It seems that you have no clue about the subject.
French is a romance language (use wikipedia to understand what it means) and it is a basic feature of this language to use latin to coin its own words (https://en.wikipedia.org/wiki/Vulgar_Latin). During the XVI century, French took the habit to also use greek roots to coin new words. It is just the english (a germanic language that has nothing to do with latin) that imported french words and then the french way to create word from latin and greek roots. (The motto of the queen of England is even in french).
Take a simple exemple: Geography this word was made in french from the greek words ge and graphy (earth and to write) this word was then imported in the english language during the XVI century.
Most of the word you refer are the same in all romance language (French, Italian, Spanish, etc.) for the same reason.
Of course modern French is not the same as latin but it is the same as for Italian and Spanish. Even modern Greek is very different from the classical version.
By the way in french a computer is "ordinateur".
