asynchronous bus A bus that interconnects devices of a computer system where information transfers between devices are self-timed rather than controlled by a synchronizing clock signal.
In computers, the bus is the subsystem that transfers data between internal parts of the computer, or from internal parts of the computer to external parts, or between two computers. External bus can be parallel (ATA (and all of its derivations), IEEE-488, SCSI) or serial (USB, FireWire, etc.).
