'single linked' is just that: one *link* pointer in each list element.
nothing said about how many eternal (head, tail, body, intestines)
pointers exist *oustide* the list element.

a double-linked-list has two link pointers in each list element. (and
again, an unspecified amount of external pointers to list elements).
this is habdy when you must (often) remove an element from the middle of
the list.
