Final answer:
Bandwidth refers to the capacity of a network to transfer data, measured in bits per second, and not the number of connected devices.
Step-by-step explanation:
The term bandwidth does not describe the number of devices connected to a network. Instead, it refers to the capacity of a network to transfer data in a given amount of time, typically measured in bits per second (bps). For instance, a bandwidth of 75 Mbps (megabits per second) means that up to 75 million bits can be transmitted each second. Bandwidth is crucial for determining how efficiently data can move through the network. It is a key factor in the performance of Internet connections, especially for data-intensive activities like streaming video or online gaming.
