Computer Networks

What the resources cover

This unit page sits in the Networks, the Internet and Cloud strand of Computing and ICT. The mind maps make up the largest share. Wired and Wireless networks links client-server and peer-to-peer networks, local area networks, wireless networking, protocols and layers, and data transmission. Other maps look at advantages and disadvantages of networks, such as sharing printers and files against the cost of extra hardware and wiring.

Protocols and layers

The map 7.1 Internet Protocols runs through Ethernet, TCP/IP, UDP, FTP, HTTP, Telnet and SSH, then sets out the protocol layers from physical up to application. Chapter 3: TCP/IP goes further, placing protocols such as DNS, DHCP, HTTPS and SNMP in their layers. Flashcard decks like Transport Layer and OSI Model cover the same ideas in small pieces.

Where to start

1. Open Wired and Wireless networks to see the whole topic on one map.
2. Take the Network Topology Quiz, which asks you to identify bus, ring and star layouts and name their drawbacks.
3. Move to the quiz 2.1.6 Networks for questions on LANs, WANs, network interface cards, routers and client-server setups.
4. Use the protocol maps once the basics feel steady.

Using quizzes and maps together

Read a map first, then close it and answer a quiz on the same idea. Wrong answers show which branch to reopen. Flashcards such as Topology Flash Cards and Bus Topology suit short, repeated practice on key terms. Many resources mention exams such as GCSE Computer Science, GCSE ICT, IGCSE, A-level and BTEC, so teachers can look for material that fits their course.

Your next step

Choose one map, work through a matching quiz, and then make a set of your own to fill any gaps you spot.
