A linked list is a set of LINEAR elements where each element has an INDEX or a pointer that INDICATES the next element. An element of a linked list is referred to as a node. A node will store data as well as a pointer/index about the next node in the set. There are different types of linked lists. For example, a circular linked list is a list where the last element of the list points to the first element of the list, forming an unbroken chain of data. A double linked list is a list in which every node stores the index of the node on either SIDE of it.
