I know that the cpu interacts with i/o devices through a bus. I was wondering what is physical hardware used to make the bus?

 

Resistors, transistors, maybe some diodes, copper wire.

 

Slots and edge connectors for various expansion card standards e.g. PCI etc.

Hello,

The links of the following page of the EDUCYPEDIA will give you some info on the different bus systems in computers:

bus is simply a word used to label a concept that is somewhat imaginary.
The real bus is simply a wire, junction or node in the circuit. It is implemented with conducting wire, usually made of copper.

In the development of microcontrollers, from the beginning of the 70s, the bus has been reference to denote the capacity in management of data and memory addressability. They usually have three types: data bus, address bus and control bus, which, as already stated, are physical connections of copper cables.
