Yes, the previous connection is automatically broken (overwritten), but the node is pointed to may still exist in memory
How it works:
node1.next = node3 #previously was node2The printer is overwritten - node1.next now points to node3. The reference to node2 is gone from node1
The old node(node2) still exist in memory , unless there are no other references to it
Garbage collection - If nothing else points to node2, it becomes eligible for garbage collection
Changing a pointer overwrites the old value but doesn't automatically delete the object it pointed to
