Definition - What does Tautology mean?
Techopedia explains Tautology
The use of tautology and tautology checking is an example of the intersection between computer programming and higher mathematics. Because computer programming is built on a rigid syntax in order to communicate with the hard logic of a machine's language, programmers and engineers often discuss concepts in terms of higher mathematical principles and equations. Using conventions like tautology shows how the algorithms of today's technologies are reminiscent of the complex equations that mathematicians have always done cognitively in the human brain.
