What Exactly is program installation?

Hello all.

When a user wants to install a game in windows the user downloads "the game" from the website and installs it. 

When someone in Linux wants to install a cool text editor he/she probably uses 'apt install something'.

What the installation process actually does? 

Is it something like "the installation process extracts some compiled programs to a specific place (directory) and when the user runs that program it locates those sources in that specific place" or it is something completely different?

You're exactly right. When you install a program, it'll likely insert a binary into some location, and do some other setup specific to the install (i.e. Insert some config file in your home directory). 

The location on linux is `/usr/bin/`, on windows is `C:\Program Files`.
