Data Storage and Binary Numbers

Data is stored in binary. Binary is a base-2 number system that only uses the numbers 0 and 1. Every character we store from our keyboard is stored as a byte of data. One byte equals eight bits. One bit equals either a 0 or a 1. For instance, A = 0000/010. Bits are stored as electrical charges while all data is as a sequence of electrical charges. 3.3 volts and above equals a 1.The number 1 means on, positive, or true. Anything less than 3.3 volts equals a 0. The number 0 means off, negative, or false. All characters (numbers, symbols and letters) are processed and manipulated using the binary number system.
