I am doing my bachelor's degree at a university. In a written assignment, the professor posted the task: 'Name three PC operating systems'.
https://forwardtree592.weebly.com/blog/download-anime-movies-english-subbed. Well, I went on an included a variety of OSes (Linux, Windows, Mac OS X) and including Unix & Solaris. Today I received a mail from my professor saying:
Unix operating system free download - Operating System, The LoseThos Operating System, SAT Operating System For TI-89, and many more programs. Results 1 - 20 - License: Free; OS: Linux Mac OS X Dos Unix Mobile Windows 2000 Windows. Ubuntu 64 bits is an operating system for laptops and computers.
Unix is not a PC operating system. Many Unix-variants are not PC-hardware compatible (like AIX & HP-UX. About Solaris: there was one PC-compatible version..)
I am kind of suprised: Even if many Unix-variants are PowerPC based and have a different bit-order – Those don't stop being PCs now, right?
The question was given in a written assignment! It was not a question that came up during the lecture!
Due to the original task being in German, I'll include it just to make sure nobody suspects an error in the translation.
Frage: Nennen Sie 3 PC-Betriebssysteme.
Antwort: Unix ist kein PC-Betriebssystem, viele Unix-Varianten sind nicht auf PC-Hardware lauffähig (AIX, HP-UX). Von Solaris gab es mal eine PC-Variante.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

Without a hard definition of what a 'PC' is, your assignment question is a lake of ambiguity. I used an AT&T 3B1 no later than 1987, which unequivocally ran UNIX and was marketed as a 'UNIX PC'.
Kyle JonesKyle Jones
It would depend on your definition of 'PC operating system' and subsequently on your definition of a personal computer itself. If the first refers to operating systems that run only on personal computers, you might as well rule out every imaginable one, including Windows, which also runs on mobile phones, PDAs, server machines, supercomputers and a bunch of other non-PC machinery. To my knowledge, there are no operating systems meeting this strict criterium, as part of the PC's definition may be in its use. An OS will or will not support a machine regardless of that.
Even a more objective, hardware-only classification will fail. There is no unambiguous set of PC hardware. You will need a more specific term, such as 'x86-64 architecture', but those are not necessarily the same. For instance, your professor's example of AIX not being compatible with PC hardware is false. AIX supports the PowerPC platform which is uncommon, but perfectly usable in PCs.
Any answer to a question as vague as 'name three PC operating systems' can be shot down.

I have two explanations for this:
- The task was supposed to name three PC-only operating systems
- Strictly put,
Unix
is not exactly an operation system - it's a family of operation systems, derived from the first one developed in 1969, and is not a PC operating System.

If your professor is one who simply makes up his own definitions (or one who doesn't believe in Wikipedia being the ultimate source of truth), you're basically at his/her mercy.
Otherwise, point him/her to these Wikipedia entries (or possibly their German counterparts):
A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end-user with no intervening computer operator.
An operating system (OS) is a set of programs that manage computer hardware resources and provide common services for application software.
Unix (officially trademarked as UNIX, sometimes also written as Unix) is a multitasking, multi-user computer operating system [..].
If you both agree to the assumption that Wikipedia can be believed, then Unix is definitely an OS for PCs.
Amos M. CarpenterAmos M. Carpenter
Your professor may have a different definition of a 'PC' than you - which is not to say he is correct. Originally, PC simply meant 'Personal Computer', and did not have any specific architecture. But his use of 'PC Hardware' sounds like he is using a different definition that only includes IBM Intel-based PCs.
When IBM came out with their PC, they simply called it the IBM PC, and people began using PC to mean IBM PC. So 'PC Compatible' was commonly used to mean IBM PC Compatible, as if IBM invented the personal computer, rather than just 'legitimizing' it. I personally think your professor is either being unclear and unfair, or completely wrong (or both).
This was a Unix PC: AT&T Unix PC, and ran genuine AT&T Unix.
That said, I wouldn't really call Unix a PC operating system today; even though it can be, it's pretty rare.
Edit: There is also the possibility - which can only be deduced after his comments - that he meant ones that are designed only for a PC, such as MS-DOS, DR-DOS, PC-DOS, and the original Mac OS (and possibly OSX).
Marty FriedMarty Fried
The 'About Solaris: there was one PC-compatible version' statement is incorrect. From 1992 to 2011, there has been ten Solaris versions supporting x86 hardware (2.1, 2.4, 2.5, 2.5.1, 2.6, 7, 8, 9, 10 and 11), not to mention the various OpenSolaris/illumos based ones.
In any case, since its early design stage, Unix has been developed with portability in mind so is not, unlike most if not all competing OSes of that time, tied to a specific architecture.
jlliagrejlliagre
First of all, I would not waste my time on people who think that 'name three PC operating systems' is an interesting homework exercise. Or even something to talk about.
Your prof moves his definitions around to try to make perfectly rational, right thinking people around him appear to be wrong.
Oh, I meant 'operating systems that exclusively have run on PC hardware'.
PC compatible? No, no! I meant IBM PC! Not HP, not Compaq, not ACER, not your ASUS motherboard from Taiwan in a no-name brand case.
Did I say PC/AT? No, I mean PC! You know, 4.77 Mhz, 512 K memory, floppy drives only. No Not the XT with its 10 meg hard drive, not the AT, and not the PCjr. No 80x86 where x is not blank, and the 86 isn't 88.
Acceptable answers might be: PC-DOS, MS-DOS 2.0, CP/M 86 and MS-DOS 3.3.

