In Windows, all installed applications go into the Program Files/Program Files(x86) of the hard-drive in which the application is installed on.
What is the equivalent in Linux or Ubuntu specifically?
When I install a program using APT, flatpacks, snaps or using manual methods such as .deb among others - where should I be installing these? Or do these methods automatically follow a convention?
Additional small question: Does the same convention apply to servers?
