Conventional PCI was created in 1993.

Conventional PCI now has four types of slots and six possible PCI card configurations to use these slots
The PCI Express x16 is intended to ultimately replace the AGP bus along with the PCI-X and the Conventional PCI.
PCI Express was created in 2004.
Equitable PCI Bank was created in 1938.
32 and 64 bit
4 Slot types and 6 possible configurations.
A conventional PCI bus (not PCI Express or such) at 64bit @ 66mhz has a max transfer rate of around 533MB/s. That being Megabyte, not bit. USB has a transfer rate of 12mb on regular and 480 on high-speed mode. That is megabit, which is much less then MB per second. PCI in this case, compared PURELY on speed, is much faster.
PCI, PCI-e, AGP
it will be written in the upper left hand corner of the cardYou can also tell by the location of the notches on the bottom of the card.A notch in a PCI slot distinguishes between a 5-V slot and a 3.3-V slot. A Universal PCI card can use either a 3.3-V or 5-V slot and contains both notches. Conventional PCI now has four types of slots and six possible PCI card configurations to use these slots.
PCI, PCI-X, PCIe, and mini PCI.
PCI-X is an extension to the original PCI slot. It uses a 64-bit data bus (most but not all PCI slots are 32-bit) and runs much faster than PCI (PCI runs at 33 or 66 MHz, PCI-X ranges from 66 MHz to 533 MHz). PCI cards can be used in a PCI-X slot, and most PCI-X cards will run in a PCI slot.PCI-E (PCI Express) is a totally different architecture. The connectors are similar, but PCI-E is a serialized bus, whereas PCI and PCI-X was parallelized. In PCI-E, there are fewer data paths but the paths run much faster. Think of it as the difference between a six lane highway with a speed limit of 35 MPH vs. a two lane highway with a speed limit of 75 MPH.
