Network Essentials: Computer Networks and Topologies

What is a LAN?

• A network spanning a large area, like a country or continent

• A network confined to a small area, like a building or campus

• A network connecting two computers

• A network connecting devices linearly

What is a characteristic of a WAN?

• Confined to one building

• High-speed bandwidth

• Spans a large area

• Owned by one organization

What happens if the central hub fails in a star network topology?

• Only the connected computer will fail

• The entire network will fail

• Only the peripheral devices fail

• The network will bypass the hub

Which network topology relies on a central device?

• Star

• Mesh

• Ring

• Bus

What is the main advantage of a mesh network topology?

• Easy to set up

• Cost-effective

• Less likely to have network failure

• Uses less cabling

Which device connects multiple networks and routes data packets?

• Switch

• Router

• Hub

• Repeater

What does a network switch do?

• Amplifies the signal over the same network

• Connects multiple devices on a single network and filters data packets based on MAC addresses

• Connects different networks and manages the traffic between them

• Regenerates and strengthens the signal in a network

What is the main role of a wireless access point in a network?

• To connect wireless devices to a wired network

• To amplify the network signal

• To connect and manage traffic between networks

• To strengthen the network signal

What is the main disadvantage of a wireless network compared to a wired one?

• Higher cost

• Lower speed

• Less secure

• Harder to set up
