studies examination.
An 5 MB file is to be transmitted over a 2 Mbps link using a protocol that adds a 64‑byte header and a 16‑byte trailer to each packet. Each packet carries 1024 bytes of payload. The bit‑error rate of the link is \(10^{-6}\); a packet that contains any error must be retransmitted. Assuming errors in different bits are independent, estimate the expected transmission time (in seconds) for the whole file, ignoring propagation delay.
