Hello. I have a general computer question that may or may not be difficult to answer. My basic goal is that I would like to be able to visualize in my

mind how the different components of a computer all interact with each other. I would like to be able to visualize the process from the input (as with a

mouse), through the processing (which would include cpu, ram, hard drive, among others), and finally the output (as to the screen or a printer). Would

someone be willing to explain this to me or direct me to a resource where I could see a diagram or explanation of this? The reason I would like to be

able to do this is because I feel it would allow me to use resources more efficiently when writing programs, be able to better diagnose any hardware or

software problems that might arise, and allow me to be able to better identify bottlenecks. Thank you.

You are asking about the operating system architecture. OS interacts with the hardware through OS kernel which sends messages to all applications. An application can react to that message. Sounds easy but its not.

As a computer science major, I've had to take several classes that deal with what you're talking about. One of the most interesting classes that I had to take was Operating Systems. In the Operating Systems class, we learned about interaction with the Kernel as well as how scheduling algorithms work.

What I'm trying to say is, if you'd like to learn more about how these things work, grab yourself an operating systems text book; or simply do some research on how the Linux kernel works.

Once you do a bit or research, it may be good to try some loadable kernel modules, and some system programming.
