What does Bandwidth refer to in web terms?

Bandwidth in web terms refers specifically to the amount of data transmitted over a network in a given time. This measurement is often represented in bits per second (bps) and reflects how much data can be sent from one point to another within a certain period. It provides insight into the maximum rate of data transfer for a network connection, allowing users to gauge the effectiveness and speed of their internet service.

While speed of data transfer relates to how quickly data can be sent or received (which is important in networking contexts), bandwidth focuses on the volume of data that can be moved, making option B the more precise definition.

The size of files stored on a server pertains to disk space rather than bandwidth, and the capacity of a client's device does not directly involve the speed or volume of data transmitted over a network. Both of these aspects are crucial in the overall performance of web applications and user experience but do not define bandwidth itself.
