Introduction to Linked List
Neso Academy・2 minutes read
The presentation explains linked lists and how they arrange student names alphabetically, discussing memory maintenance using array or linked list data structures, different types of linked lists, node structure with data and link parts, and accessing nodes using a 'head' pointer.
Insights
- Linked lists can be organized in various ways, such as single, doubly, or circular linked lists, each offering unique advantages and applications in data management.
- Accessing nodes in a linked list relies on a pointer, often named 'head', which serves as the starting point for traversing the list and accessing subsequent nodes efficiently.

Understanding Linked Lists: Types, Nodes, Accessing, Maintenance
- Introduction to Linked List: Presentation focuses on explaining what a linked list is and how it looks like, with the goal of arranging student names alphabetically.
- Memory Maintenance: Two ways to maintain a list in memory are discussed - using array data structure or linked list data structure.
- Types of Linked Lists: Different types of linked lists are introduced, including single linked list, doubly linked list, and circular linked list.
- Node Structure: Nodes in a linked list consist of data and link parts, with the link containing the address of the next node in the list.
- Accessing Linked List: Accessing the first node of a linked list requires a pointer, typically named 'head', which holds the address of the first node, allowing access to subsequent nodes.
