user16194: I am new to chess. I read about FIDE so my question is: How can I
can play in a FIDE tournament or become a FIDE-rated player?
Is there any online process for that, or something else? Right now I only know
about FIDE and not much about their process. Someone told me about FIDE but he was not very clear about them.

user17004: The International Chess Federation (FIDE) has several types of FIDE rating. The easiest FIDE rating to get is the online FIDE rating.  For that purpose, FIDE has a website that is relative cheap because you only need to pay 25 Euros per year (25-30 U.S. Dollars).
These are the most important links:

user12873: To get a FIDE rating, all you need to do is play in a few FIDE rated tournaments. Many big open tournaments with lots of players are FIDE rated, so those would be a good bet. You can find these tournaments by just searching on Google "Chess Tournaments in x" where x is the region you live.
There is no online sign-up process necessary. Once you play 9 FIDE-rated games and score at least 3/9 (unless the rules have changed) then you'll have a FIDE rating.

How can I can play in a FIDE tournament

In exactly the same way you would a non-FIDE rated tournament. First enter. Then play.

How can I can become a FIDE-rated player?

To get a FIDE rating you need to score at least one draw against at least 5 FIDE rated opponents in FIDE rated tournaments with a performance rating of at least 1000 over a period of not more than 26 months.
