Which of the following PCI system buses has a maximum data transfer rate of 264 Mbps? (Choose all that apply)
A.
PCI 32/33
B.
PCI 32/66
C.
PCI 64/33
D.
PCI 64/66
E.
PCIe 64/66
Explanation:
The data transfer rate of a PCI bus can be calculated by multiplying the PCI bus width by the PCI bus speed and dividing the result by eight to convert it from Megabits per second (Mbps) to Mega bytes per second (MBps). Thus both PCI 32/66 and PCI 64/33 have amaximum data transfer rate of approximately 264 Mbps as 32 66 / 8 = 264 and 64 33 / 8 = 264.
Incorrect Answers:
A: PCI 32/33 has a maximum data transfer rate of approximately 132 Mbps as 32 33 / 8 = 132.
D, E: Both PCI 64/66 and PCIe 64/66 have a maximum data transfer rate of approximately 528 Mbps as 64 66 / 8 = 528.
