Connectivity - Networks: How is data transmitted?

Connectivity - Networks: Data is transmitted through:

• Wires and wireless signals

• Only through wires

• Only through wireless signals

• None of the above

The meaning and significance of bandwidth is:

• The amount of data that can be transmitted in a fixed amount of time.

• The physical size of a network cable.

• The number of users connected to a network.

• The type of protocol used in communication.

Compare different types of cable, and the relative speeds of data transmission.

• Fiber optic cables transmit data faster than coaxial and twisted pair cables.

• Twisted pair cables are the fastest among all cable types.

• Coaxial cables are faster than fiber optic cables.

• All cable types transmit data at the same speed.

How do you calculate the time taken to download files of different sizes at different bandwidths?

• By dividing file size by bandwidth

• By multiplying file size and bandwidth

• By adding file size and bandwidth

• By subtracting bandwidth from file size

What is the definition of Bandwidth? Fill in the blank: Bandwidth is the amount of ______ that can be carried at a time.

• data

• time

• speed

• distance

What is one analogy for bandwidth?

• The speed of a car on a highway

• The amount of water that can flow through various sized pipes at any one time

• The height of a mountain

• The brightness of a light bulb

Look at the diagram and read the statement: 'Another analogy for bandwidth is a motorway – more lanes allow for more traffic to flow.' What does the number of lanes on the motorway represent in terms of bandwidth?

• The speed of each car

• The amount of data that can be sent at once

• The distance between the cars

• The color of the cars

According to the analogy in the image, more lanes on a motorway allow for ________ traffic to flow.

• more

• less

• slower

• no

What does Mbps stand for?

• Megabytes per second

• Megabits per second

• Millibits per second

• Microbytes per second

How many bits are there in a Megabit?

• 1,000 bits

• 1 million bits

• 8 million bits

• 1 billion bits
