TWO common types of network cable are:

• copper

• TSP

• fiber-optic

• RJ45

Multiple Choice

The advantage of copper over fiber-optic cable is:

• its easier to lay

• it lasts longer

• its cheaper

• its faster

Multiple Choice

The advantage of fiber-optic cable over copper cable is:

• it lasts longer

• its cheaper

• its faster

Multiple Choice

What is a network?

• A group of 1 or more devices which communicate

• A group of 2 or more devices which communicate

• When 2 or more computers are in the same building.

• A group of 3 or more devices which communicate

Some advantages of a WIRELESS network over a wired network are

• its faster

• its cheaper

• its more secure

• its easier to set up

Multiple Choice

A bus network is the appropriate topology for:

• A network that handles sensitive information

• A small office with a tight budget

• A large business

• A school

Multiple Choice

Its easier to to find a cable fault in a star network than a bus network because:

• Bus networks are less likely to have cable faults

• The server in a stat network plays a bleep code when a cable is damaged

• Each node in a star network has its own cable

Multiple Choice

A topology is:

• the arrangement of a network

• the height above sea level of each node on a network

• the arrangement of the natural and artificial physical features of a network

• derived from from the Greek words τόπος, 'network', and λόγος, 'study'

Multiple Choice

The advantage of a star network is

• It uses less cable than other topologies

• It requires no extra hardware such as hubs and switches

• It is easy to install and expand with extra nodes

• It is unaffected by a breakdown of the central computer

Multiple Choice

What type of topology is this?

• Mesh

• Ring

• Star

• Line

• Bus

Multiple Choice

Which network topology needs a switch or hub?

• Mesh

• Partial Mesh

• Star

• Bus

Multiple Choice

What does a Hub do?

• Once received sends data packets to all workstations

• Sends data packets only to intended recipient using MAC address

• Sends data packets through the internet

• Reduces network traffic

Multiple Choice

What is a characteristic of a LAN?

• Small geographical location such as a school or small office.
• Really cheap to set up.
• Uses less cables than a star.

Multiple Choice

"To share hardware, software and data" is the answer to the question ...

• Why do we network computers and other devices?
• Why do we use wi-fi all the time?
• Why is a network complicated?

Multiple Choice

What is bandwidth?

• The amount of data that can be carried at any one time.
• The overall amount of data I use in a month.
• The speed of my data per second to a friend and back.

Multiple Choice

What network topology is this ?

• BUS
• STAR
• RING

Multiple Choice

Which of these is an advantage of a Bus network?

• Easy to install

• Fast

• Good security

Multiple Choice

Which of these is an disadvantage of a Star network?

• Unreliable

• Needs extra hardware

• Slow

Multiple Choice

Which of these is an disadvantage of a Bus network?

• Expensive

• Needs extra hardware

• Slow

Multiple Choice

Which of these is an disadvantage of a Ring network?

• Unreliable

• Needs extra hardware

• Slow
