What is the amount of data transmitted on a transmission medium over a period of time?

The amount of data transmitted on a transmission medium over a period of time is referred to as bandwidth. It is typically measured in bits per second (bps) and indicates the maximum data transfer rate of that medium. Higher bandwidth allows for more data to be transmitted concurrently, improving the efficiency and speed of communication. Factors such as network congestion, signal quality, and technology used can affect the actual data transmission rate.
