locally installed software - software that is installed on your device's internal storage
software as a service (SaaS) - software that's delivered on demand over the internet
subscription software - a model whereby the user pays a fee to use the software. The software is

restore point - a type of backup that doesn't affect your personal data files but saves all the apps,
