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.

Stacks
Stacks are a fundamental data structure in computer science that follow the Last In, First Out (LIFO) principle. Elements are added and removed from the top, resembling a stack of plates. This structure is commonly used for function call management, expression evaluation, and undo operations in programs.
Queues
Queues are a data structure that follows the First In First Out (FIFO) principle. They allow elements to be inserted at the back and removed from the front. Similar to waiting in a line, elements are processed in the order they arrive. Queues are used in various computing applications for managing data.
Linked Lists
A linked list is a data structure consisting of nodes where each node contains a data element and a reference or link to the next node in the sequence. It allows dynamic memory allocation and efficient element insertion and deletion. Linked lists can be singly or doubly linked.
Arrays
Arrays are a data structure in programming that store a collection of elements, such as numbers or strings, under a single variable name. Each element in an array is accessed by its index, which represents its position in the array. Arrays provide a convenient way to organize and manipulate data.
Pointers
Pointers are variables that store memory addresses instead of actual data. They are used to indirectly access and manipulate data in programming languages like C and C++. Pointers allow for dynamic memory allocation, efficient memory management, and the ability to create complex data structures.
Memory Allocation
Memory allocation is the process of reserving and managing memory space for programs to store and access data during runtime. It involves assigning memory for variables, objects, and functions dynamically. Proper memory allocation is essential for efficient program execution and preventing memory-related errors like memory leaks and crashes.
Bit Manipulation
Bit manipulation involves manipulating individual bits within a binary sequence to perform operations like setting, clearing, or toggling. It is commonly used in optimizing code for tasks like counting bits, checking parity, or performing bitwise operations such as AND, OR, and XOR, efficiently at the machine level.
Boolean Logic
Boolean logic is a fundamental concept in computer science and mathematics that deals with truth values. It consists of two possible values: true and false. These values are used in logic gates to perform logical operations, making decisions, and controlling the flow of programs based on conditions being met.
Mathematical Foundations
Mathematical Foundations is a branch of mathematics focusing on the fundamental theories and principles that form the basis for other mathematical concepts. It includes topics such as set theory, logic, proofs, and abstract algebra. Understanding these foundations is essential for building a solid understanding of advanced mathematical topics.
