MORE BASICS:

MINOR CORRECTIONS:
In the graphics, “programme” should be “program”.
I say “Mac instead of PC”; that should be “a phone instead of a PC”.
And most importantly, I say “every sixth cycle”: that should be “every ninth”.
Fortunately, none of these materially affect the content of the video!

  1. I got lecture for 1 and 1/2 hr for this topic (Computer Organization and Architecture) Simple As Possible -1 , I only understand a little from it. This video helps alot. This video should be shown to people who is curently learning COA for easier understanding. Great video!

  2. I have been following you for years, watching your videos about everything from cool stories about geography, games… Last year I started studying computer science, and tomorrow I have a test on computer structure. I had no clue on the fetch decode execute cycle, and was desperately looking for something on youtube (as one does). I saw your face and was inmediately relieved, as your narrating skills would make me get it instantly. You have saved a fellow computer scientist my friend.
