The Tron system is Kevin Flynn's digital universe, an artificial digital environment created to form a "Newtonian playground" where all thought and experimentation can proceed at a vastly accelerated rate over what people can achieve in the real world. Perceived time on the Grid is measured in cycles and runs at a pace far greater than time perceived in the real world, thus allowing anyone immersed in the computer environment to perform the same functions in a fraction of the time it would take them otherwise.
