I first used the Arpanet in 1985, communicating from Portland to Berkeley via email. The only people who could access the Arpanet back then worked at high-tech companies like Tektronix, Boeing, and major research universities like Berkeley. No real-time connections ... the mainframe computers talked to each other via dial-up connections at night, so the reply to your email would take the next day. The public didn't get access to the Internet until about 1993 or so, and you could choose an ISP and get a 9600 baud modem to access it. Modems topped out at 56000 baud, depending on line quality, which could change moment by moment.
4:26 That's the first computer I ever used, an HP 2000C minicomputer connected via dial-up modem to a Teletype 33 terminal in 1974. It had an HP 2000 BASIC interpreter and ran a computer game, TREK73. The BASIC source code can be found online.
My mind was blown when in 2006 we got DSL - I had internet while mom was using the phone! Up to that point, we had dial-up and only 1 phone line at home, so that meant no internet until the evening and weekends because mom wanted the phone during the day. (It also meant that if you wanted to get your siblings off the internet, all you had to do was pick up the phone and blow into the phone to create enough noise to confuse the computer's modem and thus cause it to disconnect. XD ). Now I have fiber optic internet to my home - how far we've come thanks to the combined efforts of millions of men and women.
@EverythingButTheCode exactly! Hopefully the generation after us sees even more cool stuff. We all need something to look forward to. We live in such a negative time now.
Electromagnets sound more complicated than they really are. Watch how easy it is to make one: th-cam.com/video/Wm9_DqQKmd0/w-d-xo.html
I enjoyed that video, Alexandra! Lots of great information packaged in a neat video. I didn’t know DSL was still around!
Thank you!!
I learned a lot from this
fiber optic cable, high speed internet access, lotta money in this shit

It’s crazy that we’ve been able to experience all of this in one lifetime!
