An agricultural research facility is setting up a localized network to connect several environmental sensors. The network administrator decides to implement a star network topology, as illustrated in the diagram below:

Explain how the devices are connected in a star network topology and describe how the failure of a single connection cable affects the rest of the network.
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.
