Early 80s, domination of propriatery network hardware and protocols:
Apple: AppleTalk
Digital: DECnet
IBM Mainframes: Systems Network Architecture (SNA)
In early-mid 80s, IBM and Sytec developed PC Network to connect PC computers on a local network.
Network Basic Input Output System (NetBIOS) was the software interface to
the PC Network hardware. It offered a set of commands that could control
the hardware, establish and delete sessions, transfer data, etc.
Non TCP/IP based yet, local network support only.
NetBIOS names are not DNS names.

For example, the computers have NetBIOS names DANY and BOSS
