I have been studying buses used in communication systems. From what I read at Wikipedia,
"In computer architecture, a bus (from the Latin omnibus, meaning "for all") is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocol."
Does that mean both a wire and a bus is the same thing? What feature makes the bus totally different from a normal wire in the first place?
