"Linked lists are a fundamental data structure, used to implement queues, stacks, and other abstract data types."

A linear collection of data elements, whose order is not given by their physical placement in memory.

"In a linked list, each element points to the next, making it a dynamic data structure that allows efficient insertions and deletions."
