Lesson 1: Introduction to Data Structure & Algorithms

Vocabulary flashcards defining fundamental concepts of data structures, linear and non-linear categories, and core linear data structures including Array, Linked List, Stack, and Queue.

Data Structure

A specialized format for organizing, processing, storing, and retrieving data efficiently in a computer's memory.

Linear Data Structures

Data structures organized in sequential order.

Non-Linear Data Structures

Data structures organized in hierarchical or interconnected order.

Array

A fixed-size collection of identical data types stored in continuous memory slots.

Linked List

Sequential elements (nodes) where each node points to the next node in memory.

Stack

A linear data structure using LIFO (Last In, First Out) where elements are added and removed from the same end.

Queue

A linear data structure using FIFO (First In, First Out) where elements enter at the back and exit from the front.

LIFO

Last In, First Out; the operating mechanism of a stack where elements are added and removed from the same end.

FIFO

First In, First Out; the operating mechanism of a queue where elements enter at the back and exit from the front.
