            14.5  Bulletin Board



            Bulletin Board System
            A Bulletin Board System, or BBS, is a computer system running software that allows users to
            connect and log in to the system using a terminal programme. Once logged in, a user can perform
            functions such as uploading and downloading software and data, reading news and bulletins, and
            exchanging messages with other users, either through electronic mail or in public message boards.
            Many BBSes also offer on-line games, in which users can compete with each other, and BBSes with
            multiple phone lines often provide chat rooms, allowing users to interact with each other.



              Notes  Originally BBSes were accessed only over a phone line using a modem, but by the
                    early 1990s some BBSes allowed access via a Telnet, packet switched network, or
                    packet radio connection.

            Ward Christensen coined the term “Bulletin Board System” as a reference to the traditional cork-
            and-pin bulletin board.

            Presentation

            BBSes were generally text-based, rather than GUI-based, and early BBSes conversed using the
            simple ASCII character set. However, some home computer manufacturers extended the ASCII
            character set to take advantage of the advanced color and graphics capabilities of their systems. BBS
            software authors included these extended character sets in their software, and terminal programme
            authors included the ability to display them when a compatible system was called. Atari’s native
            character set was known as ATASCII, while most Commodore BBSes supported PETSCII. PETSCII
            was also supported by the nationwide online service Quantum Link.
