![]() For every 1 in a bit place n, add the value of 2^n to your total. ![]() So how do 8 bits turn into a value from 0–255? Let every bit place n represent 2^n, starting with index 0. Even today, most computers are built on multiples of 8 bytes to process data.Įach n place in the 8 binary digit sequence represents 2^n. Ultimately, 8 bit bytes became the standard. Since it was the smallest useful amount of bits, it became the core value for storing data in computers. These varied length sequences became known as bytes - in any system, one byte was used to encode one character on a computer. Originally, computers chose different lengths of bit sequences to encode data. ![]() But in a sequence, it can represent many more. Quick history lesson: A bit - binary digit - represents our most basic unit used to compute. As the name may have tipped you off, these are unsigned (meaning no negative numbers) 8 bit integers.Ĩ bit integers are extremely important in the history of computing. ![]() If you’ve ever handled files at all with Javascript, you’ve probably seen the Uint8Array typed array or ArrayBuffer object either one is frequently caught handling a large array of numbers, each ranging from 0 to 255.
