The original 8-bit bus used in first-generation IBM PCs accepted only 8-bit expansion boards. It was superseded by the 16-bit AT bus
ISA Bus
was a bus originally used with the 486 computers and was limited in the number of slots to add on devices. Used for expansion cards such as video cards.
VL-Bus (VESA Local bus)
This bus is the present standard. It can transfer data 64-bit at a time with rates up to 66 MHz. The fastest of the present PIC is the PCI express (clock speeds reaching 133 MHz). uses either 32 or 64 bits of parallel data, depending on the version. So with each clock tick, 32 or 64 bit data is transferred over the bus. Transferring 64 bits at a time translates to a very large parallel bus, using a minimum of 64 lines in addition to all the required control and signal lines
PCI Bus
designed for video cards. A PCI bus is shared by devices connected to the bus. The transfer rate is reduced as more peripherals plugged to the PCI bus
AGP Bus
operated at 4.77 MHz
8 bit ISA
operated at 8 MHz
16 bit ISA
supports data transfer rates of 12 Mbps (12 million bits per second); can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards; are hot- pluggable and are also plug and play
