Which of the following describes the amount of data that can be sent across a link in a given time?

Network bandwidth refers to the maximum data transfer rate over a network connection in a given period, typically measured in bits per second (bps). It represents the capacity of the link to carry information.

Network QoS (Quality of Service) involves technologies that prioritize network traffic to ensure performance for specific applications, not the total data amount that can be sent.

Network latency is the time delay before data transfer begins following a command, measuring time rather than the volume of data.

Network speed is a more general and less precise term often used interchangeably with bandwidth, but bandwidth more accurately defines the 'amount of data' capacity.
