Question 1: Define a Local Area Network (LAN) and give two examples of where it might be used.

Answer: A LAN is a network that connects computers within a small geographical area, like a school or office building. Examples include the network within a school’s computer lab and an office’s internal network.

Question 2: List three common components found in most computer networks.

Answer: Router, switch, and network cables (Ethernet cables).

Question 1: Look at the diagram below (diagram not included here). Identify which device is a 'Switch' and explain its role in a network.

Answer: The switch is the device that connects multiple computers within a network and manages data traffic between them, ensuring data is sent to the correct device.

Question 2: You are setting up a small office network. Which device would you use to connect all computers to the internet?

Answer: A router.

Question 1: Compare a Wide Area Network (WAN) and a Local Area Network (LAN). Mention one advantage of each.

Answer: A LAN connects devices within a small area and offers high data transfer speeds. An advantage is quick data sharing within a building. A WAN covers larger areas, like across cities or countries, and its advantage is enabling long-distance communication.
