VLB or VL bus is short for VESA (Video Electronics Standards Association) local bus. Introduced by VESA in 1992, the VLB is a 32-bit computer bus that had direct access to the system memory at the speed of the processor. The 486 CPU (33/40 MHz) employed the VLB. VLB 2.0 was released in 1994, with a 64-bit bus, and a bus speed of 50 MHz. Unfortunately, the VLB relied heavily on the 486 processor. When the Pentium processor was introduced, manufacturers began switching to PCI.
