Apologies for asking here, I have a hard time with finding the right google results or understanding overly complex explanations sometimes..
I did a little reading and my little understanding is that I/O is to do with input/output either between hardware in a PC or between the PC and outside sources, but would like a few dumbed down specifics so that I can understand the graphs and system information in Process Hacker. I've only a few simple questions I think, so I hope not a difficult ask.
Firstly: What kinds of processes/actions/jobs cause I/O R/W/O rate? I can see a connection between I/O rate and disc rate even though they don't match 1:1, so I wonder if I/O rates are a total of all read/writes detected by the system including storage drives and network connections? What else might count toward I/O Rate?
Secondly: I see there is read, write, and 'other' for some stats in System Information, what counts as 'other'?
Thirdly: I also see that there is a stat called 'delta'. I've seen Delta listed in various places even outside of Process Hacker, so does 'delta' refer to?
Hope to hear back soon, thanks for reading and for any answers provided.
