Can anyone tell me what a bus actually is? I know it is the link between the processor and memory and disk, but what actually is it? i.e. a wire, a piece of hardware, etc.
Cheers.

Well, there are a lot of devices on the bus.  The bus protocol says which devices can "talk" to each other and when.  A code of conduct of sorts...
