Computer  Work

Transcript

00:00Mom said we're getting a new computer!

00:02Yay!

00:04But I really don't know what a computer is.

00:07I can help you there, Tover.

00:09Oh, hi, Uka.

00:11This is my friend, Uka.

00:14Uka, you work with computers, right?

00:18Can you tell us how computers work?

00:21What is a computer, anyway?

00:24Well, there are all kinds of computers.

00:26Some of them are very large, and some are very small.

00:30You're probably talking about a personal computer, the kind you have at home.

00:34This could be a desktop computer, or a laptop, or a tablet.

00:38Even your smartphone is a computer.

00:40Oh, well, why do we need all these computers?

00:45Computers? Compute!

00:47Do you know what that means?

00:49Like adding and subtracting?

00:52Right. Computers see the world as if it's made of numbers.

00:56Actually, just two kinds of numbers, ones and zeros.

01:00By making everything very simple, adding and subtracting ones and zeros,

01:04computers solve problems way faster than people can.

01:07Oh, well, my mom says she uses a computer to do work,

01:14but she says I'll be able to play games with it, too.

01:18It's true.

01:19You can use a computer to do work, but you can also use a computer to have fun.

01:23Wow! Really?

01:25You can use it to do your math homework, or draw a picture, or go on the internet.

01:30We send emails using computers.

01:32I'm talking to you right now on a computer using video chat.

01:35Gosh! Computers must be very, very smart!

01:39They're only as smart as their software.

01:41That's the instructions that tell the computer what to do.

01:44Which part is the software?

01:47Can you point to it?

01:49No, I can't point to the software.

01:51All the parts you see, that's the hardware.

01:53Hardware and software?

01:56That's a good joke!

01:59You're funny, Ooka!

02:02I'm actually being completely serious.

02:05Computers work by combining hardware and software.

02:08Hardware is anything physical.

02:10Anything you can see and touch.

02:12Like the monitor, the keyboard, and all the parts inside the computer.

02:16All those wires and circuits.

02:18That's where the real work gets done.

02:20On this circuit board, you'll find a computer's CPU,

02:23the central processing unit.

02:25That's like the computer's brain.

02:27Oh! So what do you mean by software?

02:30Software is the set of instructions that tell the computer what to do.

02:34That's where we come in.

02:36We do?

02:37Yes. Your computer doesn't have any idea what it's doing.

02:41In fact, it won't do anything at all, ever, unless you tell it to.

02:46Wow! That's a lot of power!

02:49Yes. You need to be very careful about what kinds of instructions you give your computer.

02:54Or, it won't work properly.

02:57Oh! Well, how hard can it be?

02:59Would you like to try to write very careful step-by-step instructions?

03:03Like how a computer needs them?

03:04Sure, sure, sure, sure. I got it, I got it.

03:07Then let's make a peanut butter sandwich.

03:09Oh! I know how to do that.

03:11I make myself peanut butter sandwiches as a snack, sometimes after school.

03:17Good! Then this should be very easy for you, right?

03:20Right!

03:21Pretend your computer has hands.

03:25How would you tell it to make a peanut butter sandwich?

03:27Well, you take some bread and some peanut butter, and you put the peanut butter on the bread.

03:35Like this?

03:37No! That's silly!

03:40Well, the computer doesn't know that.

03:42You have to tell it everything, step-by-step.

03:46Try again.

03:47Okay, okay.

03:49You take some bread.

03:51Wait.

03:51You open the bread and take two slices out.

03:55Now, you take your peanut butter and put it on the bread.

04:00Like this?

04:01Oh my gosh!

04:03Now, let's start again.

04:07You open the bread.

04:08Take out two slices.

04:10Put them on a plate.

04:13Now, open the jar of peanut butter.

04:16Stick a knife in.

04:18And use it to put the peanut butter on the bread.

04:22Stick the two pieces of bread together.

04:36Mmm.

04:36Looks like a pretty crunchy sandwich there.

04:39Oh my gosh!

04:43One more time.

04:46Open the bread.

04:49Take out two slices.

04:50Put them on a plate.

04:53Open the jar of peanut butter.

04:55Stick in a knife.

04:57Use the knife to spread peanut butter on the bread slices.

05:03Put away the knife.

05:07Close the two pieces of bread together.

05:10Okay, that looks like a pretty good sandwich.

05:19Now, do you see what I mean about having to be very careful with your instructions?

05:23Yes!

05:25That's what software is.

05:27The step-by-step instructions you give your computer.

05:30One set of instructions is called a program.

05:33You just wrote a peanut butter sandwich program.

05:36I think I could get the hang of this.

05:38One more thing, Topher.

05:39We've been speaking English to your computer.

05:42But computers actually speak different languages.

05:45Like French?

05:47Non, mon petit chou.

05:49Computers speak computer languages.

05:51For example, Python, Java, C.

05:55Those are all names of computer languages.

05:57Computer programmers, like me, learn these languages so we can talk to computers.

06:02Here's an example of some computer code in Python.

06:05Oh, I know some of those words.

06:10Can anyone become a computer programmer?

06:13Sure, Topher.

06:14Everyone can learn how to code.

06:16It's just like solving a puzzle.

06:18I love puzzles!

06:19Me too.

06:21Hey kids, would you like to become a programmer?

06:24If you have a computer, you can play around and learn what happens when you give it different instructions.

06:29Tell us in the comments about how you use computers.

06:33I bet you're using one right now.

06:37Wow.

06:37Oh, wow.

06:38That was fun.

06:39We learned about computers.

06:40That was great.

06:40Oh, look.

06:41Wow, there's some more puppet science videos here.

06:44Hey kids, want to see some more puppet science?

06:48Well, there's some more videos for you to pick.

06:51Like that one.

06:52Oh.

06:53Or this one.

06:54Oh.

06:55Come on, pick.

06:56Come on, pick.

06:57Come on, pick.

06:59Come on, pick.

07:00Come on, pick.

07:01Come on, pick.

07:02Come on, pick.

07:03Come on, pick.

07:04Come on, pick.

07:05Come on, pick.

07:06Come on, pick.

07:07Come on, pick.
