Throughout history almost every civilization has used a decimal number system with ten digits 0 through 9 all of the numbers we can possibly think of use some combination of those 10 digits computers however operate very differently instead they use a number system that has just two digits 1 & 0 this system is called binary and your .

Computer uses it all the time computers need information in order to do what they do this digital information or data is made up of something called bits bit is short for binary digit meaning each bit is really just a single number either a 1 or a 0 these bits can be combined to create larger units like bytes megabytes and so on that we use to .

Measure our files the larger a file is the more bits it has so something like a high resolution video is actually made up of millions and millions and millions of ones and zeros so how exactly do these ones and zeros come together and allow a computer to function let's think of binary as a light switch imagine that a one represents the light switch being .

On and zero represents it being off with binary the light is either on or off with no other possible States so these bits are strung together as different combinations of ones and zeros and they form a kind of code your computer then rapidly processes this code and translates it into data telling it what to do you might be wondering why do .

Computers use binary instead of the decimal system that we use for counting things in the real world well as previously mentioned binary has two states off and on if computers were to use decimal there would be 10 states instead our computers would have to work a lot harder to process all of these binary is easier for them to process and .

Also takes up less space just like atoms make up everything around us in the real world everything in the digital world including video text pictures and more can be broken down into binary and even though we can't see them it's all a bunch of ones and zeros GCF global creating opportunities for a better life .
