located on ：一般不会用於人身上。
例句：This queue manager should be located on another node.
located at ：通常是用於有精确的地址的情况。
例句：Located at the mouth of the Mississippi River, this city is renowned for its jazz music, wild nightlifeand Cajun cuisine.

例句：The capital city, Nicosia, is located to the north-east of the centre of the island.
