The number of bits conveyed per unit of time is called the bit rate.

The number of bits conveyed per unit of time is called the bit rate.

• A. Latency
• B. Bit rate
• C. Throughput
• D. Bandwidth

Answer: (B)

The main idea is data transfer speed measured as how many bits are moved in a given time, typically expressed in bits per second. That exact idea is captured by the term bit rate, which describes the rate at which bits are conveyed. It’s different from latency, which is the delay before data starts arriving; from throughput, which is the actual useful data delivered per unit time (and can be lower than the bit rate due to overhead); and from bandwidth, which is the maximum capacity of the channel.
