A linked list can only have integers in its nodes.

The maximum number of nodes that a linked list can contain is specified when that linked list is first created.

A linked list can physically grow as long as there is memory, but doesn't really shrink as the released nodes remain available for the list.

A linked list can contain in its nodes any kind of elements because instead of the element, the node has a reference to the element somewhere else.
