Which term is used for data transfer rates such as bps, Kbps, Mbps, Gbps, or Tbps?

• A. Throughput unit
• B. Processing speed
• C. Storage unit
• D. Bandwidth

Answer: (A)

Data transfer rate is about how much data moves per second, expressed in bits per second with prefixes like Kbps, Mbps, Gbps, or Tbps. The term that describes this rate is throughput, which measures the actual data flow achieved. Bandwidth, by contrast, refers to the maximum capacity of a link, not the realized rate. So the unit used to express these data transfer rates is a throughput unit, which is why that option is the best choice.
