What is Programming?

Programming is the process of creating computer programs. But this definition raises another question: What exactly is a computer program?

A computer program is a combination of computer instructions and data that enables computer hardware to perform calculations or control functions.

Understanding Through Analogy

Let's break this down in a more accessible way:

Imagine a computer program as a robot. You have a home robot, and you give it specific commands to perform tasks.

For example, suppose you want your robot to open the door every time you come home. At first glance, this seems like a simple task, but the process of a robot opening a door can actually be broken down into several stages:

1. Stage One - Your robot must stand near the door and watch for your approach
2. Stage Two - As you approach the door, the robot must extend its arm and grasp the door handle
3. Stage Three - Once the robot has grasped the handle, it must turn it down and pull the door toward itself to open it

Now your robot successfully completes the task - it opens the door for you. As you can see, even such a simple function as opening a door can be divided into several small steps that the robot doesn't know until you provide it with the appropriate commands beforehand.

In essence, this phenomenon can be compared to programming - the process of providing a set of commands for your program to execute.

Key Concepts

• Instructions: Step-by-step commands that tell the computer what to do
• Data: Information that the program works with
• Execution: The process of running these instructions
• Logic: The rules and conditions that guide program behavior
