I was studying the I/O process of a PC...and I think I understood it..but not very much so I will type what I understood giving an example..and I hope that I got it right e.g. typing with a keyboardFirst: The Input, and that is done simply by the keyboard..Second: The information gets to the CPU in binary, but the logic unit doesn't understand it so the Control Unit gets the Instructions saved in the RAM by the CU it self..then the instructions is sent to the Logic Unit through the CU Finally:The Logic Unit understands it that time and do some operations that produces some Outputs.The outputs are saved in the RAM, and viewed on the screenSo, please tell me if that's right or if I missed the whole thing..Thank you very much in advance.
How does the CPU receive, process and output information?
