What does bandwidth refer to in the context of networking?

Bandwidth in the context of networking specifically refers to the capacity for data transfer over a given time, usually measured in bits per second (bps). It indicates how much data can be transmitted through the network at any given moment. Higher bandwidth allows more data to be sent simultaneously, which is essential for activities such as streaming video, downloading files, or online gaming where large amounts of data need to be transferred quickly.

Understanding bandwidth is crucial, especially when considering network performance, as a higher bandwidth generally leads to faster and more efficient data transmission. This is why choosing the correct answer focuses on the ability to handle data transfer rates, which directly affects user experience and network efficiency.
