It has even more meanings in different systems. Typewriters had no CPU or memory at all and they were handling such "numbers" pretty well, because it's just text.

None of them can hold the entire, numerical value, but interpreted individually as ASCII characters (for example, the character ' 0' is represented by decimal value 48, binary value 00110000), they can be strung together into a format that makes sense for you, a human.Ī related concept in programming is typecasting, which is how a computer will interpret a particular stream of 0s and 1s. Each individual byte can hold a value of up to 255. To literally display the number "1000000000000" requires 13 bytes of memory. The printed string "1000000000000" is not represented by a 32-bit integer in memory. However, the value of this 32-bit integer and how it appears on your screen are two completely different things. You are correct that a 32-bit integer cannot hold a value greater than 2^32-1.
