An autonomous deep-sea submersible transmits real-time sensor telemetry to a surface research vessel over a TCP connection. Due to acoustic underwater interference, the data packets often arrive out of sequence, and some packets fail to arrive entirely.
Explain how the Transport layer at the receiving station on the research vessel reconstructs the continuous stream of telemetry data from these received packets, and how it handles packets that have been lost in transit.
Practise Edexcel GCSE Computer Science Networks with exam-style questions for GCSE Computer Science. 100 questions covering Why computers are networked, Types of network (LAN, WAN), Structure of the internet, Wired and wireless connectivity performance, Network speeds and transmission calculations, Network and email protocols, The 4-layer TCP/IP model, and Network topologies (bus, star, mesh), matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
