With the use of networks, people who live far apart and have never met can talk to each other any time on the computer screen. Interfaces which allow group discussions are called Bulletin Board Systems, or BBS for short.
透過網路，原本相隔萬里不認識的人，任何時間都可以在螢幕上對談，這種可以讓大家討論、聊天的功能，就稱為「電子佈告欄（Bulletin Board System）」，簡稱 BBS。
