    Reason for my vote of one: (and I suspect for the others) Wrong. It is so completely wrong, that there is almost nothing in there that is actually correct. I don't often give down votes, but I'm making an exception in this case! Sorry, but you really need to go back to the beginning and start learning this stuff again.

    I read Jeffrey Richter's book on CLR but I must have totally misunderstood what I was reading. Hopefully someone will explain the difference in this topic. At the moment I'm aware I've got it wrong. I just don't know why.

      I hope I don't bother anyone with my simple and newbie-look-a-like questions :) The title itself is clearly indicating what I want for the answer. So thanks for your help

      This uesd to be a lot easier question to answer - the stack was a small bit of RAM pointed to by the CPU Stack Pointer (SP) register, which made it fast and easy to access. Every CALL instruction pushed the current values in all CPU registers onto the stack, then popped them back when the CALLed routine was finished to resume execution. The Heap was a block reserved in RAM by an application to hold and access run-time data. Now it's a bit more complex, but this[^] discussion puts it in perspective.

          I understand what you are trying to say but I didn't have another choice and I thought this is the right place to ask that problem. I already excused for my question you consider non-advanced and unprofessional :) . I hope you realize why. ;)

            You do realise that OG wasn't addressing you don't you? What he was saying is that the answer you were given was wrong - not that you were stupid for asking the question. It's actually a pretty fair question, as the concepts are misunderstood, which you can see from the answers.

                No, no, you misunderstood - that was not directed at you or your question (which is a good, sensible question). That is why it was a reply to RobCroll and not to you, and why his answer is light grey, and yours is still blue. His answer to your question was wrong in just about every respect, and what he said you should ignore - look at Dave Kreskowiak's answer which is much, much better. That is why I (and I suspect others) voted him down - the advice was bad. If you look at the bottom left corner of a message you will see a "rate this message" facility. Have a look at his answer: 1.71/5 (7 votes) indicating he has had seven ratings, and that they have generally been unhappy. A vote of one is a "this is bad", a vote of 5 is a "this is good". If your message has no votes, it is blue, if it is down voted, it goes grey. If it is upvoted it goes green.
