Demonstrate understanding of local area network technologies
Demonstrate understanding of local area network technologies
This standard asks you to demonstrate understanding of how local area networks (LANs) work — the systems that connect computers and devices in schools, offices, or homes. You need to understand the basic components (like switches and cables), explain why particular technologies are used, describe how devices communicate with each other, and explain how the network controls that communication.
You describe the main LAN components, explain basic networking concepts, and describe why some technologies are used and how Ethernet access control works.
You compare different types of LANs (peer-to-peer vs client/server), explain the TCP/IP layers and how they work in a LAN, and discuss the advantages and disadvantages of different cable, fibre, and wireless technologies.
You discuss IP addressing schemas in detail including the real consequences of static versus dynamic addresses, and explain how Ethernet's access control method actually manages and controls traffic on the network.
