I have some doubts in distinguishing these two operations, they are similar but I think not the same, although both have to be with input and output of some "thing".

No difference. I / O is Input / Output. I / O is Input / Output. That is, it's just a translation issue.
IO operations are all that the operating system deals with devices other than the processor or memory.
