example
For example, it is like guiding you to make a menu, or directing a traffic policeman (or a traffic sign) to drive all the way to the destination. Without these special instructions, the expected task will not be carried out.
So is the computer. When you want a computer to do something for you, the computer itself can't actively work for us, so we have to give it instructions, and it can't and can't understand the description of things in human natural language at all, so we have to tell the computer what to do and how to do it with programs. Even the simplest tasks need instructions, such as how to get keystrokes, how to put a letter on the screen, how to save files on disk, and so on.
