What does the term "bandwidth" refer to in network technology?

In network technology, "bandwidth" specifically refers to the maximum rate of data transfer that can occur over a network connection. This measurement is typically expressed in bits per second (bps) and indicates the capacity of the network to transmit data at any given moment. Higher bandwidth allows for more data to be transferred simultaneously, leading to faster internet speeds and improved performance for applications that require large amounts of data transfer, such as streaming video, online gaming, and large file downloads.

While physical distance, the number of devices, and data storage are important aspects of network performance and design, they do not define what bandwidth is. Bandwidth focuses purely on the rate of data transfer capability of the network infrastructure, which is why it is considered the correct answer in this context.
