Show answer & explanation
Correct answer: A
Answer: The computer bus provides the highest data rate to an individual device. Why: Internal computer buses (for example, the memory bus or PCI Express) are designed to move large volumes of data directly between the processor, memory, and peripherals with very high throughput. These internal links operate at much higher effective data rates than typical external communication systems. Telephone systems: built for voice/narrowband services, so data rates are low compared with internal bus speeds.
