L7 What is the internet

The ??? the bandwidth, the more data the transmission media can transmit at once.

• Lower

• Higher

• Smaller

• Lesser

??? is a measure of how much data can be transferred in a specific amount of time.

• Latency

• Frequency

• Bandwidth

• Range

A typical bandwidth for fibre optics is ??? Gbps.

• Five

• Ten

• Twenty

• Fifty

Data travels across a network using signals. These can be light ???, radio waves, or electrical ???.

• Pulses

• Currents

• Waves

• Beams

Each type of transmission media has a maximum distance that the signal can travel before the signal quality is lost. This maximum distance is called the ???.

• Length

• Width

• Range

• Span

The ??? connected to a network will affect the network performance. This is because each device will take a share of the bandwidth available and the network traffic.

• Type of cables

• Number of devices

• Speed of connection

• Quality of service

Copper cable has a range of ??? metres.

• Fifty

• Hundred

• Two hundred

• Five hundred

??? is the delay from the time a signal is sent to when it is received.

• Bandwidth

• Frequency

• Latency

• Range
