A program is a fictional character that is featured in the American science fiction franchise of Tron produced by Disney. They are electronic beings created by users that inhabit the digital world and have unique traits of looking exactly like their user counterparts in the real world. However, despite their human appearances, they are completely different beings than users. Programs live on pure energy and have circuitry all over their armor or robes, which glow in different colors that vary from program to program.
