Unix was started by Ken Thompson, Dennis Ritchie and some other engineers including Brian Kernighan back in the early 1970s. It has a long and illustrious history. But then Linux came along and things changed. How is Linux different to Unix? Are they the same thing? Please, let me explain!Twitter: https://twitter.com/garyexplainsInstagram: https://www.instagram.com/garyexplains/
I have the same hat :D. I wonder you got that from some event or some employee.
I recall some of the early years when linux and x-windows started in the 90's.. It was much to raw for me at that time. So I think you for braking it all down and yes even this old dog learn something new today... wow ty
Thanks Gary. It was informative
Honestly, that was so boring.I just want to know the difference, the extra talks made me feel like if I'm attending a class or somethingYour channel is amazing btw
Linux is a kernel, 'GNU + Linux' is the operating system. This is a very important distinction, a similar analogy would be to call Freddy Mercury, Queen. He was part of Queen but not Queen itself. As to say linux is the kernel (the almighty arbitrator and frontman ) but pretty useless with out the GNU and Richard Stallman (how would you compile linux?).
holy shit dude i clicked you thinking you were unbox therapy, awkward. Well good thing i'm into linux i suppose :D as you were
You skipped a mile in the middle: The main Unix version in 1982 to 1990 was SunOS - a Unix 4.2 from SMCC. The events that proceeded OSF was the development in Europe of a standard for the Unix versions. This forced AT&T to publish the "System 5 Interface Definition". Minix is a spin-off completely irrelevant. The X/Open Foundation release the X/Open definition, and with SVID, Unix BSD could be released as the first SVID compliant. The IEEE developed with the Open Software Foundation (OSF) their definition, that replaced the US DoD Ironman and Steelman requirements. This where Linus Torvald entered the scene. He had the definition of how the OS should work in detail. He had the iAPX386 instruction set, and Motorola MK68K/ MK88K. Linux is written from scratch, and is a complete implementation done by Linus Torvald. The code he made, was accepted by the OSF and IEEE and found to comply to their specification for an operating system, Unix version 5, should also comply to this. To remove the last reference to Bell, the Bourne Shell was re-implemented in "bash" and was made available as open source. Unix was a protected trademake and name, all use of the name "Unix" was therefore licensed whether you used it for real or just made claims of use. AT&T was denied access to the computer market, because it controlled the long-haul telephony network in he USA, and some of us considered their power here as a threat to developing competitive computer-based technology. Unix was a name - like "Burger". Any software made, and claimed to be able to run on "Unix" paid a hefty commission to AT&T. Linux implemented the "SVID" on hardware, and is based on assumptions and trade-offs. Linus Torvald has the right to contest changes anyone makes in Linux regarding use of underlying hardware. He has made choices of technology not to use and what to use, and in an amazing way manage to stay on top of these issues. Bluntly, the main "opponent" to Multics is Nord TSS from Norsk Data, and their NORD line of products all on Sintran III. The F16 Flight simulator runs this OS. This is high end, high performance computers that was also sold as "minicomputers".
This channel deserves more subscribers.
Android is using Linux? Ummm, isn't almost everything some kind of Java JIT thing? "Using" as in the user uses Linux. Nah, it's a host. People wouldn't know they were using OS/9 if phone manufacturers wanted.
Commenting before I see the video! But I remember in the early 90's at a small university they had a (mid-late 80's minicomputer, well it's translated from Swedish and that is as I remember it was called "minidator") a setup with (as I remember it again) BSD Unix and a couple of really nice workstations (Sun?) 68020 equipped and it was really really fast and nice. Then we afterwards had a couple of 386's with Linux (can't remember the version but it was pretty much in the development phase from Linus himself mostly). And our teacher wanted a see how we would "react" to these different but somewhat similar OS'es. And it was pretty fun to have the "minicomputer" with workstations (which was so fast) and compare it to the "new" Linux with actually worked pretty good on "PC's" Although most of what made Unix so good was not even implemented of finished on Linux at the time you could see that it was getting there. Unix by that time was OS "god", as networking was at it's core.Edit, the multitasking (and reentrant code, without an MMU) was not news to me at the time as I was coding on AmigaOS. So that part was not that mindblowing for me.
Linux is a kernel, GNU/Linux is a OS 😎👍
very informative. Thank you!
Excellent history lesson. Thank you!
Great video, been a Linux user for 20 years and enjoyed the history lesson.
The top 500 fastest supercomputers today now almost all run Linux. I recall reading one Unix left.
I'm here to say that um GNU/Linux yeah kernel not OS and GNU > Linux. SO in case you didn't realise GNU and yeah not Linux.Stop. Everyone knows. No one cares. It's called Linux.
In the 80's I worked on a inventory program written in C and could be compiled to run either on MS-Dos or SCO Xenix systems, initially 286 Cpu's with multiple VT100 compatible terminals. I found the whole Unix/Xenix/Linux thing confusing and I really appreciate you helping to clear this up.
I personally prefer linux to unix.
Linux saved my life back in the 1990s. Never looked back.
Nice video.. solid information. Thank you
