The A+ examination requires you to understand bus architectures. As you work you will be installing a number of network cards, sound cards, and video cards. Which of the following is a downfall of Peripheral Component Interconnect? a. It can only support three devices at a time b. It has a fixed width of 64 bits c. It has a fixed width of 32 bits d. It can only support one device at a time
C. 32 bits. Peripheral Component Interconnect (PCI) has a fixed width of 32 bits and can only handle five devices at a time. PCI-X is 64 bits and provides more bandwidth.
