Definition: way of organising and storing data so that they can be accessed and worked
with efficiently.
Importance:
Efficient data access and manipulation.
Reduced redundancy.
Improved data security.
Memory Allocation and Data Structures
Static Memory Allocation: memory is allocated at compile-time.
Dynamic Memory Allocation: memory is allocated during run-time.
Linked Lists: Concept and Important Operations
Concept:
Linear data structure.
Each element is a separate object.
Each element (that is, node) of a list consists of two items - the data and a reference to the
next node.
Important Operations:
Insertion.
Deletion.
Traversal.
Graphs and Their Representations
Concept:
Graphs are used to model many types of relationships and processes in real-world
situations.
Representations:
Adjacency Matrix.
Adjacency List.
Edge List.
Advanced Topics: Tries, Heaps, and Hash Tables
Tries:
A tree-like data structure that is used for representing associative arrays.
Heaps:
A specialised tree-based data structure which is used for maintaining a set of elements with
some order.
Hash Tables:
Data structure which stores data in an associative manner.
Trees in Data Structures
, Concept:
Hierarchical data structure.
Each node has a value and a list of references to other nodes (its children).
Important Operations:
Insertion.
Deletion.
Traversal.
Applications in Real-World Data Structures
Memory Management.
File Systems.
Databases.
Compilers and Interpreters.
Graphics Editors.
Web Browsers.

Linked Lists
A linked list is a linear data structure where each element is a separate object. Each element
(that is, node) of a list consists of two items - the data and a reference to the next node.
Important Operations
There are several operations that can be performed on linked lists, including:
