The Video Electronics Standards Association (VESA) is an international body that has issued a number of standards, mostly relating to the functioning of video peripherals in IBM PC compatible computers.
Among VESA's standards:
VESA Local Bus (VLB), used at one time as a fast video bus (akin to the modern AGP).
VESA BIOS Extensions (VBE), used for enabling standard support for advanced video modes (at high resolutions and color depths)
