Computer Networks

What is the main purpose of a computer network?

• To increase computer speed

• To install software

• To connect devices for data and resource sharing

• To enhance screen resolution

Which network type typically connects computers in a single building?

• WAN

• MAN

• LAN

• PAN

A network that spans across a city is called a:

• WAN

• LAN

• PAN

• MAN

WAN stands for:

• Wired Access Network

• Wide Area Network

• Wireless Active Network

• Web Area Network

The physical layout of network devices is known as:

• Network mapping

• Protocol design

• Network topology

• Device architecture

In which topology are all devices connected to a single backbone cable?

• Ring

• Mesh

• Star

• Bus

Which topology uses a central hub to connect all devices?

• Ring

• Star

• Mesh

• Bus

What is a key disadvantage of Ring topology?

• Easy to install

• Central hub failure brings down the network

• One node failure can affect the entire network

• Requires less cabling

Which topology is the most fault-tolerant but costly?

• Star

• Bus

• Hybrid

• Mesh

A combination of two or more topologies is called:

• Star topology

• Hybrid topology

• Mesh topology

• Complex topology
