Bandwidth is the maximum data transfer rate of a network.

Bandwidth is the maximum data transfer rate of a network.

• A. The number of devices connected to a network.
• B. The security level of the network.
• C. The physical length of the network cable.
• D. The maximum data transfer rate of a network.

Answer: (D)

Bandwidth describes the capacity of a network link to carry data, i.e., how fast data can move across the link per second. It’s the maximum data transfer rate the network can sustain, usually measured in bits per second. The number of devices connected doesn’t set that limit; it affects how much data is being used, not the top speed of the link. Security level is about protection, not speed. The physical length of the cable can impact signal quality and practical speeds in some cases, but bandwidth itself is defined as the maximum rate at which data can be transferred. So the option that defines bandwidth as the maximum data transfer rate is the correct one.
