The VESA Local Bus (VLB) is a high-speed interface standard designed for connecting peripheral devices to a computer's motherboard. Introduced in the early 1990s, it allows for faster data transfer rates compared to older bus standards, making it suitable for graphics cards and other high-performance components. VLB operates at a clock speed of 33 MHz and supports 32-bit data transfers. It was primarily used in Intel 486-based systems, providing a significant performance boost for applications requiring quick access to memory and data. However, it was eventually replaced by more advanced standards like PCI (Peripheral Component Interconnect).
