installation - How local Databases in apps works?

Question

When I was in school, they teach me the basic stuff like create a DataBase, and Select, Insert, Update....that kind of querys, but they never teach us what is a Database, how does it work?, and now I've several questions about it, especially when you are trying to release an application.

So I learned that theres is Local and external DataBases, I don't have any big question about external ones, but how Local databases work?, let me explain it.

I know a Database manager is like a program (service) that arrange, search, etc. data in a file, but for example: If I had 2 applications in my computer and both have Local Databases, each one has to run his own service? or is only one service? if I want to develop a desk and mobile app and the database is in a local database, how can they share same database?.

When you install an application with local database, do you install the database manager as well?

If you are in the same local network, can you access to this local databases?

Can another app just access to that local database of another app if it is in the same local network?

or local databeses only can be used in its own application

if you can tell me how local databases work and how they interact with S.O. and the installation process it will be helpful thank you.
