CompTIA A+ 220-701: 1.2 – Bus Architectures and Expansion Slots

| January 28, 2010


An important consideration of the very first IBM personal computer was including standardized expansion slots so the end-user could customize their system. In this video, you’ll learn about bus architectures and expansion slots, including PCI, PCI Express, AGP, and CardBus.

    Professor, do all 32bit cards support 3.3v and 5v?

    • There are some 32-bit cards that only support 3.3V, others that support only 5V, and some that will support both 3.3V and 5V.nnhttp://en.wikipedia.org/wiki/File:PCI_Keying.png

    Since the throughput calculations come up with numbers in the millions then have to convert that number from bits to megabytes, its easier to just multiply width by clock speed in MHz then divide that by 8.nnExample: u00a016bit bus X 7MHz clock = 112 /8 = u00a014 MB per second

    The original PC used the PC/XT bus if my memory serves me correct, not an ISA. The ISA came afterwards.
