Well technically a bus is a group of wires shared amongst several devices. Each device has to wait its turn to talk/listen.
PCI, AGP, ISA, IDE are busses.
PCI express, USB, SATA are not busses but rather point-to-point protocols.
- fulafel 6y agoThe usage of the term has changed a bit. From WP: "Early computer buses were parallel electrical wires with multiple hardware connections, but the term is now used for any physical arrangement that provides the same logical function as a parallel electrical bus. Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of USB. " (The B in USB stands for Bus)
