What bandwidth measurement unit corresponds to bits per second?

The correct choice is bits per second (bps), which serves as the fundamental unit for measuring bandwidth in networking and data transmission. Bandwidth is the capacity of a network to transmit data over a specific time period, and bits per second offers a straightforward representation of this capacity.

While other options like kbps (kilobits per second), Mbps (megabits per second), and Gbps (gigabits per second) are indeed valid units of bandwidth, they are derived from bps and represent larger scale measurements. Specifically, 1 kbps equals 1,000 bits per second, 1 Mbps equals 1,000,000 bits per second, and 1 Gbps equals 1,000,000,000 bits per second. Therefore, bps is the base unit, from which these larger units are derived, making it the most fundamental choice in this context.
