Answer
Bandwidth refers to the total amount of data that can be sent and received over a network in a specified period of time. In this context, it indicates the capacity of a network connection to transmit information, with higher values representing greater capability.

Answer
Fibre-optic cables have low or no signal degradation over long distances, meaning they can maintain quality without losing data integrity.
They are less susceptible to electromagnetic interference (EMI), making them a more secure option for data transmission.
Step 4

Answer
UTP cables are often less prone to interference, providing a more stable connection.
They do not experience slowdowns when multiple users access the network simultaneously.

Answer
A Network Interface Card (NIC) facilitates communication between a computer and a network medium. It allows devices to connect to the network and can encode and decode signals to transmit data effectively.
