Simply so, what is head node in linked list?
A linked list is a linear data structure where each element is a separate object. Each element (we will call it a node) of a list is comprising of two items - the data and a reference to the next node. The last node has a reference to null. The entry point into a linked list is called the head of the list.
One may also ask, what is the head node? A head node is setup to be the launching point for jobs running on the cluster. A head node is often nothing more than a simply configured system that is configured to act as a middle point between the actual cluster and the outside network.

Linked lists are linear data structures that hold data in individual objects called nodes. These nodes hold both the data and a reference to the next node in the list. Linked lists are often used because of their efficient insertion and deletion.
