Execute and execution are terms that describe the process of running a computer software program, script, or command. For example, each time you open your Internet browser, you are executing the program. In Windows to execute a program, double-click the executable file or double-click the shortcut icon pointing to the executable file. If you have a hard time double-clicking an icon, you can click the icon once to highlight it and then press Enter on the keyboard.
What happens when a file is executed?
When executed, a command, program, or script runs a series of instructions that tell the computer how to operate. What the computer does depends on these instructions. For example, one program may tell the computer to draw a circle, and a different program may tell the computer to draw a circle.
