Abstract.The concept of function is an example of a topic which has connections in almost all areas of computer science, especially in digital logics. In designing digital logics, there may be situations in which the designer may need the system to be able to ``undo" certain processes. If that is a requirement, what the designer does, in simple mathematical terms, is to restrict the domain of operation in order to allow the process to be a function which is one-to-one. The purpose of this short note is to discuss some simple logical operations and terms associated with computer science in the context of functions. This will provide beginning students of computer science a thorough understanding and some examples of the concept of functions.
