9. Recursion

This is the process of a function calling itself. Recursion can be useful for solving problems that can be broken down into simpler subproblems.

10. Stack

It’s a last-in-first-out (LIFO) data structure. Elements are added and removed from only one end of the stack.

11. Queue

It’s a first-in, first-out (FIFO) data structure. Elements are added to the end of the queue and retrieved from the beginning.

12. Recursive Algorithm

This is an algorithm that uses recursion to solve a problem. For example, tree traversal algorithms often use recursive calls.

13. SQL (Structured Query Language)

It is a programming language used to manage and manipulate relational databases.

14. API (Application Programming Interface)

It is an interface provided by software to interact with other programs or components.

15. GIT

It is a distributed version control system used to track changes in a code base and manage collaborative development.

16. IDE (Integrated Development Environment)

It is software that makes it easier to develop, debug, and test programs.

17. Debugging

This is the process of investigating and correcting errors in software code. Debugging may involve the use of specialized tools to find and fix errors.

18. Algorithm

Algorithms are a sequence of steps performed to solve a problem or perform a specific operation. Algorithms are used to solve various programming problems.

19. Exception

An object that represents an error or unusual situation that occurs during program execution. Exceptions allow a program to handle errors and make it more robust.

20. Database

It’s an organized data repository where information is stored and managed. Databases are used to efficiently store and retrieve information.

21. Index

It is a data structure that organizes values ​​in a database to speed up searching and retrieving data.

22. Asynchronous Programming

This is an approach to writing programs where tasks are executed in parallel and independently. Asynchronous programming allows for the creation of responsive and efficient applications.

23. Thread

This is a separate execution path within a program. Threads allow multiple tasks to be executed in parallel and improve overall application performance.

24. Distributed Systems

These are systems in which computer resources and tasks are distributed across multiple computers or network nodes. Distributed systems allow for increased scalability and fault tolerance of applications.

25. REST (Representational State Transfer)

It is an architectural style for developing web services that uses standard HTTP protocols to exchange data between a client and a server.

26. MVC (Model-View-Controller)

This is a software architecture pattern that divides an application into three main components: model, view, and controller. MVC improves code structure and simplifies application development.

27. Hashing

Hashing is the process of converting fixed-length data into a fixed-size hash value. Hashing is used to uniquely identify data and for fast retrieval.

28. Bitwise Operations

These are operations performed on individual bits of numbers. Bitwise operations are useful for manipulating flags and bit fields.

29. Docker

Docker is a platform that allows you to package and run applications in isolated containers. It simplifies application deployment and scaling.

30. Refactoring

It is the process of changing the structure and organization of code to make it more understandable, maintainable, and efficient, without changing its functionality.

31. Memory Management

This is the process of managing the allocation and deallocation of memory during program execution. Memory management is important for efficient resource use and preventing memory leaks.

32. Deserialization

Deserialization is the process of converting serialized data back to its original format. Deserialization is used to reconstruct objects from data stored or transmitted over the network.

33. Regular Expressions

These are sequences of characters that define a pattern for searching and matching text. Regular expressions are widely used to process and analyze string data.

34. Sorting

This is the process of arranging elements in a given order. There are many sorting algorithms, such as bubble sort, insertion sort, and quicksort.

35. Design Pattern

This is a repeatable solution to a common problem in software development. Design patterns help create flexible, extensible, and readable code.

36. NoSQL

This is an approach to storing and processing data that doesn’t rely on traditional relational databases. NoSQL databases offer a flexible data schema and scalability for working with large volumes of information.

37. OOP (Object-Oriented Programming)

It’s a programming methodology in which programs are structured around objects that represent real-world or abstract entities. OOP allows for the creation of modular, reusable, and extensible code.

38. JSON (JavaScript Object Notation)

JSON is a data exchange format based on JavaScript syntax. JSON is often used to transfer data between client-side and server-side applications.

39. Compilation

This is the process of converting a program’s source code into machine code that can be executed by a computer. Compilation is usually performed before the program is run.

40. Virtualization

This is a technology that allows multiple operating systems or applications to run on a single computer or server. Virtualization improves resource efficiency and simplifies system management.

41. Cryptography

This is a field of science that deals with information security through encryption and decryption. Cryptography is used, for example, to ensure network security or data protection.

42. Emulation

Emulation is the process of creating software or hardware that simulates the behavior of another device or program. Emulation allows programs or games to run on different platforms.

43. CDN (Content Delivery Network)

A CDN is a network of servers located around the world to speed up content delivery to users. A CDN reduces latency and improves performance when working with websites or applications.

44. Deadlock

This is a situation where two or more program threads block each other and cannot continue execution. Deadlocks can lead to program freezing and incorrect operation.

45. Unit Test

This is the process of testing individual modules or functions in a program to ensure their correct operation. Unit tests are an important part of the software development process.

46. ​​Big O notation

It’s a way to evaluate the performance of algorithms in terms of execution time and resource usage. Big O notation helps programmers analyze and compare the efficiency of algorithms.

47. Multithreading

This is a program’s ability to execute multiple threads in parallel. Multithreading improves performance by allowing parallel tasks to be executed.

48. SIMD (Single Instruction, Multiple Data)

SIMD is a parallel data processing technique that allows a single instruction to be executed on multiple data elements simultaneously. SIMD is used to accelerate computations such as image and audio processing.

49. ORM (Object-Relational Mapping)

It is a programming technique that provides automatic mapping and interaction between object-oriented code and a relational database.

50. Encapsulation

This is a principle of object-oriented programming that groups data and methods that operate on that data within a class. Encapsulation ensures controlled access and data hiding.
