CATIA (computer aided three-dimensional interactive application) is a multi-platform computer-aided design (CAD)/computer-aided manufacturing (CAM)/computer-aided engineering (CAE) software suite developed by Dassault Systèmes. Written in the C++ programming language CATIA delivers the unique ability not only to model any product, but to do so in the context of its real-life behavior: design in the age of experience.

Community Access Television (CATV) commonly known as Cable TV, is one of the most common methods of transmitted television signals to a consumer's home, using radio frequency signals transmitted through coaxial cable. More recently, CATV can also be transmitted using optical fiber, which utilizes pulses of light to transmit a signal.
