Back then it was only connected to military and research universities. Dial up was possible with incredibly slow stand along modems with a personal computer (typically 4 or 8 Kbyte memory). I had a suitable computer and modem by 1985. There wasn't much on it back in those days...
I also got a chance to watch all the traffic going through the universities node point on the network. That was educational.
During 1983, ArpaNet adopted TCP/IP protocol making it a network of networks. I started transferring email and supporting documentation from the US down to Australia for our defense industry project partners. The instant response was critical to keep coding/test activities synchronized. A year later, I went down for a two year assignment on the project. I never dreamed ArpaNet -> Internet growth would explode like it did.
TCP/IP was being tested in 1975-81 as best I know (I recall the discussions on it in 1981), and was first adopted for mainstream use in in 1982 with the formation of what was known as SATNET.
The US Military adopted TCP/IP for all of the defense needs in 1983, using the existing arpanet that existed.
It actually took a couple of years for all users on the arpanet to fully switch to TCP/IP from what Wiki identifies as the previous "Network Control Program" (NCP). Many computing centers allow both NCP and TCP/IP for a while.
With arpanet now using TCP/IP SATNET merged with it, and new branches started to be build.
It sure was an interesting time. I used to be able to recover my email using basic TCP/IP commands as recently as 1990 when remote from my home. I've since forgotten those commands; and its my understanding that the internet has now moved past the old TCP/IP (they have newer versions of it - keeping the name even if the structure has changed); leaving classic TCP/IP in the history bin just as it left NCP in the history bin.
Well of course token ring architectures, like those used in massively parallel relational databases have never used TCP/IP. But for the most part, the seven layer (originally 4 layer) OSI model is still intact. The entire World Wide Web made a very graceful transition to IPv6 about 10 years ago and the whole standard continues to evolve with special headers, point-to-point-tunneling protocol, etc.
Actually, network evolution is one of the smoothest most sensible foundations of the cyber universe. To be sure, Telnet is dead. My telnet manual is in the same junk drawer as my plastic slide rule from the sixties.
As part of some of our computer/engineering classes we had to get data sets from the University of Chicago and University of Minnesota. Madison had data sets that the other university students had to get for some of their projects as well.
I learned how to find out what data and papers were available on different sites - and download them... in 1981/82.
Look up "arpanet" on Wiki for the real history of the backbone of the internet.
Here's what you need to know: Someone sitting on a node point (or able to attach to it) essentially can read in plain text anything that is not encrypted.
Also, the simpler encryption is not that hard to break either (I'm not going to go into details on that).
The internet was built for reliability - not security. It takes a lot of real work to make it secure.
The concept of Internet Security is almost an oxymoron.
There's some security these days with the most common software. But, you really have to work at really having secure communications - and privacy too.
When did you first start using the internet?

1981 as part of a uni project that sounds so cool. You were a pioneer 1995 when I was 17 here

Not a pioneer. Those people were there in the very late 1960's and early 1970's (look up "arpanet" on Wiki).
Just an engineering student that was more inquisitive than just getting the required data sets from other universities for assigned projects.

Oh wow 60's and 70's I will look that up sounds interesting thank you.
Oh wow, Stanford?

University of Wisconsin - Madison.
As part of some of our computer/engineering classes we had to get data sets from the University of Chicago and University of Minnesota. Madison had data sets that the other university students had to get for some of their projects as well.
I learned how to find out what data and papers were available on different sites - and download them... in 1981/82.

I want to hear the details of the second part

Also, Look up "packet sniffers"
DSL is often done in a ring arrangement and someone with a packet sniffer can read all the internet traffic from any other people on the ring.
Other networks have other ways to access the data.
