Bhoot Came Inside This Women and See What Happened

Computer Science experience with computer science, contrary to what you might think. So today we thought we would chip away at that lack of familiarity, but also give you a sense of, for those of you with more comfort, which directions you can go this semester.

Bhoot Came Inside This Women and See What Happened

So let’s start with this. I really have no idea what’s inside of computer, even though, like you, I use it every day. But it’s some kind of box, and there’s not many inputs into it. Minimally, there’s, what? Probably a power cord. And indeed with this one ingredient, electricity, we seem to be capable of doing quite a bit these days.

But at the end of the day, we have to represent the things that we care about. We have to represent information in some form. And you’re probably at least vaguely familiar with the idea by binary or bits somehow or other, computers reduced to zeros and ones.

But can we embrace that and at least put a bit of light to that? > Bhoot Came Inside This Women and See What Happened > So I have these little desk lamps here. I have an electrical outlet here.

And I’m going to propose that inside of my computer Introduction to Computer Science is at least one of these things, something capable of being switched on or off. In this case, it’s indeed a desk lamp, but at the lower level, it’s something called a transistor. But in our world, it’s a desk lamp, so I’m going to go ahead and plug this into my electricity here.

So whereas that’s the ones place, thesis going to be the twos place, this is going to be the fours place. And because I am only using the simplest of mechanisms to turn things on and off– electricity is flowing or electricity is not flowing– I don’t quite have the same expressive range as 0 through nine.

We’re going to keep it super simple in this world of computers. I only have 0 or 1– off or on, false or true.And so what I’m representing right now is 1, 1, 1, because each of these lights is illuminated.

Well, that gives me one 4 plus one 2, so that’s 6, plus one 1, and that’s 7. And ergo does this sequence of three bits represent the number 7. So all this time, inside of your computer, have been any number of transistors, any number of bits.

But at the end of the day, we can represent information as simply as that. Now unfortunately, we’ve only counted up to 7 in CS50 thus far, but hopefully we can do a bit better than that. And indeed we can. Suppose that we as humans just arbitrarily decided that we are going to associate numbers like 1 and Bhoot Came Inside This Women and See What Happened, with specific letters of the alphabet.

And for historical reasons, I’m going to start somewhat arbitrarily, but I’m going to say, humans, we are going to decide as a standard, globally, that 65 represents the number the letter A.

And let’s suppose, if we really put some thought into it, we could come up with numbers for exclamation points and lowercase letters, and indeed, other people have done that for us. So now we had bits with which we can represent numbers, numbers with which we can represent letters, and with letters can we now start composing emails and printing characters on the screen.
