VL Bus

Updated: 04/26/2017 by Computer Hope

Alternatively abbreviated as VLB, VL Bus is short for VESA (Video Electronics Standards Association) Local Bus first 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, commonly the 486 CPU (33/40 MHz). VLB 2.0 was later released in 1994 and had a 64-bit bus and a bus speed of 50 MHz. Unfortunately, because the VLB heavily relied on the 486 processor, when the Pentium processor was introduced manufacturers began switching to PCI.
