Which common bus specification provides the fastest data transfer rate?

  • A.VL bus
  • B.ISA
  • C.PCI
  • D.All of the above

Answer: C

Correct answer: PCI

PCI runs at 33 MHz and 32 bits, giving about 133 MB/s, against the VL bus's dependence on the processor bus and ISA's 8 MHz. It is also processor-independent, which is why it outlasted VL.
