Network latency concept – UGC NET Question

Latency represents the delay between sending a request and receiving a response, which users perceive as responsiveness of a system. It is influenced by factors such as distance, routing and processing delays in intermediate devices. Low latency is especially important for interactive applications like video conferencing and online gaming. Hence, the timing measure in the stem is known as latency.

Option A:
Option A, bandwidth, deals with the capacity of a link rather than the time a packet takes to traverse it, so it is not an indicator of delay.

Option B:
Option B, frequency, relates to the number of cycles per second in a signal and is associated with physical characteristics rather than end to end transmission time.

Option C:
Option C, jitter, is the variability in latency and describes how much the delay fluctuates rather than the delay itself.

Option D:
Option D is correct because latency is defined as the time interval between an event at the sender and the corresponding event at the receiver, which matches the description in the question.
