Document Summary
A bit is a single binary digit, one or zero. A word is the amount of memory read at one time by the cpu. Some new ones use 64 bit architectures which means they have 8 byte words. Pointers are one word long, so the word size determines the maximum amount of memory your cpu can reference. Each bit represents a power of two, with. With n bits, we can store any number from zero to. Each bit represents the same power of two, but the highest (leftmost) bit is negative: With n bits, we can store any number from complement integer, flip all the bits and then add one. to. In hexadecimal notation, each digit represents the coefficient of a power of 16. We can have a coefficient as high as 15, so we use 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f as our digits (capital letters are also fine).
