@mur2501 @karin_artss there are what you might call "thin" applications, especially those that you download to your phone, which don't really do much unless they speak to a server, such as Facebook's servers, because that's where the data is. one would typically call a whole such application a "front-end" for the service. there are multiple levels here, bit like an onion... can get confusing.
@karin_artss @mur2501 this breed of Internet-reliant apps is relatively new and weren't very prominent prior to the invention of the smartphone, which is how we ended up with these somewhat overlapping naming schemes.
