All of this is from the mid 90's I think, so 30 years ago.
Before that, computers were generally not networked at all, or if they were it was netware (A world of suits), to share printers and storage, or possibly some telecom standard connection to run SNA to a mainframe (blue suits), or of course a modem to BBS for home users, or connecting to small business servers etc, which I remember well.
