What does the term 'bandwidth' refer to?

The term 'bandwidth' specifically refers to the maximum data transfer rate of a network or internet connection. This measurement indicates how much data can be transmitted over a connection in a given amount of time, typically expressed in bits per second (bps). Understanding bandwidth is important because it directly impacts how quickly data can be downloaded or uploaded, and how many devices can effectively use the connection simultaneously without degrading performance.

In contrast, other choices describe related but distinct concepts. The average speed of a network connection represents the typical speed experienced by users, which can vary based on factors like congestion or network conditions, and does not necessarily equal the maximum bandwidth. The total amount of data sent over time can refer to cumulative data transfer but does not define bandwidth itself. Minimum signal strength pertains to the minimum level of signal required for reliable data transmission, which is not a measure of bandwidth.
