How is data stored in shooters?

Question

Game development

How are player data stored in already created online shooters?
For example in CSGO? There, on average, the frequency of sending data to the server is 64 times per second. Where and how is the data stored there?
In server RAM or where?

Answer 1

In dynamic online games, data is stored in two places:
If the player's computer data differs from the server data, the player is considered a cheater.
Something is stored in RAM (the current moment of the game), and something is stored on the disk (data that is not needed at this moment).
