USA Bus Lines

How many devices can use a single computer bus at the same time-1,2,3, or Divide the number of bus lines by 8?

1. It could depend on the architecture of the bus, but most likely it would be logically limited by the number of unique address lines available on the bus. So if there is 1 address line then there could be 2^1=2 devices, 2 address lines = 2^2=4 devices, 3 lines=2^3=8, etc. There could be practical limitations with the hardware design that might limit the number, also (e.g. you may have a hard time designing a bus that has 1000 devices on it since the length of the wiring may have too much resistance to propagate the signal). Also note that "buses" don;t have to use address lines- they could be addressed in a data header. Simple Ethernet on a hub is an example of this type of bus.
