From my last post "expansion bus" and "peripheral bus", "expansion bus" or "peripheral bus" are said to be the same concept. My questions here are not the same as those before. Please do read both of them, before you judge.
From the Wikipedia article "Expansion bus", expansion bus is defined as:
An expansion bus is made up of electronic pathways which move information between the internal hardware of a computer system (including the CPU and RAM) and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer.
As far as I know peripheral devices can be internal or external to the computer case. So I wonder if here peripheral devices mean external peripherals only?
- What is the opposite concept of "expansion bus" or "peripheral bus"?
