What is BUS speed?

What is BUS speed?

• A. The rate of communication speed between microprocessor and RAM.
• B. The clock frequency of the CPU.
• C. The speed of network bus to the motherboard chipset.
• D. The transfer rate from CPU to hard drive.

Answer: (A)

Bus speed describes how fast data moves across the system bus—the communication path that connects the CPU with memory and other core components on the motherboard. The key idea is the rate at which the processor can exchange information with RAM, since memory access is a fundamental part of how the CPU operates. This directly impacts how quickly instructions and data can be fetched and stored, which is why the communication rate between the microprocessor and RAM best captures what the bus speed measures. The CPU’s clock frequency is its own speed, not the bus. The “network bus to the chipset” isn’t the CPU–RAM path, and the transfer rate to a hard drive involves storage interfaces, not the core system bus.
