ISA (Industry Standard Architecture)
The Industry Standard Architecture design is found in the original IBM PC for the slots on the motherboard that allowed additional hardware to be connected to the computer's motherboard. An 8-bit, 8.33 MHz expansion bus was designed by IBM for its AT computer and released to the public domain. An improved 16-bit bus was also released to the public domain. Various other designs such as IBM's MicroChannel and EISA bus tried to improve on the design without much popularity. ISA only supports 8- and 16-bit data paths, so 32-bit alternatives such as PCI and AGP have become popular. Although ISA slots linger on most motherboards, they are on the way out, replaced by the newer 32-bit slots
