BBS is an acronym for bulletin board system and it can be defined as an application or computer system which is typically used for the sharing and dissemination of user informations or data such as messages or files over a network. It is generally considered to be an alternative to the world wide web (www) in the 1980s and early 1990s before the advancement of the internet.
