I/O

Refers to an operations, program, or device whose purpose is to enter data into or to extract data from a computer.

IRQ

Interrupt Request Channel. The IRQ of a host adapter can be changed to several different settings by changing jumpers and/or switch settings on the adapter board.

ISA

Industry Standard Architecture expansion bus. A type of computer bus used in most PC’s. ISA 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. Expansion devices are plugged into sockets in the PC’s mother- board. ISA is sometimes called the AT Bus, because it was originally introduced with the IBM PC-AT in 1983. (PC/104 follows this standard.)
