What is Unix and why does it matter? Operating System OS Explained, History, Unix vs Linux, etc.

What about OS/2 ?

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.

If anyone has used a MacIntosh that runs macOS, then he/she most definitely has USED Unix, because macOS is a Unix operating system.

Well, the graphic artist took the labels off the legends!!!

Duh. Green means Unix-like, but the narrator didn't tell his audience so.

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.

Any Linux can be Unix if it becomes certified as such by The Open Group. One Linux is Unix. Only one.

There's only one linux operating system that is certified as Unix. Only one. It's a Chinese Linux.

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.

Unix = C
Microsoft Windows = C:
Linux = / 👈 slash or solidus symbol, very simple and great! 😎

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.

Pay some respect lol

I love that C came from Ken's wife Bonnie (B) and then morphed into C.

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!!

macOS is a certified Unix OS

Your narration sucks shit. But other than that, good vid

unix is the shit because of which we got GPL licence today .

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.

I always understood that Linux came from MINIX, not UNIX.

Great video, it really resumes very well how we evolved with Unix operating system.

That tree is fantastic!

Watch the computer cronicals episodes about Unix with garry Kildal who created Dos.

Just watched this video on a lightweight RISC Unix machine known as an iPad

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)

Great explanation. Thx

Simple, clear and straight forward!

It’s responsible for half of the phones on the planet, and the grand daddy of the other half.

RIP: Dennis Ritchie

Thank you, from Brooklyn.

explained it well

Great video, thank you so much!

Thanks 🙏

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<< like? When people were sitting in front of a computer with Unix as the OS, what were they looking at? GUI and whatnot...

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

So how secure is Unix

good explanation

Very helpful. thank you.

Thanks a lot brother

thank you for this video!

underatted video, deserves more views
