Transactions
Transactions in programming refer to a sequence of operations that must be executed together as a single unit. In database management, a transaction ensures the integrity of data by either completing all operations successfully or rolling back changes if an error occurs, maintaining data consistency and reliability.

Algorithm Complexity
Algorithm complexity measures how the resources required for an algorithm to solve a problem grow as the size of the input increases. It quantifies the efficiency of an algorithm in terms of time and space. Common complexities include O(1) constant time, O(n) linear time, and O(n^2) quadratic time.
Data Structures
Data Structures are ways to organize and store data efficiently in a computer so that it can be easily accessed and manipulated. They include arrays, linked lists, trees, graphs, and more. Understanding data structures is crucial for writing efficient algorithms and designing effective software solutions.
Big O Notation
Big O Notation is a way to analyze the time complexity of algorithms. It describes the worst-case scenario for how the runtime of an algorithm grows as the input size increases. It provides a ballpark estimate of how efficient an algorithm is, allowing for comparison and optimization of different algorithms.
Recursion
Recursion in programming is a technique where a function calls itself to solve a smaller version of the problem. It involves breaking down a problem into smaller, simpler instances until a base case is reached. Recursion can be powerful for solving problems involving repetitive structure or branching logic efficiently.
Sorting Algorithms
Sorting algorithms are methods used to arrange a collection of items in a specific order. They are essential in computer science for organizing data efficiently. Different sorting algorithms, such as bubble sort, merge sort, and quicksort, have varying complexities and are chosen based on specific requirements and constraints.
Searching Algorithms
Searching algorithms are methods used to find a specific item in a collection of data. Algorithms like linear search and binary search are commonly employed to efficiently locate elements in lists, arrays, or other data structures. The goal is to quickly determine if a desired item exists in the dataset.
Graph Theory
Graph Theory is a branch of mathematics that deals with the study of graphs, which are mathematical structures used to model pairwise relationships between objects. Nodes represent objects, while edges connect pairs of objects. Graph Theory is utilized in various fields like computer science, social networks, and transportation systems.
Binary Trees
Binary trees are hierarchical data structures consisting of nodes, each of which has at most two child nodes, left and right. The top node is called the root. Binary trees are used to efficiently store and search data in computer science, with operations like insertion, deletion, and traversal.
Hash Tables
Hash tables are data structures that store key-value pairs. They use a hash function to quickly compute an index where the data can be stored and retrieved in constant time. This provides fast access to values based on their keys, making hash tables efficient for search and retrieval operations.