Mac OS X is Unix and the Leopard version is the first and only BSD variant to achieve Unix Certification, and that's certainly considered a PC operating system.
The various BSD variants are notable in that they are in fact descendants of UNIX, developed by the University of California at Berkeley with UNIX source code from Bell Labs. However, the BSD code base has evolved since then, replacing all of the AT&T code. Since the BSD variants are not certified as compliant with the Single UNIX Specification (except for Mac OS X 10.5 Leopard and Mac OS X 10.6 Snow Leopard), they are referred to as 'UNIX-like'.
So if your professor means UNIX as in the certified, branded version, that narrows the group considerably. If he means UNIX-like, that is a completely different semantic and opens the doors for way more things that run on PC hardware.
WyzardWyzard
Let's take an average definition of 'PC' being what the professor thinks it is -- an Intel desktop.
So he's trying to point out that Unix is a whole class of operating systems, many do not run on PCs.. This is correct.
![Original Unix Operating System Download Original Unix Operating System Download](/uploads/1/3/3/8/133864253/434736156.jpg)
However, Windows is also a class of operating systems, and wow.. many don't run on PCs!! Windows CE is a version of Windows, as are Windows Embedded and Windows Phone (with multiple versions).
Many versions of Linux don't run on PCs.
So the only 'correct' way to answer his question would be to list instances--something along the lines of 'Windows XP, Windows NT, Windows 7 and Windows 8' which is lame and he probably would have said something about these all being the same OS.
Linux is also a problematic answer, not all Linux builds are meant for PCs, although you could easily list 20 versions of Ubuntu made for PCs.
Mostly, the question should be, why do you have such a pointless and ambiguous question on your tests?

Is Unix a PC Operating system?
There were certainly (commercial) ports of Unix before Linux ever arrived on the PC scene, such as Interactive Unix and Santa Cruz Operations (aka SCO) Unix, that first ran on i386 and i486 PCs.
sawdustsawdust
First, I quote two lines from Wikipedia about Unix. This will make it clear the differences between Unix and UNIX.
Unix (officially trademarked as UNIX, sometimes also written as Unix) is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna.
The term Unix (capital U) is often used informally to denote any operating system that closely resembles the trademarked system.
Your professor is not wrong. When UNIX was created computers were so expensive that no one had a personal version. People usually used to share a Unix system which was running on a mainframe or minicomputer. Before UNIX became cheap, the IBM PC was released and many people could afford to buy it. And the term PC (personal computer) was broadened. After that UNIX or Unix became cheap and people could use them in PC (this PC is a common noun, IBM-PC is a proper noun).
Shiplu MokaddimShiplu Mokaddim
Maybe it is not a technical question but a political one.
Microsoft want us to believe that all other operating systems are old/slow/command-line only/hard to use/not used by anyone/…. I think that Microsoft has got to your professor.
This answer was sent from my Unix PC (Debian Gnu/Linux). Linux was originally an x86-only operating system. According to the owners of UNIX™ GNU/Linux is a Unix, but not a UNIX™.

Frage: Nennen Sie 3 PC-Betriebssysteme.
i'd guess PC in German is Einzelplatzrechner thus a single seat computer maybe
you might focus that computer cannot provide two seats but one - most MIDs with some embedded OS would be fine for today. Even windows is too functional in this regard.
or you want to thin PC is an IBM Personal Computer or similar.
Then you can name any system imaginable. OSX. Windows 95, FreeDOS (yes -apple systems can run windows also in place of OSX, just a bit costly)

Unix Vs Linux: Learn what is the Core Difference between UNIX and Linux Architecture, Kernel And Commands
Linux is nothing but a UNIX clone which is written Linus Torvalds from scratch with the help of some hackers across the globe.
Unix and Unix-like operating systems are a family of computer operating systems that derive from the original Unix System from Bell Labs which can be traced back to 1965.
Linux is the most popular variant and there comes in a number of different distributions.
Unix is a family of multi-tasking, portable, multi-user computer operating systems, which also have time-sharing configurations.
Unix systems use a centralized OS kernel which is responsible for managing the entire system.
The programming interface, file abstraction, built-in networking and persistent background processing called daemons are the other features and capabilities that are supported by a Unix OS. Ethernet controller driver windows 7 64 bit mega.
What You Will Learn:

What is UNIX?
Unix is considered as the mother of most of the operating systems.
The design of Unix systems is based on “Unix Philosophy” which includes the following characteristics:
- Usage of plain text for data storage.
- Hierarchical file system.
- Handling devices and some specific kinds of inter-process communication (IPC) as files.
- Employing a huge number of software tools.
- Multiple small, simple and modular programs which can be threaded together via a command-line interpreter using pipes, contrasting to use a single monolithic program which comprises of all the same functionality.
It’s worth mentioning here the below quote about Unix Philosophy:
“Although that philosophy can’t be written down in a single sentence, as its heart is the idea that the power of a system comes more from the relationships among programs than from the programs themselves. Many UNIX programs do quite trivial things in isolation, but, combined with other programs, become general and useful tools.” – Brian Kernighan & Rob Pike
Unix Architecture
The below diagram will depict you the Unix architecture.
[image source]
The master control program of Unix is its Kernel. The kernel has full control over the entire system. It has subsystems that offer services to file system handling, resource handling, memory management, start & stop programs and few other low-level core tasks.
The kernel is the heart of the OS and acts as an interface between the user and hardware. Each kernel subsystem has certain features like concurrency, virtual memory, paging, and a virtual file system.
In the outer layers of the architecture, we have the shell, commands and application programs. Shell is the interface between the user and the kernel. Shell and the user types in the commands, interpret these commands and call the computer programs accordingly.
Example of the Unix operating system is Solaris and HP-UX. The largest distributors of UNIX systems include IBM, HP, and SUN.

What is Linux?
By now you would have got a fair idea about Unix. Let's now explore Linux in detail.
People do confuse a lot between the terms Unix and Linux and they generally ask questions like “Is Unix Different from Linux?” / “Are Linux and Unix the same thing?” / “Is Linux like Unix?”/ “Is Linux built on Unix?”.
Here is the answer to all such questions. First, let me clear your confusion in a one-liner. Linux and Unix are different but they do have a relationship with each other as Linux is derived from Unix.
Linux is not Unix, but it is a Unix-like operating system. Linux system is derived from Unix and it is a continuation of the basis of Unix design. Linux distributions are the most famous and healthiest example of the direct Unix derivatives. BSD (Berkley Software Distribution) is also an example of a Unix derivative.
Freakonomics pdf free ebook download. At this juncture, it is important for us to make you clear about what is Unix-like?
A Unix-like OS (also called as UN*X or *nix) is the one that works in a way similar to Unix systems, however, it is not necessary that they conform to Single UNIX Specification (SUS) or similar POSIX (Portable Operating System Interface) standard.
SUS is a standard which is required to be met for any OS to qualify for using ‘UNIX’ trademark. This trademark is granted by ‘The Open Group’.
Few Examples of currently registered UNIX systems include macOS, Solaris, and AIX. If we consider the POSIX system, then Linux can be regarded as Unix-like OS.
As per Linux kernel official README file, Linux is a UNIX clone that is developed from scratch by Linus Torvalds and team. It targets for POSIX compliance. The Linux kernel code was completely written from scratch. It is designed in such a way so that it acts like Unix but it does not have the original Unix code in it.
It is also significant to note that Linux is just the kernel and not the complete OS. This Linux kernel is generally packaged in Linux distributions which thereby makes it a complete OS.
Thus, Linux is only the Kernel, while Linux distributions can be treated as the OS. On the other hand, UNIX in itself is a complete OS as everything (all required application tied together) comes from a single vendor. For Example,Solaris.
Linux distribution (also called as a distro in short) is an operating system that is created from a collection of software built upon the Linux Kernel and is a package management system.
A standard Linux distribution consists of a Linux kernel, GNU system, GNU utilities, libraries, compiler, additional software, documentation, a window system, window manager and a desktop environment.
Most of the software included in Linux distribution is free and open source. They may include some proprietary software like binary blobs which is essential for a few device drivers.
Linux based OS Architecture
[image source]
Thus, Linux distributions actually make the Linux kernel completely usable as an operating system by adding different applications to it. There are various flavors of Linux distributions that serve a wide range of user needs.
For Example, we have OpenWrt Linux based OS for embedded devices, Linux Mint for Personal computers and Rocks Cluster Distribution for supercomputers. In total, around 600 Linux distributions do exist.
It will be interesting for you to know that Google’s popular Android mobile OS is based on Linux. Every iteration of the Android OS is built on the current Linux kernel.

We hope you must have understood the core differences between Unix and Linux from this article.
Let us now see some more important differences between Linux and Unix in the below tabular format:
Features | Linux | Unix |
---|---|---|
Developer | Inspired by MINIX (a Unix-like OS), Linux was originally developed by Finnish-American software engineer Linus Torvalds. Since it is an open source, we have community developers for Linux. | Originally derived from AT&T Unix, it was developed at Bell Labs by Kenneth Lane Thompson, Dennis Ritchie, and 3 others. |
Written in | C and other programming languages. | C and assembly language. |
OS family | Unix-like | Unix |
Working state | Current | Current |
Source Model | Open source | Mixed. Traditionally closed source, however, few Unix projects are open source which include illumos OS and BSD (Berkley Software Distribution) OS. |
Available in | Multilingual | English |
Initial release | Linux is newer when compared to Unix. It was derived from Unix and was released in September 1991. | Unix is older. Was released in October 1973 for outside parties. Before that, it was used internally in Bell Labs since its inception in 1970. |
Kernel Type | Monolithic kernel | Kernel Type varies. It can be monolithic, microkernel and hybrid. |
License | GNUv2(GPL General Public License) and others. | Licensing varies. Few versions are proprietary while others are free/OSS. |
Official Website | https://www.kernel.org/ | http://opengroup.org/unix |
Default user interface | Unix shell | CLI (Command Line Interface) and Graphical (X Windows system) |
Text Mode Interface | By default, the shell is BASH (Bourne Again Shell). Moreover, is compatible with many command interpreters. | Originally the Bourne shell. It is also compatible with many command interpreters. |
Cost | Can be obtained and used freely. There are priced versions of Linux as well. But, generally, Linux is cheaper than Windows. | Proprietary operating systems have different cost structures set accordingly by the vendors selling it. |
Examples | Debian, Ubuntu, Fedora, Red Hat, Android, etc. | IBM AIX, Solaris, HP-UX, Darwin, macOS X, etc. |
Architecture | Was originally created for Intel's x86 hardware, ports available for a lot of CPU types. | Compatible with PA and Itanium machines. Solaris is also available on x86/x64. OSX is PowerPC. |
Threat detection and solution | As Linux is mainly driven by open source community, many developers across different parts of the world are working on the code. Hence threat detection and solution is quite fast in case of Linux. | Due to the proprietary nature of Unix, users need to wait for proper bug fixing patches. |
Security | Both Linux and Unix based OS is generally regarded as very well protected against malware. This is attributable to lack of root access, quick updates and comparatively low market share (as compared to windows). As of 2018, there has been none widespread Linux virus. | Unix is also considered to be very safe. It is even harder to infect as the source is also not available. There is no actively spreading virus for Unix nowadays. |
Price | Linux is free. However, corporate support is available at a price. | Unix is not free. However, some Unix versions are free for development use (Solaris). In a collaborative environment, Unix costs $1,407 per user and Linux costs $256 per user. Hence, UNIX is extremely expensive. |
Linux vs Unix Kernel
As Linux alone is just a kernel, it is worth discussing the major differences between the Linux Kernel and Unix kernel.
There are three types of the kernel i.e. monolithic, micro and hybrid (combination of monolithic and micro) as seen in the below image.
[image source]
In monolithic kernel architecture, the entire OS works in single kernel space. It single-handedly defines a high-level virtual interface on top of the computer hardware.
Though Linux kernel derives most of its characteristics from Unix/ Unix-like kernels, however, there are some significant points of differences between the two.
In microkernel architecture, the core services of the OS run in one process while the other services run in different processes.
In µ kernel, the near-minimum amount of mechanisms is included in the kernel mode. These mechanisms include basic IPC (inter-process communication), scheduling and low-level address space management.
In terms of source code size, generally, a microkernel is smaller than the monolithic kernel.
Features | Linux Kernel | Unix Kernel |
---|---|---|
Kernel approach | Linux follows the monolithic kernel approach. | Unix kernel can be monolithic, microkernel or hybrid. For Example, macOS has a hybrid kernel, Solaris has the monolithic kernel, and AIX has a monolithic kernel with dynamically loadable modules. |
Adding/removing features of the kernel | Provides a great feature through which the kernel components like device drives can be dynamically added and removed as modules. This feature is called as loadable kernel modules (LDM). This eliminates the need to compile the whole kernel again. This feature in turn gives great flexibility to Linux. | Traditional Unix systems kernel need static linking of new systems being added. |
Streams | In Linux, there are no streams I/O subsystem. | In most of the Unix kernels, streams I/O subsystem is included which turns out to be the desired interface for writing device drivers, terminal drivers, etc. |
Preemptive vs non-preemptive approach | Normally a Linux kernel is non-preemptive. However, in recent times, Linux real-time OS has started using preemptive kernels. | Some Unix systems are fully preemptive. For example, Solaris 2.x. etc. |
Kernel threading | Linux uses kernel thread just for running some kernel code periodically. | Many Unix-like operating systems use kernel thread for the purpose of process context switching. |
Ways to handle the multi-threaded environment | Through multi-threading, more than one independent execution flows which are called lightweight processes (LWP) are created. In Linux, LWP is created by calling clone () function. These processes in Linux can share physical memory, opened files, address space, etc. | In Unix, the LWP is based on kernel threads. |
Unix Vs Linux Commands
There are certain differences between the shell commands i.e. even among the versions of the same Unix variant. However, what varies most is the internal shell that is built-in rather than the presentation.
On the whole, efforts are made to keep Linux as close as possible to Unix by complying with the POSIX standards. Hence, the terminal commands in Linux distros and Unix operating systems are not exactly the same, but, there are not many differences too.
Original Unix Operating System Download Software
Each Linux distribution in itself has its own way of execution.
For Example, in CentOS which is a Linux family OS, we use yum (yellowdog update modifier) commands for installation of new packages, while in Debian which is another OS from the Linux family, we use apt-get commands for installation.
In IBM AIX, which is a proprietary Unix OS, we use -finger command to check who is logged into the system. But this command is not used in Linux. In Linux, we use the pinky command to fetch the same result.
In Ubuntu/Debian (a Linux OS), we have fdisk, parted, gparted Cant download torrent from skidrow. commands for the ‘create’ task. On the other hand, in Solaris (a Unix OS), we have a format, fmthard for the ‘create’ task.
You can refer to the list of Linux and Unix commands, you will find that the Linux and Unix commands are similar but not exactly the same.
Examples
So far, in this article, we have seen the generalized core differences between Linux and Unix. These differences can be more specific if we compare the exact versions of the two. Let us see this through some examples.
Solaris vs Linux
Solaris, which is now called Oracle Solaris is a Unix family OS. Let's compare Linux with Solaris.
Linux supports more system architectures than Solaris does. Hence, Linux is more portable.
While talking about stability and hardware integration, Solaris seems to better here. Linux also has a faster rate of development when compared to Solaris.
There are few other technical differences between the two, but here we are limiting our comparison only to performance.
MacOS vs Linux
MacOS is a certified Unix OS. It has its own kernel named XNU. It is used in Apple’s computers which are considered as the most reliable PCs.
MacOS is relatively easy to set up. On the other side, Linux is cheaper and has a lot of open source software available as against Apple’s proprietary solutions. Also, Linux is more flexible as it can be executed on almost any hardware whereas MacOS can run only on Apple hardware. For Example, iPhones.
MacOS uses HFS+ as a default file system whereas Linux uses ext4.
Conclusion
Unix is very old and is said to be the mother of all operating systems. Linux kernel is also derived from Unix. The major difference between Unix and Linux based operating systems is not in the presentation part, but on how they work internally, i.e. mainly at the kernel part.
The difference between the two will also depend upon which exact versions of Linux and Unix you are comparing.
It’s also essential to state that Linux (and many other Unix-like OS) are free to obtain and modify, whereas Unix operating systems are not. Cost is always a major concern while deciding what technology to use, and Linux has an edge in this regard.
Linux is more flexible and free when compared to true Unix systems and that is why Linux has gained more popularity. While discussing the commands in Unix and Linux, they are not the same but are very much similar. In fact, the commands in each distribution of the same family OS also varies.
Solaris, HP, Intel, etc. employ Unix internet servers, workstations, and personal computer. While, Linux is widely employed for computer software & hardware, gaming, tablet, mainframes, etc.
There are studies which say that Linux is growing fast than any other OS in the past few years. Hence, in the future, Linux may tend to leave UNIX installations far behind.
