From Wikipedia, the free encyclopedia. In computer science, a linked list is a linear collection of data elements, called nodes, each pointing to the next node by means of a pointer. It is a data structure consisting of a group of nodes which together represent a sequence.
A singly linked list is described above. A doubly linked list is a list that has two references, one to the next node and another to previous node. Another important type of a linked list is called a circular linked list where last node of the list points back to the first node (or the head) of the list.
