Mark,
Before 1983, the ARPANET wasnât an internet, let alone The Internet. Each ARPANET connection required a host-specific interface (the âIMPâ) and simplex Network Control Protocol (NCP). NCP used users' email addresses, and routing had to be specified in advance within each NCP message.
I think you mean before 1982. TCP/IP was deployed starting in 1982. NCP was deprecated (removed from the ARPANET) January 1, 1983, but TCP/IP was implemented (and deployed) prior to that.
Then again there were IMPs fitted to various systems like TOPS-10, ITS, Vax/BSD Unix, IBM370, etc.
So was that really all that different from ethernet vs, oh, wi-fi or fiber today, you needed an adapter?
It really wasnât, but even if you just want to count from TCP/IP forward, 1983 isnât the correct date. 1983 was when we turned off NCP. It wasnât when we turned on TCP/IP. The turn on of TCP/IP occurred over several months, so thereâs no particular date that can be assigned to it. Owen
