Explanation: 

Detailed explanation-1: -A linked list is a linear data structure that needs to be traversed starting from the head node until the end of the list. Unlike arrays, where random access is possible, linked list requires access to its nodes through sequential traversal.

Detailed explanation-2: -Each element in a linked list is called a node. A single node contains data and a pointer to the next node which helps in maintaining the structure of the list. The first node is called the head; it points to the first node of the list and helps us access every other element in the list.

Detailed explanation-3: -The first node in a linked list is called the Head or the Root node. The linked list will have a pointer that points to the head node to know where the list begins. The last node in a linked list has its next pointer set to null.
