Consists of nodes, each containing data and a reference to the next node.
Types include singly linked lists, doubly linked lists, and circular linked lists.
Singly linked list example: 1 -> 2 -> 3 -> NULL.
Doubly linked list example: NULL <- 1 <-> 2 <-> 3 -> NULL.
Circular linked list example: 1 -> 2 -> 3 -> 1 (last node points to the first).
Dynamic size, efficient insertions/deletions compared to arrays.
