Programming and coding
Programming and coding are two terms that are often used interchangeably, but they actually have slightly different meanings.
Programming is the process of creating instructions for a computer to follow. These instructions are written in a programming language, which is a set of rules that define how the computer should interpret the instructions.
Coding is the act of writing code in a programming language. It is the most visible part of programming, and it is what most people think of when they hear the term "programming."
Here is a simple analogy to help you understand the difference between programming and coding:
- Imagine that you are a chef, and you are cooking a meal. The recipe is the programming language, and the steps in the recipe are the instructions. Cooking the meal is the coding.
- So, programming is the overall process of creating instructions for a computer to follow, while coding is the act of writing those instructions in a programming language.
Here are some examples of programming: All of these examples involve writing instructions for a computer to follow;
- Writing a web application that allows users to browse the internet
- Developing a mobile app that helps people track their fitness
- Creating a game that allows users to play against each other online
- Building a robot that can navigate a maze
Here are some examples of coding: All of these examples involve writing code in a programming language;
- Write a program to print "Hello, world!" to the console.
- Write a program to calculate the sum of two numbers.
- Write a program to check if a number is even or odd.
- Write a program to find the factorial of a number.
What do you need to get started with coding?
All you need to get started with coding is a computer and an internet connection of you are taking online course. You may also want to invest in a good text editor or IDE (integrated development environment).
A text editor is a program that allows you to write and edit code.
An IDE is a more powerful tool that provides additional features such as syntax highlighting, code completion, and debugging tools.
Finally we need;
- A system
- A text editor
- A compiler
1. System requirements
The minimum system requirements for coding are relatively low, but they will vary depending on the programming language you are using and the type of projects you are working on.
For basic coding like writing scripts, developing web pages, etc go with following specifications:
- Processor: Dual-core processor at 2GHz or higher
- RAM: 4GB of RAM or more
- Storage: 128GB of SSD storage or more (can be HHD)
- Operating system: Windows, macOS 10.15 or higher, or Linux
- Internet connection**
For more complex projects like developing mobile apps or games, then you need a system with more powerful specifications, such as:
- Processor: Quad-core processor at 3GHz or higher
- RAM: 8GB of RAM or more
- Storage: 512GB of SSD storage or more
- Graphics card: Dedicated graphics card with 2GB of VRAM or more
- Operating system: Windows, macOS 10.15 or higher, or Linux
In addition to the system requirements, you will also need to install the necessary software for coding, such as a text editor or IDE, a compiler or interpreter, and any other libraries or frameworks that you need for your project.
Here are some specific examples of systems that meet the minimum requirements for coding:
- Windows: Dell Inspiron 15 3000, HP 15-dy1036nr, Acer Aspire 5 A515-56G-52Z0
- Mac: MacBook Air, MacBook Pro, iMac
- Linux: Dell XPS 13 Developer Edition, System76 Lemur Pro, Purism Librem 15
If you are on a tight budget, you can also consider using a cloud-based IDE, such as CodeSandbox or Repl.it. This will allow you to code without having to install any software on your computer.
Note: No matter what system you choose, the most important thing is to start coding and practicing regularly. With time and effort, you can become a skilled coder and create amazing things.
2. Code Editor
A text editor, code editor, and IDE are all tools that can be used to write and edit code. However, they have different features and capabilities.
- Text editor: A text editor is a basic program that allows you to write and edit text files. It has features such as syntax highlighting, code completion, and debugging tools.
- Code editor: A code editor is a more advanced text editor that is specifically designed for coding. It has features such as syntax highlighting, code completion, code refactoring, and debugging tools.
- IDE: An IDE (integrated development environment) is a complete software development environment that includes a code editor, compiler, debugger, and other tools. It is designed to help you develop software applications more quickly and efficiently.
Which one should you use?
The best tool for you depends on your needs and experience. If you are a beginner, I recommend starting with a text editor. Once you have a good understanding of the basics of coding, you can move up to a code editor or IDE.
Here is a table that summarizes the key differences between text editors, code editors, and IDEs:
| Feature | Text editor | Code editor | IDE |

| Syntax highlighting | Yes | Yes | Yes |
| Code completion | Yes | Yes | Yes |
| Debugging tools | Basic | More advanced | Comprehensive |
| Other features | None | Code refactoring, unit testing | Compiler, debugger, version control integration, etc. |
| Best for | Beginners | Experienced coders | Software development teams |
| Examples | Sublime Text, Notepad++, Atom | Visual Studio Code, Eclipse, PyCharm | IntelliJ IDEA, Eclipse, Visual Studio |
3. Compiler
A compiler is a computer program that translates code written in one programming language (the source language) into another language (the target language).
The target language is often a low-level language, such as machine code or assembly language, which can be executed directly by a computer's CPU.
Compilers are used in a wide variety of software development projects, from building operating systems and embedded systems to developing web applications and mobile apps.
Here is a simplified example of how a compiler works:
- The programmer writes code in a source language, such as C++ or Java.
- The compiler reads the source code and analyzes it to check for syntax errors.
- The compiler then translates the source code into an intermediate representation (IR).
- The compiler then optimizes the IR to improve the performance of the target code.
- Finally, the compiler generates the target code, which is then executed by the computer.
Compilers play an important role in software development by automating the translation of source code into target code. This allows programmers to focus on writing high-level code that is easy to read and maintain, without having to worry about the low-level details of how the code will be executed by the computer.
Here are some examples of popular compilers:
- GCC: A compiler for C, C++, and Objective-C.
- Clang: A compiler for C, C++, Objective-C, and Swift.
- Java Compiler (javac): A compiler for Java.
- Python Compiler (pyc): A compiler for Python.
- .NET Compiler Platform (Roslyn): A compiler for C#, Visual Basic, and F#.
If you are interested in learning more about compilers, there are many resources available online and in libraries. You can also find many compiler tutorials and examples on GitHub.
