Difference between "Hello, World!" program and Computer program

"Hello, World!" program vs. Computer program

A "Hello, World!" program is generally a simple computer program which outputs (or displays) to the screen (often the console) a message similar to "Hello, World!" while ignoring any user input. A computer program is a sequence or set of instructions in a programming language for a computer to execute.
