WebAn I/O module having this kind of architecture is known as an I/O processor (IOP). An IOP can perform several independent data transfers between main memory and one or more I/O devices without recourse to the CPU. Usually, an IOP is connected to the devices it controls, by a separate bus system called the I/O bus or I/O interface. Web19 jan. 2024 · There are two main types of buses: system bus and I/O bus.
