Question 1: Define a Local Area Network (LAN) and a Wide Area Network (WAN). Highlight the main difference between them.

Answer: A LAN is a network that connects computers within a small area such as a building or campus, whereas a WAN covers a much larger geographical area, often connecting multiple LANs over long distances. The main difference is the size and scope of the network.

Question 2: List two common examples of LANs and two common examples of WANs in everyday life.

Answer: LAN examples: School computer network, home Wi-Fi network. WAN examples: The internet, a corporate global network.

Question 3: Describe one advantage of using a LAN over a WAN.

Answer: A LAN usually has faster data transfer speeds and lower latency because it covers a smaller area and has fewer connected devices.

Question 4: Explain why the internet is considered a WAN.

Answer: Because it connects computers and networks across the world over large distances, making it a Wide Area Network.

Question 5: Complete the following truth table for an AND logic gate:

Answer: | Input A | Input B | Output | |---------|---------|--------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 |

Question 6: Complete the truth table for an OR logic gate:

Answer: | Input A | Input B | Output | |---------|---------|--------| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 |

Question 7: Draw a simple diagram to show how two LANs can be connected to form a larger network. Label each LAN and the connection between them. (Draw a rough sketch in the space below.)

Answer: A correct sketch would show two separate circles or rectangles labeled 'LAN 1' and 'LAN 2', connected by a line labeled 'Router' or 'Bridge', indicating they are connected through a network device.

Question 8: Sketch a basic network setup that includes a computer, a router, and a Wi-Fi connection to the internet. Label each component clearly.

Answer: A correct sketch would show a computer connected wirelessly to a router, with the router connected to the internet (depicted as a cloud or similar symbol).

Question 9: Explain one advantage of using a WAN for a large company with multiple offices in different countries.

Answer: A WAN allows the company to connect its offices over long distances, enabling efficient communication and data sharing across different locations.

Question 10: Describe a situation where a local network (LAN) would be preferred over a wide network (WAN).

Answer: A school computer lab where students share resources and files would benefit from a LAN due to its speed and security within a small area.
