Document Summary

Binary values the way in which computer hardware represents and manages information. At the lowest level, computers store all information using just the digits 0 and 1. Number: a unit of an abstract mathematical system subject to the laws of arithmetic. A number is a representation of a value, and certain arithmetic operations can be consistently applied to such values. Numbers can be classified into all sorts of categories Natural number: the number 0 and any number obtained by repeatedly adding 1 to it. Negative number: a value less than 0, with a sign opposite to its positive counterpart. Integer: a natural number, a negative of a natural number, or zero. Rational number: an integer or the quotient of two integers (division by 0 excluded). Any value that can be expressed as a fraction. Base: the foundational value of a number system, which dictates the number of digits and the values of digit positions.
