Network Types & Performance Quiz

1. Describe the difference between a LAN and WAN.

• A LAN is used for personal devices, while a WAN is used for city-wide networks.

• A LAN uses third-party communication channels, while a WAN does not.

• A LAN covers a small geographical area, while a WAN covers a large area.

• A LAN covers a large geographical area, while a WAN covers a small area.

2. Give an example of how a LAN could be used.

• Connecting computers in a school.

• Connecting personal devices like smartphones.

• Connecting computers across different countries.

• Connecting computers in a city.

3. Give an example of how a WAN could be used.

• Connecting personal devices like smartphones.

• Connecting computers in a school.

• Connecting computers in a single office.

• Connecting computers across different countries.

4. Describe how peer-to-peer networks function.

• Data is shared directly between systems without a central server.

• Clients make requests to a server, which manages and responds to them.

• Data is transferred through a central hub or switch.

• Data packets are sent along the quickest path from node to node.

5. Describe how client-server networks function.

• Data is transferred through a central hub or switch.

• Data packets are sent along the quickest path from node to node.

• Clients make requests to a server, which manages and responds to them.

• Data is shared directly between systems without a central server.

6. State one use for a peer-to-peer network.

• Managing network security and backups.

• Controlling network traffic congestion.

• Handling millions of requests per second.

• Quickly sharing files between systems.

7. State one use for a client-server network.

• Connecting personal devices like smartphones.

• Quickly sharing files between systems.

• Handling millions of requests per second.

• Connecting computers in a single office.

8. Which of the following is an advantage of a star topology?

• Less expensive to install and maintain.

• No central device is required.

• Data packets can take alternative routes if one path fails.

• Improved security as data packets are sent directly to the hub.

9. Which of the following is a disadvantage of a mesh topology?

• If the central system fails, the whole network fails.

• System failures of attached computers cause complete network failure.

• Requires a large amount of cables, making it expensive.

• Data packets are sent directly to and from the hub.

10. State one factor that could affect the performance of a network.

• The color of the cables used.

• The type of operating system installed.

• The bandwidth available.

• The brand of the computers connected.
