Y10 Computer Science: Wired vs Wireless

What is the primary difference between wired and wireless data transmission?

• Wired uses radio waves, wireless uses physical cables.

• Wired involves a physical connection, wireless uses radio waves.

• Wired is always faster, wireless is always slower.

• Wired is less reliable, wireless is more reliable.

How do fibre-optic cables generally compare to copper cables in terms of bandwidth and latency?

• Fibre-optic cables have lower bandwidth and higher latency.

• Fibre-optic cables have higher bandwidth and higher latency.

• Fibre-optic cables have lower bandwidth and lower latency.

• Fibre-optic cables have higher bandwidth and lower latency.

Are you enjoying the video lesson?

• Yes

• No

What effect do repeater nodes have on data transmission latency?

• They eliminate latency by amplifying the signal.

• They reduce latency by shortening the transmission path.

• They introduce additional latency due to processing and retransmission.

• They only affect bandwidth, not latency.

What are the typical range and bandwidth of Fibre-optic cables compared to Copper (UTP Cat6) cables?

• Fibre-optic cables have a shorter range (100m) and lower bandwidth (1Gbps) than Copper (UTP Cat6) cables.

• Fibre-optic cables have a similar range (100m) but higher bandwidth (100Gbps) than Copper (UTP Cat6) cables.

• Fibre-optic cables have a much longer range (2km) and higher bandwidth (100Gbps) than Copper (UTP Cat6) cables.

• Fibre-optic cables have a longer range (2km) but lower bandwidth (10Gbps) than Copper (UTP Cat6) cables.

What factor primarily limits the maximum download speed of a broadband connection?

• The speed of the fastest component in the network.

• The slowest component in the entire connection chain.

• The total number of devices connected to the network.

• The type of operating system used by the connected devices.
