Who, what, or how is memory-mapped I/O and memory maps set up in computer systems for use? I will try and be as clear as possible, and I hope someone here has the knowledge to really understand what I'm asking thoroughly, and have some answer that's good enough to make sense for me and future readers. Here I go...

After that, I assembled it once again. Also, I used the air compressor to clean the power source. After it was all assembled, I tried turning the PC on....and it didn't. Now, this was an old PC, but it was functioning before I started. …
