I know this is old, but if you look at the code in the original DOS, they stole a lot including loadable drivers. There is even a residual variable instance counter as a hook for multi-user.
Easy-to-understand visuals, clear-cut explanations, a solid overview of the history, and some banger music. High-quality content in my book. Studying for a system-level programming midterm, but will check out your other videos afterward!
Just started learning about all this stuff well after college since I am looking to change careers and explore my interest in programming. Really appreciate this video!!
Your first photo shows the card punchers. I write my first COBOL program at the community college in Spring of 1982 on one of those machines. I think the computer was an IBM 4341. The card punchers were replaced the next quarter with dumb terminals. I wish I kept a deck of cards and a colored bar printout.
I know that it is an OS but I find it hard to visualize it. Like, OK, it is an operating system, but what about graphics and what not? I mean, what it >>looked
Home computers didn’t get a gui until the 80’s really, this is a decade older. Just open a Linux terminal and you have an idea of what it was like. Of course, in the very beginning they weren’t using terminals either, it was punch cards
@@tylerdean980 Unix supported terminals from the very beginning. These were mostly electromechanical teleprinters in the early 70s, as CRT-based “glass ttys” weren't that common back then.
This is a great and informative video I am watching this to learn and understand more about coding and the lures of everything great video man keep the good work
Not only is the mach kernel of Nextstep, Openstep, and macOS, obviously, since macOS version 10 and following came from Nextstep, but macOS IS a Unix operating system, and has been such since certified by The Open Group, who owns the Unix trademark, as far back as 2008 or 2011.
3:00 Eight Edition UNIX (UNIX v8) is in the wrong place on that tree. Rob Pike wrote that the history of UNIX leaves out Bell Labs research UNIX after version 7 as if it never happened. Did you know that Dennis Ritchie wrote symbolic links for UNIX v8 and his code was added to BSD? Did you know that there was a Datakit based network called XUNET that was contemporaneous with the ARPANET and XUNET connected Bell Labs with the University of California at Berkeley (UCB) where BSD came from?
MacOS is Unix at core and this is clear when working with a terminal app in Mac. iOS and iPadOS are also based on Darwin which is Apple's unix core. I think MaC is the best OS for those who can't decide between Windows and Linux. It has the best of the both worlds. And Homebrew is a great package manager for Mac.
Hello and thank for this great video! Can I buy a computer with an operating system which is neither GNU/Linux, nor macOS, nor Windows but which is Unix? Which operating system could that be?
You eventually explained why whole microsoft windows os crashes once it's file explorer crashes. It's because of dos(disc operating system), microsoft than used msdos(microsoft disk operating system). Whole os orient around file exploration (i mean windows file explorer). While on unix or linux even if you don't have a file explorer like thunar or dolphin your os still works.
Mac ks , since 10.5, is unix, ie at has been sertified as such by the open group thatare thevuwners of the unix trademark. So osx is more than derived from unix, it 'is Unix, linux however is not. But both oses are posix compliant. And yes indid react to the osx comment before warhing thus entire exelent video my bad)
And, this man's chart has FreeBSD thereon, but legally it is not Unix, because it did not pay the $100 000 certification fee to The Open Group. This presenter needs to do a bit more careful research before touting what he knows. He's only partially correct on certain points.
Cute summary ... but I guess I've used most of the major (real) UNIXes(and Linuxes) and all the other real OSes (primarily TOPS-10, VMS) ... and quite a few (awful) OSes ... (including Windows/DOS, NOS, KRONOS,...) ... so I have a pretty good overview. Without DEC, we would probably not have UNIX.
Windows is not inspired by UNIX, because Dave Cutler, the father of Windows, came from DEC and VAX / VMS, and is a notorious UNIX hater (and proud of it). VMS is nothing like UNIX at all. There is only one open source, freeware, canonical UNIX operating system directly descended from the original UNIX: illumos, being a fork of OpenSolaris, being an open source version of what was to become Solaris 11, being a direct descendent of AT&T System V Release 4.0 UNIX.
Unix is not available in modern form, best to use Linux or BSD. But it is much more secure than windows because it uses file permissions and has privilege levels that are more granular than windows. And it actually requires a password to install things by default, that alone is what causes 80% of windows infections.
I started my engineering career with Unix. First on Silicon Graphics Indigo 2s, the Sun, then HPs. Then, one company had switched over to MS Windows PCs when I started there and I had no idea how to use a Windows PC. I had had 7 years engineering experience, been to university, couldn't use a Windows PC. 😆 I hate MS Windows to this day; you seem to be always fighting it.

