# What is a Linked List?
A linked list is a data structure that stores data in the form of a sequence of nodes. Each node holds _data_ along with a _forward pointer_ to the _next_ node in the list. 
 

As depicted in the illustration below, a linked list is formed by nodes that are connected like a chain.
