Answer
Bandwidth refers to the total amount of data that can be sent and received in a network within a specific time frame. It measures the network's capacity and is typically quantified in bits per second.

Answer
Fibre-optic cables have low or no signal degradation over distance, resulting in minimal loss of signal quality.
They are immune to electromagnetic interference (EMI), making them more secure and reliable.

Answer
UTP cables are less prone to interference, which can lead to a more stable connection.
They do not suffer from the issues of signal strength variances associated with Wi-Fi, providing consistent performance across the network.