Unix still matters: iOS and MacOS are Unix (BSD Unix). Solaris and other operating systems used in the scientific community are Unix. Video title is correct.
Unix does NOT matter today. Unix went down with the Unix wars and the successor of it is Linux. Linux is the ruling operating system (I know it's not one operating system, but a family based on the same kernel) everywhere, except personal computers, where the ruling is Windows and probably MacOS. There is no Unix, just in history. But in history, there are other important systems like CP/M, which is the system that inspired the DOS->Windows line.
Mac OS is Unix based and is even POSIX compliant. Unix used to matter more, but its ideas of simplicity, worse is better, and modularity prevail. It is the world's most successful computer virus.
But Macintosh is another winner who arose from the Unix wars who dominates personal computer market. And as the author of video showed - actually Bill Gates (thus Windows in a way) also was one of the Unix wars participants, but after trying its stand in Unix like systems decided to create a completely different OS architecture. But we could say that that is also an outcome of Unix wars. So the winners of the Unix wars are all the modern OS giants - Linux, Macintosh and Windows

1:22 Ken Thompson circa 1970: "I'm doing an operating system (just a hobby, won't be big and professional like multics) for PDP-7."
Great video! I‘m reading a book about Linux right now and a part of it is the history of Unix and this video really helped me understand it better. :D

3:04 what is this image? Where is it?
Unix = C
Microsoft Windows = C:
Linux = / 👈 slash or solidus symbol, very simple and great! 😎
I wonder if that’s why that command button is so important on Mac?
AmigaOS (Workbench) is based on Minix too!
That tree is fantastic!
bro this is amazing
macOS is a certified Unix OS
Thanks 👍
Unix Csh was ripped off by CPM and CPM was ripped off by DOS.
They literally chose the 8086 because there was a version of CPM for the 8080 & 8086.

My pleasure - thanks for watching
Thanks a lot brother
You missed the opportunity to link Android (being Linux at its core) and iOS (which is also based on Darwin, just like macOS).
Any Linux can be Unix if it becomes certified as such by The Open Group. One Linux is Unix. Only one.
unix-like is the dark souls of the souls-like
explained it well
Please tell me you made a video about c programing
Thanks 🙏
Thanks, Morty.
As a developer that uses macOS, UNIX, NeXT history and macOS roots become apparent straight away NSObject 🤔 NeXT Step
I don't understand why everyone is giving these positive comments but nothing in the title was ever answered in the video
And, this man's chart has FreeBSD thereon, but legally it is not Unix, because it did not pay the $100 000 certification fee to The Open Group. This presenter needs to do a bit more careful research before touting what he knows. He's only partially correct on certain points.
Technically you are right, but that fact doesn't take away the main message of this video.
Great video, thank you! :)
Watch the computer cronicals episodes about Unix with garry Kildal who created Dos.
Cute summary ... but I guess I've used most of the major (real) UNIXes(and Linuxes) and all the other real OSes (primarily TOPS-10, VMS) ... and quite a few (awful) OSes ... (including Windows/DOS, NOS, KRONOS,...) ... so I have a pretty good overview. Without DEC, we would probably not have UNIX.
how's DOS/Windows awful?
Windows is not inspired by UNIX, because Dave Cutler, the father of Windows, came from DEC and VAX / VMS, and is a notorious UNIX hater (and proud of it). VMS is nothing like UNIX at all. There is only one open source, freeware, canonical UNIX operating system directly descended from the original UNIX: illumos, being a fork of OpenSolaris, being an open source version of what was to become Solaris 11, being a direct descendent of AT&T System V Release 4.0 UNIX.
What about OS/2 ?
I love that C came from Ken's wife Bonnie (B) and then morphed into C.
So how secure is Unix
I’ve heard that it’s more secure than windows due to popularity or rather lack thereof
Unix is not available in modern form, best to use Linux or BSD. But it is much more secure than windows because it uses file permissions and has privilege levels that are more granular than windows. And it actually requires a password to install things by default, that alone is what causes 80% of windows infections.
All online financial transactions are done in BSD due to that OS being much more secure.
I am here because of the original Jurassic Park movie from 1993.

Unix is a filesystem that spread and got out of hand.
Interesting take
It's your phone's people
Why is UNIX important?
Because of Jurrasic Park.
It's a UNIX System!!!
Absolutely
There's only one linux operating system that is certified as Unix. Only one. It's a Chinese Linux.
If anyone has used a MacIntosh that runs macOS, then he/she most definitely has USED Unix, because macOS is a Unix operating system.
I always understood that Linux came from MINIX, not UNIX.
But minix came from Unix
