VESA - Video Electronics Standard Association (Created by a group of manufactures)
VL Bus - Enhanced Video Electronics Standard Association Local Bus
PCI - Peripherals Component Interconnect (Created by the Intel Corporation)
About the VESA + VL bus
1. Has a clock speed of 33 MHz - 66MHz(Pentium)
2. The PCI bus has a special chip set which allows more sophisticated control over the devices.
3. The PCI Bus can support many more devices then VESA + VL Bus.
4. A greater variety of expansion cards can be attached.
5. Supports a 64 bit extension for the Pentium processor along with a clock speed of 66MHz.
6. PCI is used in other computer architectures such as the Macintosh computers.

About the VESA + VL bus
1. Has a clock speed limit of 33 MHz.
2. Limited to a 32-Bit wide word length (32 data lines).
3. Cannot take advantage of the Pentium’s 64 bit architecture.
4. Restricted on the number of devices which can be connected ( 1 or 2 devices).
