Computer Networking Tutorial - 22 - How Binary Code Works



what's up guys it's Bucky and in this tutorial I'm going to be showing you guys how binary code works now in case you don't know what binary code is is pretty much all those zeros and ones that the computer understands what you can't and with these zeros and ones it could translate that to make any number in the world and I know you guys are asking how can you make any number using just zeros and ones well I promise you by the end of this tutorial you were to learn that now in case you ever heard someone talking about bits and bytes probably if you've ever been around a computer if they say my RAM has 512 megabytes in it or I have a 32-bit processor or like Nintendo 64 and stuff that 64 is based on bits and bytes in binary code so by the end of this tutorial you're going to understand all of that but before we understand bits and bytes we need to first understand how our number system works our number system is a base 10 number system that means we got 10 numbers to work with 0 through 9 unlike binary which is a base to computer system which means it only has two numbers ones and zeros and um let me show you guys a number real quick well this pretty much represents is that any number can root can be represented by combining any other number in our system so if we want to make the number 463 we need to use the for the 6 into 3 now the 3 represents the 1 spot the 6 represents the 10 spots in the 4 represents the hundreds spots and as you can see as I'm talking those are all 110 100 a thousand million those are all factors of 10 so that's pretty much how our number system works on base 10 but the computer number system it works a little bit different it only has two numbers and this this is just a little tidbit of information the word bit comes from binary digit C bull it bit and for example if you wanted a 4-bit system that means you're going to have four numbers one zero zero one or it could be 1 1 1 1 or 0 0 0 however many numbers you have that's how many bits are in your system now let's just get down to it and let me explain to you guys how binary code works now as you can see instead of 1 10 100 1000 we increment in factors by 2 and that is 1 2 4 8 and the next number you can just go along with by timesing the previous number by 2 in by using these numbers we can come up with any number from 0 to 128 now as you can see this is a basic 8-bit system but if you want to use a bigger range of number say you want to go to like 6 billion then you might use something like a 64-bit system but this is pretty much an 8-bit system and by the time I'm done showing you guys how this works you're going to be understand you're going to understand how a 64 256-bit system works so we're saying all right what if I want to get the number of 19 now if I had a 10 based system I'll just write 1 and 9 but we don't we have this 8-bit system so what the heck are we supposed to do what you have to do is look at all of your bits 128 64 32 16 8 4 2 1 and there's only one way that you can add these numbers to create the number 19 so you start with the biggest number and that's 128 if you can use 128 in 19.1 if you can't put 0 so can 128 go into 19 no it can't 0 can 64 nope still bigger 32 nope still bigger can 16 go into 19 yes it can go in once now what you have to add to 16 to get 19 do you add 8 nope to add 4 nope that will give you 20 do you add 2 yeah but that will give you 18 do you add 1 yep that gives you 19 right there so an 8-bit system the binary code for 1900 0 1 0 0 1 1 and the computer understands this and it's just job to take all this code and interpret it into the number 19 so let's do another 1 or 2 say you um say you want the number uh 64 let me just write there write it right there can 128 go into 64 nope can 64 go into 64 yep and there is no need since we already have it we just fill in all the rest for zeros right here right there so the binary code in an 8-bit system and remember 8-bit system means there 8 numbers 0 1 0 0 0 0 0 0 and that means 64 and as you can see by using this we can get any number from 0 to 128 and if you're saying alright how do I get 0 if there's no 0 that's easy just plus 0 for everything 0 0 0 0 0 0 0 0 and no matter how many bit systems you're running all zeros mean is 0 and of course the maximum that you can have actually I lied this is a 255 so this has a range from 0 to 255 and if you're wondering alright how do I get the number 255 128 plus 64 plus 32 plus 16 plus 8 plus 4 plus 2 plus 1 equals 255 and if you don't believe me then you can check it and if you want 254 just change this one to 0 128 plus 64 plus 32 plus 16 plus 8 plus 4 plus 2 equals 254 so those are the basics on how binary code works and how you can use ones and zeros to combine these and I use this to get any number you ever dream them your only limitations is how many bits are on your system and that's what scientists in whatever the engineers are trying to develop to get the biggest bass bit system so we can transfer more data and have a bigger range of numbers so the that is your simple tutorial on how binary works so now that you understand how you can use ones and zeros to get any number on the computer I hope you learn something thank you guys for watching make sure if you have any questions to check out my website – New Boston comm and I'll answer any questions you have there
