Network Topologies and Key Network Components

What is a network topology?

• The physical or logical layout of a network

• A type of internet service provider

• A programming language for networking

• A security feature in routers

Which of the following is NOT a common network topology?

• Star

• Tree

• Ring

• Hexagon

In a star topology, all devices connect to:

• A single backbone cable

• A central hub or switch

• Each other directly

• A wireless signal only

What is the main advantage of a star topology?

• It is the cheapest to set up

• It remains functional if one device fails

• It doesn’t require a central device

• It requires fewer cables than a bus topology

What is a major disadvantage of a bus topology?

• It requires a lot of cables

• If the central cable fails, the entire network goes down

• It is the most expensive topology

• It is only used in small networks

In which topology is data sent in one direction around a loop?

• Star

• Bus

• Ring

• Mesh

What is a key benefit of a mesh topology?

• It has a simple design and is easy to set up

• It requires only one connection per device

• It provides multiple paths for data, making it more reliable

• It doesn’t require any network hardware

What does a router do in a network?

• Connects devices within a local network

• Directs data between different networks

• Stores files for the network

• Acts as a firewall

What is the purpose of a switch in a network?

• To connect devices within a local network and direct data between them

• To connect different networks together

• To provide wireless connectivity

• To act as a backup power source

Which device allows wireless devices to connect to a network?

• Router

• Switch

• Access Point

• Modem
