What is a Local Area Network (LAN)?

• A network that spans a large geographical area

• A network within a single building or close geographical area

• A network that connects computers across the world

• A network that only exists in the cloud

In a LAN, what is the role of a router?

• To connect the LAN to external networks

• To spread viruses throughout the network

• To slow down access to external networks

• To monitor data traffic within the network

How can viruses spread more easily in a LAN?

• Through shared resources

• Through the main server

• Through external networks

• Through standalone computers

Which of the following is an advantage of using LANs?

• Easier spread of viruses

• Slower access to external networks

• Sharing of resources such as hardware and software

• Increased security risk

What happens if the main server in a LAN breaks down?

• The network will function more efficiently

• The network will no longer function properly

• The network will be free from viruses

• The network will have faster access to external networks

What is typically shared among computers in a LAN?

• Hardware resources like printers and scanners

• Personal files of the users

• The operating system

• The computer’s power supply

How does a LAN allow easy communication between its users?

• Through postal mail

• Through telephone calls

• Through simple text messaging between computers on the network

• Through face-to-face meetings

Who ensures the security and use of the LAN is constantly monitored?

• The router

• The main server

• The network administrator

• • The internet service provider

Why might there be queues for shared resources in a LAN?

• Because of slow internet speed

• Because of power outages

• Because multiple users might need to use the same resource at the same time

• Because of software updates

Why is there an increased security risk in a LAN compared to stand-alone computers?

• Because LANs are always connected to the internet

• Because LANs use outdated security protocols

• Because if one computer in the network gets compromised, it can affect others

• Because stand-alone computers have stronger firewalls
