What Does Bus Mean?
A bus is a subsystem that is used to connect computer components and transfer data between them. For example, an internal bus connects computer internals to the motherboard. A “bus topology” or design can also be used in other ways to describe digital connections.
Techopedia Explains Bus
A bus was originally an electrical parallel structure with conductors connected with identical or similar CPU pins, such as a 32-bit bus with 32 wires and 32 pins. The earliest buses, often termed electrical power buses or bus bars, were wire collections that connected peripheral devices and memory, with one bus designated for peripheral devices and another bus for memory. Each bus included separate instructions and distinct protocols and timing.
