This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
1 System Bus: A parallel bus that simultaneously transfers data in 8-, 16-, or 32-bit channels and is the primary pathway between the CPU and memory. 2  Internal Bus: Connects a local device, like internal CPU memory.  External Bus: Connects peripheral devices to the motherboard, such as scanners or disk drives.
