What term describes the operational cost of sending data packets over a network?

• A. communication cost
• B. processing delay
• C. packet loss
• D. bandwidth utilization

Answer: (A)

Communication cost describes the resources required to transmit data across a network, including the time, overhead, energy, and other resources involved in sending packets. It captures the overall burden of moving information from sender to receiver, not just a single facet of the process.

Processing delay, for example, focuses on the time routers or devices take to handle a packet, which is only one piece of the total cost. Packet loss describes unsuccessful deliveries, which is about reliability rather than cost. Bandwidth utilization measures how much of the available link capacity is being used, which is related but doesn’t fully encompass the total operational burden of sending data.
