Central Processing Units do not have "external units". There are many things outside (external to) the CPU, but nothing named an "external unit".
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.).
Hard wares are those parts of the computer which can be seen ands touched unlike software. They include all types of computer external parts and CPU devices.
