Computer programs are sets of instructions. Each instruction is translated into machine code - simple binary codes that activate the CPU. Programmers write computer code and this is converted by a translator into binary instructions that the processor can execute. All software , music, documents, and any other information that is processed by a computer, is also stored using binary. Everything on a computer is represented as streams of binary numbers.
Audio, images and characters all look like binary numbers in machine code. Mar 28, Joel Evans Apr 26, Apr 26, I got the email for the approval but even this time it did not tell me you replied. Apr 27, OK thank you and do you want me to link the brainpop I mentioned. We'd love to see what you found! Thanks for sharing, Joel! Robert Mar 15, Mar 16, Yes indeed!
Did you enjoy this Wonder? Mar 15, Anonymous Mar 14, I get it! Mar 14, Sep 13, We are dying to know what you said! Apr 11, Very slowly using combinations of 0's and 1's.
As cool as the other side of the pillow, Noah! Manoj Mar 13, Re Mar 13, Is it possible to speak in binary code? Lynn Mar 9, Hello again! I'm part of my school's Math Team, and I've been surprised with adding in binary code on one of the competitions. I found out that adding binary codes is actually different from adding the numbers stated in this article, so is there two binary codes or just one?
Maybe there is a computer binary code and a math binary code, or maybe it's just all in one and I don't really understand binary code after all. Mar 13, Cat Mar 9, Kool Kat Mar 17, Mar 17, How do you feel about binary code?
So glad you liked it, Cat! Mariah Mar 9, Mar 10, So glad you think so, Mariah! Tyler Mar 9, Congrats, Tyler. You really deserve it!

Be the first to know! If you count on your fingers with binary you can count to 31 with one hand! With two hands, using binary, you can count up to ! Computers use binary because they can only read and store an on or off charge. So, using 0 as "off" and 1 as "on," we can use numbers in electrical wiring. Think of it as this — if you had one color for every math symbol 0 to 9 , you'd have ten colors. That's a lot of colors to memorize, but you have done it anyway. If you were limited to only black and white, you'd only have two colors.
It would be so much easier to memorize, but you would need to make a new way of writing down numbers. Binary is just that — a new way to record and use numbers which is true.
In school, you were taught that we have a ones, tens, hundreds columns and so on. Each column is worth ten times more than the next one. If you haven't seen it before, this columns idea looks like this:. This method lets us read binary numbers, but how do we write them? One way is to write a list of all the numbers starting from one and working upwards.
Follow along with this table to see how that works. You'll notice that the values 1, 2, 4, 8, 16 only need one one bit and some zero bits, because there's a column with that value and we just have to set the bit in that column to one. We can erase this work here. And then for the number, let's just flip the bits. Zero becomes one, one becomes zero, zero becomes one, and one becomes zero. What do you think this equals and decimal? I'll give you a second to think about it.
Now let's figure it out together. There's a one in the ones place. So this so far equals one times one, that's one.
There's a zero in the twos place. So we add zero times two, that's zero. There's a one in the fours place. So we add one times four, that's four. So so far, we've got four plus one, and then there's a zero in the final place, the eights place, that's zero times eight or zero. So we've got zero plus four plus zero plus one, which equals five in decimal. Let's try converting a bigger binary number to decimal. We know that this equals five. What happens if we add four more digits to the left of these four digits?
Let's start by figuring out what each place represents. One way of doing that is just to double the previous places. So this place here is 16, this place is 32, this place is 64, and this place is
