Bandwidth in a network refers to:
A. How much data can be transferred per unit of time✓ 答案
B. The colour of the physical cable only
C. The processor's clock speed only

Bandwidth is a capacity measure in bits per second, so it limits throughput. Delay, or latency, is a separate measure of how long a packet takes, and a link can have plenty of bandwidth and still feel slow.
