What is stored in the first node of a linked list?

The first node of a linked list contains:

• A value (data), which represents the content of this node.
• A reference (pointer) to the next node in the list.

The first node is the starting point of the list, through which all other nodes can be accessed by following the links from one node to the next. If the list is empty, there is no first node (the reference to it is null).
