Lylian,
You can use the two carriers mentioned above that are part of DCS however the Supercarrier Mod has additional features that make carrier operations more immersive.   You will also need one of the carrier based aircraft mods to perform launches and landings similar to real life such as the F-18 Hornet.
As you say you are new and may not want to make investments until you learn more about DCS there are a lot of user mods that are free and are also carrier operation suitable.  The leading user mod is the Community A4 Skyhawk mod.  There is also a T-45 trainer aircraft which is also free.  Both are detailed and user flyable.  VSN also has a user flyable F4B Phantom mod which is free and challenging.  The list goes on from there however all are free.  The list for AI only mods is even larger.
For carriers that allow you to land and launch you can also download free user mods.   Cuesta Brothers has two carriers, the Charles De Gaul and the Clemenceau (Eric and Patrick, sorry if I mis-spelled the ship names).  I use the Clemenceau the most as there are alot of add ons that enhance it and it is a close approximation to an updated Essex class boat.
You can search the forums by typing in a key word based on what I wrote above and you should be able to find links to the downloads.   All are slightly different in key commands so read the READ ME file for instructions, look up the assorted manuals that others have published, and also read through the posts to find answers to bugs, challenges, updates, and tips.   I am wiling to bet any questions you come up with have been asked, disected, and resolved already.
