On the myth machines, pointers are bits long, meaning that a program can address up to bytes of memory, because each byte is individually addressable. This is a lot of memory! It is 16 exabytes, or x bytes. Older, bit machines . Bits can be expressed in hexadecimal with no loss of generality Easier for humans to read! Because bytes can be expressed using two digits in hex (one digit for the first 4 bits, one for the next 4 bits) it’s a very widely used system for binary coding. Trying to look over an undifferentiated mass of 0s and 1s is difficult, so we organize them into groups of eight. A set of 8 bits is referred to as byte. While bits and bytes are represented by the state of electronic switches in computer memory, they . In June , Werner Buchholz coined the word byte to refer to a group of bits used to encode a single character of text. Let’s address character encod-ing, starting with ASCII (American Stan-dard Code for Information Interchange). The Untold Story of the Computer Revolution: Bits, Bytes, Bauds, and Brains: Author: George Harry Stine: Publisher: Arbor House, Original from: the University of Michigan: Digitized. Bits and Bytes Prerequisite: Know Binary and Hex. View previous document, “Binary, Decimal, and Hex” for help. Bits A bit (short for “BInary digiT”) is the smallest unit of data in a computer. The bit can be represented by a 1 or 0. A single bit can be used to represent on/off or yes/no but a string of bits can represent complex data.
