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)
VESA Display Data Channel (DDC), allowing monitors to identify themselves to the video boards they're attached to. The format of the actual identification data is however called EDID.
