The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of several slow Industry Standard Architecture (ISA. While PCI supports a wide range of expansions cards including NICs, modems, TV tuners and disk controllers, the standard is not as popular today for use as a graphic port because of its bandwidth constraints That role has by and large been taken. Comment. Its first version was the 8 bit bus and it ran at the speed of about 7 MHz. The MCA, EISA and VL buses. When the 80386DX was introduced in the mid-80s with its 32-bit data bus, IBM decided to create a bus to match this width.
