Year 10 OCR LAN Quiz

What are the three main types of LAN topologies?

• red, blue, and green

• up, down, and sideways

• square, triangle, and hexagon

• bus, ring, and star

Explain the star topology in a LAN network.

• All devices are connected to a wireless router.

• All devices are connected to each other in a circular fashion.

• All devices are connected to a mainframe computer.

• All devices are connected to a central hub or switch.

Describe the ring topology in a LAN network.

• Each device is connected to exactly two other devices

• Each device is connected to a central hub

• Each device is connected to only one other device

• Each device is connected to all other devices

What are the advantages of using a LAN?

• Faster communication, resource sharing, and cost-effectiveness

• Slower communication, limited resource sharing, and expensive

• No communication, no resource sharing, and cost-ineffective

• Unreliable communication, restricted resource sharing, and costly

How does LAN help in resource sharing?

• By increasing the cost of resources and making them less accessible

• By slowing down the network speed and causing congestion

• By restricting access to resources for all devices on the network

• By allowing multiple devices to be connected to a single network, enabling them to share resources such as files, printers, and internet access.

Explain how LAN facilitates communication within an organization.

• LAN only connects one device within an organization

• LAN connects multiple devices within a limited area, allowing for the sharing of resources and information.

• LAN does not allow for the sharing of resources and information

• LAN is used for long-distance communication within an organization

What are the disadvantages of LAN?

• High speed, wide coverage, and low cost.

• Unlimited geographical coverage, no security risks, and no need for additional hardware and maintenance.

• Limited geographical coverage, potential security risks, and the need for additional hardware and maintenance.

• No potential security risks, no need for additional hardware and maintenance, and easy to set up.

Discuss the security concerns related to LAN networks.

• LAN networks are completely secure and not susceptible to any security concerns.

• LAN networks are immune to unauthorized access and data interception.

• LAN networks are susceptible to security concerns such as unauthorized access, data interception, and malware attacks.

• LAN networks are only susceptible to security concerns related to physical damage, not cyber attacks.

What are the essential network components in a LAN?

• RAM, CPU, and hard drive

• NICs, switches, routers, and cables

• Satellite dish, modem, and fiber optic cable

• Keyboards, monitors, and printers

Explain the role of a router in a LAN network.

• It forwards data packets between different networks and provides security by filtering and controlling traffic.

• It is responsible for managing user access to the network

• It is used to store data in the network

• It is used to connect printers and other peripherals to the network
