Modular arithmetic. Time-keeping on a clock gives an example of modular arithmetic. Modular arithmetic, sometimes also called clock arithmetic, is a way of doing arithmetic with integers. Much like hours on a clock, which repeat every twelve hours, once the numbers reach a certain value, called the modulus, they go back to zero. People talked about modular arithmetic in many ancient cultures.
It is not to be confused with code refactoring. Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.urthermore, the term package has other uses in software. A component is a similar concept, but typically refers to a higher level; a component is a piece of a whole system, while a module is a piece of an individual program.
