ISA
Definition: Industry Standard Architecture: the architectural standard for the IBM XT (8-bit) and the IBM AT (16-bit) bus designs. In ISA systems, an adapter added by plugging the card into one of the 16-bit expansion slots enables expansion devices like network cards, video adapters and modems to send data to and receive data from the PC's CPU and memory 16 bits at a time.
