What to do with cms?

Question

CMS

Please tell me (I ask only without: "contact the programmers") when writing code for cms, for example, user authorization, these files are uploaded to the host like other html, css, js, php and TD. Or is it from the area of ​​\u200b\u200bcreating your own server?
In order to have access to the database to add people to this very database. I'm sorry if this is a dumb question, but I just want to understand as I'm new to this :)

Answer 1

depending on the project, they can be on the same server or on different ones.
CMS is essentially a wrapper for code.
accordingly, the written code must understand how to access the database - locally or to some other server.
If you take a ready-made CMS and add some functions to it, then the files are usually located in the same place as the CMS
