Computers use the binary system. 0 -off and 1-on. These are the Binary numbers and these are what can make the computer do more. Otherwise nothing would work out evrything has to be done in Binary. This system has a lot more to it. If u use 6 digits of 0's and 1's it has 63 outcomes. A 0 or a 1 is called bit. 8 bits are called bytes. 1000 bytes are called kilobytes, 1000 kilobytes are called megabytes, 1000 megabytes are called gigabyte and lastly 1000 gigabytes are called 1000 terabytes.

It is important to round bytes to a thousand but actually its 1024 bytes to make a kilobyte and so on and so forth. This is because there is no exact 1000 in the place value of the binary numbers. Fingers are what we call Digits
