VL bus
Updated: 04/26/2017 by Computer Hope
VLB or VL bus is short for VESA 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 (central processing unit) (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 (peripheral component interconnect).
