Pretérito perfecto / compuesto

Hola Douglas

There is no difference at all, the present perfect (in English) is sometimes called El Pretérito Perfecto and sometimes El Pretérito Perfecto Compuesto. The latter is to differentiate it from "El Pretérito Perfecto Simple" which is the "past simple" ( I did, you did, he did...).

Kwiziq has a table where you can see all different names used for different tenses. Have a look here. I hope this helps.
