Terms in programming

Understanding programming terminology is the first step to mastering the profession. It helps not only to understand materials but also to communicate effectively with colleagues, find solutions to problems, and read technical documentation.

In this article, you’ll find a programmer’s dictionary, organized by category, to serve as your guide.

Why is it important to understand the terminology?

1. Accelerates the learning process

When you understand terms, you absorb new technologies, methodologies, and concepts more quickly. For example, if you know what a “variable,” “function,” or “array” is, you won’t need to waste time repeating them.

2. Facilitates interaction with the team

In the world of development, communication between participants is essential. Programmers, designers, testers, and managers use specialized terminology to describe processes and solutions. Without knowledge of these terms, you will have difficulty interacting with your colleagues.

3. Understanding the context

There is often a specific context. For example, the word “compilation” in the context of Java or C++ development means converting source code into an executable file, but in other languages, this may not be the case.

4. Improves problem-solving ability

When you encounter a bug, it’s important to interpret error messages or logs correctly. Most of these messages contain specific terminology.

5. Simplifies the development of new technologies

Technology is constantly evolving, and to keep up with progress, you need to be prepared to quickly master new approaches. For example, if you’re already familiar with APIs, the transition to learning RESTful APIs will be significantly easier because you already understand how requests and responses work.

6. Creates confidence and professionalism

Feeling “professional maturity” can play an important role when looking for a job or advancing in your career.

7. Reading the documentation

The documentation contains specific terminology; without understanding it, you can miss important details or misunderstand the explanation.

8. Increases work efficiency

Modern development tools, such as IDEs, frameworks, and version control systems, use a variety of specialized terminology. To work effectively with them, it’s important to understand the meaning of various functions and commands. This will allow you to configure and use the tools to their full potential.

Basic terms

What is programming?

Computer programming is the process of creating instructions that a computer executes. These instructions, called code, can control devices, create websites, games, or apps.

Basic terms

• Script: A file containing commands to execute a program.
• Variable: a place to store data.
• Algorithm: a sequence of steps for solving a problem.
• Function: A block of code that performs a specific task.

Dictionary by category

• IDE (Integrated Development Environment): software for writing, editing, debugging, and testing.
• Framework: a set of ready-made tools and libraries that facilitate application development.
• Library: a collection of ready-made functions and methods that can be connected to a project to perform specific tasks.
• Compiler: A program that converts source code into executable machine code.
• Interpreter: A program that performs encoding line by line, without first converting it to machine code.
• Repository: A repository where a project’s source code resides, often used for collaborative design.
• Version Control: A system that records changes in coding, allowing you to revert to any previous version.
• Debugging: finding and fixing errors.
• Build: Combining source code, libraries, and resources into a single file or package to run a program.
• Testing: checking the functionality of a program or its individual components.

2. Programming languages

General:

• Variable: A named location for storing data.
• Condition: a test that causes the program to perform certain actions.
• Syntax: the writing rules for a specific programming language.
• Array: A data structure that stores multiple values ​​in a single object.
• Class: A template for creating objects in object-oriented programming.
• Object: an instance of a class containing data and methods.
• Method: A function that belongs to a particular class.

Specific languages:

• Python

  • Event: An action that occurs on a page (such as clicking a button).
  • Promise: An object representing the result of an asynchronous operation.
• Java
• • Interface: A contract that defines the methods that classes must implement.
  • Package: A group of classes and interfaces organized by functionality.

3. Tools, technologies

• API (Application Programming Interface): an interface that allows programs to interact with each other.
• Frontend: the visible part with which the user interacts.
• Backend: the server part where data processing and business logic occur.
• Full-stack: a developer who works with both the frontend and backend.
• DevOps: A set of practices that integrates development and operations to improve software quality.
• CI/CD (Continuous Integration / Continuous Delivery): automation of code build, testing, and deployment.
• Containerization: A technology for packaging an application and all its dependencies into a single container, such as Docker.
• Cloud Computing: Providing computing resources over the Internet.
• Virtual Machine: An emulation of a physical computer running inside another device.
• Serverless computing: A model in which the developer uses cloud resources without managing servers.

4. Development

• Agile: a flexible project management methodology focused on iterative development.
• Scrum: An Agile framework that includes sprints, planning, retrospectives, and daily meetings.
• Sprint: A period of time during which a team completes a specific set of tasks.
• Kanban: A project management method using visual boards.
• MVP (Minimum Viable Product): a minimum viable product that demonstrates key features.
• Roadmap: a product development plan that specifies tasks and deadlines for their completion.
• Refactoring: Improving existing code without changing its functionality.
• Technical Debt: Compromises in development that require correction in the future.
• Code Review: code review by another developer to improve its quality.

Typical mistakes

Helpful tips

1. Use IT glossaries

Consult online dictionaries or glossaries such as MDN Web Docs, Tech Terms to find precise definitions and their usage.

2. Learn terminology by category

Divide them into groups: fundamentals, programming languages, tools, and development processes. Start with the basic concepts and gradually move on to more complex ones.

3. Create your own dictionary

Write down new terms and their definitions. Refer back to your notes periodically and test your knowledge to reinforce the information.

4. Practice on real projects

Working on projects helps you learn terminology in real-world situations, which fosters a deeper understanding of its meaning.

5. Refer to video tutorials and courses

Interactive courses or video tutorials on platforms explain information with examples and practical tasks.

6. Join IT communities

Communicating with experienced specialists on forums or in communities helps you master terminology more quickly.

7. Repeat regularly

Use spaced repetition to improve your memorization. Apps like Anki will help you systematically review what you’ve learned.

8. Read the documentation

Official documentation, such as Python Docs or JavaScript MDN, contains detailed definitions and examples.

9. Analyze projects

Debugging bugs helps you understand the terms associated with specific problems and learn how to use them correctly.

10. Use associations

To remember complex definitions, you can associate them with real-world objects. For example, imagine a variable as a data storage box.

Conclusion

Programming terminology is the foundation for understanding development processes and effective communication in IT. The better you understand these terms, the easier it will be for you to learn, work, and grow in the profession. Regularly learn new terminology, read official documents, and apply your knowledge in practice.
