   What is an I/O channel?

   • Glossary » I » An I/O channel, also known as an input channel, is a data communication channel between the input/output bus and memory to a computer peripheral or CPU. It executes I/O instructions and controls I/O operations based on the CPUs instructions.

   What is a channel I/O instruction?

   • The CPU of a system that uses channel I/O typically has only one machine instruction in its repertoire for input and output; this instruction is used to pass input/output commands to the specialized I/O hardware in the form of channel programs.

   Why is Channel i/o important?

   • Channel I/O provides considerable economies in input/output. For example, on IBM's Linux on IBM Z, the formatting of an entire track of a DASD requires only one channel program (and thus only one I/O instruction), but multiple channel command words (one per block).
