Execute
EK-sih-kyoot
/ˈɛksɪkjuːt/
To carry out or put into effect (a plan, order, or course of action). (In computing) To run a computer program or instruction.
In computing, 'execute' specifically means to perform the actions specified by a program or a command. It's the final step after writing and compiling (if applicable) the code.
The story behind the word. The word 'execute' comes from the Latin 'exsequi,' meaning 'to follow out, pursue, perform, accomplish.' It's a combination of 'ex-' (out) and 'sequi' (to follow). Historically, it meant to carry out a task or fulfill a command. In the realm of computing, this meaning was directly applied to the process of a computer following the instructions of a program, carrying them out step-by-step.
