Operating Systems: Crash Course Computer Science #18

So as you may have noticed from last episode, computers keep getting faster and faster, and by the start of the 1950s they had gotten so fast that it often took longer to manually load programs via punch cards than to actually run them! The solution was the operating system (or OS), which is just a program with special privileges that allows it to run and manage other programs. So today, we’re going to trace the development of operating systems from the Multics and Atlas Supervisor to Unix and MS-DOS, and take at look at how these systems heavily influenced popular OSes like Linux, Windows, MacOS, and Android that we use today.

11:18 where IT began "Have you tried turning it off and on again?"

Thank you to the presenter. She did an amazing job of breaking down a technical topic into a fun and interesting one in a very effective short time.

As a Linux kernel developer, I watched the whole video planning to point out all the mistakes and errors. Frustratingly, there weren't any. Well done +CrashCourse, you've ruined my fun ;)

I love this show! I've learned so much from it, especially the episodes explaining all the details of how transistors come together to make logic gates, and how those actually come together to make all the different basic parts of a cpu. I've known about logic gates and the way they work (their "rules") for a long time, but never found a video series explaining how they're applied in practice that was so easy to absorb and so well organized. Keep making more episodes plz :)

Who else had a brief moment of panic at 11:38 ? I will never forget the sound of old windows giving me a freaking error!

CrashCourse, you have helped me with satisfying my curiosity for a large number of fields. Thanks for all this.

Currently starting the transition from clinical psychology to tech and I could not be more pleased with this channel and series! It was wonderful during grad school for psychology and now for technology as I look for programs, I already completed some work though Coursera but this really helps lay a foundation and fill in gaps of specific skills I am currently learning.

Am I the only one who burst into laughter when she said "plug and pray" 😂😂

These videos have taught me more than my college professors for the past 2 semesters. THANK YOU, and excellent work on these videos!

[dippy]

I am thoroughly enjoying the computer science crash course series. Great work Kerryanne and Crash Course.

Aww! You guys put in clips from Bits & Bytes! I loved that series! So happy to see it surface here in some way. Thank you!

As someone who has worked with mainframe tech produced in the 1960's and well used to a format loop on a printer you soon get to learn that everything is an evolution from something before it and thus long term you just see it as X with Y.

The thing is that most people today would run a mile having to do what we used to have to do, bringing in paper to the print room by 3-4 boxes which was 190+ pounds in weight.

Oh the stories of the good old days where throwing a write protect ring could down an entire place if it hit the emergency power off.

computers are rocks we tricked to think

[HugoCornellier]

Excellent presenter. I’ve specifically come back to her videos because she’s helped me during Uni!

[markh]

Omg! I haven't watched this yet but I'm already super excited for the Reboot reference on the title card!

[lantishaledane]

"Things weren't exactly PLUG-and-PLAY back then...more of PLUG-and-PRAY." :D :D :D

[SunOfNight]

Even after all these years since seeing it last, the blue screen sound at @11:39 is still familiar and dreaded.

Quote of the episode:

"This was clearly terrible"

[congaspy]

"-blue screen of death-DUN" *heart attack*

Thank you Unix for being the granddaddy of Linux. We salute your efficiency, speed, and power.
