City Guilds Model Questions Vol1 2025 Information Technology Question 1
Practice objective / multiple choice question 1 from the 2025 City Guilds Model Questions Vol1 Information Technology examination.
A 12 MB file is to be transferred over a network using TCP. Each TCP segment carries a payload of 1460 bytes, and each IP packet adds a 20‑byte IP header and a 20‑byte TCP header. The link has a bandwidth of 100 Mbps and a round‑trip time (RTT) of 80 ms. Assuming the TCP window size is large enough to keep the link fully utilized and that the transmission starts with a three‑way handshake (which adds one RTT) and ends with a four‑way termination (adds another RTT), calculate the total time required to transfer the file, ignoring any retransmissions. Give your answer in seconds to two decimal places.
