C

C is a programming language designed by Dennis Ritchie at Bell Labs. C is very widely used, straightforward, and can be compiled to a number of platforms and operating systems. C is an imperative language, with a small number of keywords and a large number of mathematical operators. C is also a very low level programming language, which means it can communicate directly with hardware.

A unidirectional network (also referred to as a unidirectional security gateway or data diode ) is a network appliance or device allowing data to travel only in one direction. It is used in guaranteeing information security. They are most commonly found in high security environments such as defense, where they serve as connections between two or more networks of differing security classification – also known as a "cross domain solution." This technology is also found at the industrial control level for such facilit ies as nuclear power plants, electric power generation/distribution, oil and gas production, water/wastewater, airplanes (between flight control units and in - flight entertainment systems), and manufacturing.
