What Is Coding And How Does It Work?

what is coding and how does it work.

Code is very important for computers. Almost every electronic device we use relies on code. Maybe the way each code works is quite confusing, but when we break it down it's actually simple. People who create code are called programmers, coders, or developers. They all work with computers to create websites, apps, and even games! This time we will learn about what is coding and how does it work?

What is Code?

Computers have their own language called Machine Code that tells them what to do. Maybe this code would not make sense to humans! Each number or letter tells the computer to change something in its memory. This can be a number or a word, or a small part of an image or video. On its own, the computer does not know how to do anything. It is the programmer's job to give them instructions.

We should learn Machine Code, but it will take a long time! Fortunately, many experts in the IT field have created several programming languages ​​so that it is easier for us to communicate with computers.

What is a Programming Language?

Now, this looks a little easier to understand! This image shows how to tell the computer to say Hello World. Instead of us using machine code, it uses the Python programming language and it is one of the most widely used programming languages.

Almost all programming languages ​​work the same way:

 1. We write code to tell us what to do: print (Hello World).

 2. The code is compiled, which turns it into machine code that the computer can understand.

 3. The computer executes the code and writes Hello World back to us.

There are hundreds of different programming languages ​​that can be confusing, but they all do the same thing. We type what we want to do, the compiler converts it into a language the computer understands, and then the computer does it, which is called executing code in programming speak.

What is Coding?

Coding is the process of using a programming language to make computers behave the way we want them to. Each line of code tells the computer to do something, and a document full of lines of code is called a script.

Each script is designed to do a job. This job might be to take a picture and resize it. Maybe play a certain sound or music. When we click like on someone's post on social media, the script makes it happen. Unlike other people, the computer will do what we tell it to.

This may sound great, but it can cause problems. If we tell the computer to start counting up, and don't tell it to stop, it will keep counting forever! Being a good programmer is all about knowing how to tell the computer to act.

What is a Program?

Scripts themselves can only do things if they are compiled and then executed. This is useful while we're still working on it, but when we're done, we want people who aren't programmers to be able to use our script. What we need is to turn our script into a program.

When we are satisfied with our script, we can compile it into a program. As we already know, compilation converts code from our programming language into machine code that can be understood by computers. Then the machine code is stored in a program that anyone can download and use. Every kind of app, game or website is a program.

Is Coding Difficult?

Coding can be very simple, and anyone can learn the basics. A good analogy is to think of coding like a book in a library. Some books use simple language, and the stories are easy to understand. Others use very complex words and have stories that seem implausible. Whether it's simple or hard to read, everything is a book.

The more books we read, the better we get at them. Complicated language or confusing stories get easier to understand until one day we can read things we never even dreamed of in the past!

Learning to code is the same. The first time we try the code, we will find it difficult, but every time we do it we get better. If we find it difficult to learn a programming language, we can still learn the important ideas behind it using a visual coding language. We can even create a game without typing any code!

What Does the Code Look Like

The image above shows a script named Website Name. We have seen that a single line of code can make the computer print to the screen. Say we want the user to type in their name, and for the computer to greet them by name? Let's describe what happened here.

 1. When the script starts, the computer prints the question to the screen.

 2. The computer then waits for the user to enter the name of their website, and saves it.

 3. “Hello” prints to the screen, along with the name of the saved website.

 4. In the PyChram window, the script compiles and executes using Python.

 5. The script runs exactly as designed, before exiting.

This example shows a simple piece of code written in a code editor.

Why Codes Are Everywhere

The rapid technological advances we have witnessed over the last few decades have a far-reaching effect on how everything works. We have to look beneath the surface, where the most significant changes occur. Computers replace millions of man-hours and a warehouse of analog machines with systems that are faster, safer, and more reliable.

Since computers run on code, it's clear why it can be found everywhere. Computers will continue to replace outdated technology in everything from microwaves to power generation, and the presence of code in our daily lives will increase.

How Code Becomes Program

If you're completely new to code, you're probably still wondering how a script like the one above became the kind of program you're used to. In the image above, the window on the left is a tool for converting Python scripts into programs.

From no code to a finished program. This example is very simple, but it is how almost all coding works. Every day, people use the programming language they have learned, to write scripts, which will become the programs we all use.


So what is coding? Coding is basically a computer language used to develop applications, websites, and software. Without it, we would not have the key technologies we rely on like Facebook, smartphones, and the browsers we choose to view our favorite blogs. All of these technologies run using code.
