Network bandwidth definition – UGC NET Question

Bandwidth describes the capacity of a communication medium to carry data per unit time, often measured in bits per second. Higher bandwidth allows more information to pass through the channel simultaneously, supporting faster downloads and better quality multimedia streams. It is a key parameter when designing or selecting network connections. Thus, the quantity described in the question is bandwidth.

Option A:
Option A, latency, indicates the delay experienced in transmission and is about time rather than capacity, so it does not reflect maximum data rate.

Option B:
Option B, throughput, measures the actual data transfer achieved in practice, which can be lower than the maximum possible rate due to various overheads and losses, and is therefore conceptually distinct.

Option C:
Option C is correct because in ICT terminology bandwidth consistently denotes the theoretical or allocated maximum data carrying capacity of a link or channel.

Option D:
Option D, jitter, refers to variation in delay over time and affects quality of real time applications but does not specify a maximum rate.
