Peripheral component interconnect(PCI) is a high band width processor independent bus.
It is the most widely used hardware interface for connecting the peripheral devices.
PCI-Express
They were known as an "expansion bus". So-called because the expansion cards with edge connectors, plugged directy into the bus board. (Today we would call it a motherboard) There were 3 bus standards: Industry Standard Architecture (ISA) Micro Channel Architecture (MCA) Extended Industry Standard (EISA) I hope that helps.

The PCI Express x16 is intended to ultimately replace the AGP bus along with the PCI-X and the Conventional PCI.
PCI express uses a serial bus

PCI Express 2.0 x 16 is the Fastest But PCI Express x16 is faster than AGP

Two other names for the system bus are: the front side bus and the memory bus.Answer; The PCI bus, and the PCI express bus
Doug Abbott has written: 'PCI bus demystified' -- subject(s): PCI bus (Computer bus)
It can have several buses, including the system bus, the PCI Express bus, the PCI bus, the AGP bus, and the outdated ISA bus.
A local bus is one which is integrated into the computer. Typically, this includes the Frontside Bus (or Hypertransport in AMD), the Memory Bus, the PCI bus, the PCI Express Bus (if present), the AGP Bus (if present), and onboard peripheral busses such as IDE, SATA, USB, IR, Firewire, and many others. Expansion buses are those which are not built in. For example, if you do not utilize onboard video, you would use a PCI, AGP, or PCI-E expansion bus to add video capabilities.
