OCR A Level Network and Topologies Quiz

What are the two main types of networks?

• Ethernet and Token Ring

• WiFi and Bluetooth

• Intranet and Extranet

• LAN and WAN

Explain the difference between LAN and WAN.

• LAN and WAN are both wireless networks and have no geographical limitations.

• LAN and WAN are the same and can be used interchangeably.

• LAN connects devices over a large geographical area, while WAN connects devices within a small geographical area.

• LAN connects devices within a small geographical area, while WAN connects devices over a large geographical area.

What are the different network topologies?

• square

• triangle

• hexagon

• bus, star, ring, mesh, and hybrid

What is a star topology and how does it work?

• A star topology is a network topology where each device is connected to a central modem. All data passes through the modem, which manages the communication between devices.

• A star topology is a network topology where each device is connected to a central hub or switch. All data passes through the central hub, which manages the communication between devices.

• A star topology is a network topology where each device is connected to a central server. All data passes through the server, which manages the communication between devices.

• A star topology is a network topology where each device is connected to a central router. All data passes through the router, which manages the communication between devices.

How does a LAN differ from a WAN?

• LAN connects devices in a broad area, while WAN covers a limited area.

• LAN is used for wireless connections, while WAN is used for wired connections.

• LAN and WAN are the same and can be used interchangeably.

• LAN connects devices in a limited area, while WAN covers a broad area.

What are the advantages and disadvantages of a bus topology?

• Advantages: Easy to install and requires less cable. Disadvantages: Performance decreases as more devices are added, single point of failure.

• Advantages: Difficult to install and requires more cable. Disadvantages: Performance increases as more devices are added, multiple points of failure.

• Advantages: Requires specialized installation and more cable. Disadvantages: Performance remains constant regardless of the number of devices, no single point of failure.

• Advantages: Easy to install and requires less cable. Disadvantages: Performance increases as more devices are added, no single point of failure.

Explain the advantages of using a star topology for a network.

• Centralized management, easy troubleshooting, high performance, and scalability

• No management, no troubleshooting, poor performance, and no scalability

• Decentralized management, complex troubleshooting, average performance, and limited scalability

• Limited management, difficult troubleshooting, low performance, and lack of scalability

What is a mesh topology and how does it work?

• A mesh topology is a network topology where each device is connected to every other device. Data can take any possible path to reach its destination.

• A mesh topology is a network topology where each device is connected to a central hub. All data passes through the hub, which manages the communication between devices.

• A mesh topology is a network topology where each device is connected to a central server. All data passes through the server, which manages the communication between devices.

• A mesh topology is a network topology where each device is connected to a central router. All data passes through the router, which manages the communication between devices.

What is the difference between Ethernet and Token Ring?

• Ethernet and Token Ring are both wireless networks and have no geographical limitations.

• Ethernet is a network technology that uses a bus topology, while Token Ring uses a ring topology.

• Ethernet and Token Ring are the same and can be used interchangeably.

• Ethernet connects devices over a large geographical area, while Token Ring connects devices within a small geographical area.
