The amount of time between when the source sends information and the target receives it is known as:

Bandwidth is the maximum data transfer capacity of a link measured in bits per second, representing how much data can travel through the link, not how long the trip takes.

Latency measures the one-way or round-trip delay a packet experiences as it travels from sender to receiver, encompassing propagation delay, transmission delay, and queuing delay. It is the key metric for assessing network responsiveness and is distinct from capacity-based measures such as bandwidth or throughput.

Throughput is the actual measured rate of successful data delivery across a network over a period of time, not the time elapsed for a single transmission to arrive.

Flow control is a mechanism used to regulate the transmission rate between sender and receiver to prevent buffer overflow, and is a process, not a time measurement.
