WJEC GCSE Unit 1 Networks

Which of the following best describes the difference between a Wide Area Network (WAN) and a Local Area Network (LAN)?

• WAN is sited on a single site, while LAN is sited on multiple sites.

• LAN is sited on a single site, while WAN is sited on multiple sites.

• Both WAN and LAN are sited on multiple sites.

• Both WAN and LAN are sited on a single site.

What is the primary function of a switch in a network?

• It copies all packets of data to all devices on the network.

• It stores the addresses of computers on the network and transfers data between devices.

• It joins together two networks that use different base protocols.

• It analyses each packet of data and sends it to the computer it was intended for.

Which device copies all packets of data to all devices on the network?

• Switch

• Hub

• Router

• Gateway

What is the role of a router in a network?

• It joins together two networks that use different base protocols.

• It stores the addresses of computers on the network and transfers data between devices.

• It analyses each packet of data and sends it to the computer it was intended for.

• It copies all packets of data to all devices on the network.

Which device joins together two networks that use different base protocols?

• Switch

• Hub

• Gateway

• Bridge

What is the function of a bridge in a network?

• It joins together two networks that use different base protocols.

• It joins together two networks that use the same base protocols.

• It stores the addresses of computers on the network and transfers data between devices.

• It copies all packets of data to all devices on the network.

Which type of network is typically used within a very small area, such as a single room?

• Personal Area Network (PAN)

• Metropolitan Area Network (MAN)

• Virtual Private Network (VPN)

• Wide Area Network (WAN)

Which type of network allows people to log into a network remotely and access its resources?

• Personal Area Network (PAN)

• Metropolitan Area Network (MAN)

• Virtual Private Network (VPN)

• Local Area Network (LAN)

Which network topology connects each node to exactly two other nodes, providing a single pathway for signals through each node?

• Ring

• Bus

• Star

• Mesh

What is a disadvantage of the bus topology?

• High transfer speeds

• Expensive to set up

• Can fail if one node fails

• Can be slow under heavy traffic due to collisions
