Newbie- Interaction Between CPU and Devices?

Newbie- Interaction Between CPU and Devices?

Newbie- Interaction Between CPU and Devices?

Hello- I'm entirely new to assembly and such, and I have several questions regarding the Interaction Between CPU and Devices.

How does the CPU communicate with various devices? Hows does it see if a device exists? What organization or standard, de facto or otherwise, determines how the CPU interacts with these devices?

I just look at all the computers these days with variable numbers of slots and capabilities- new computers with new features using the same old processors- where do I find out how to utilize these features?

I can't find it in the Intel Documentation, where do I look?

RE: Newbie- Interaction Between CPU and Devices?

I take it you are referring to Windoze & the PC?
