Talk:Operating system/Archive 5

Although I can see why it is tempting to reorder the examples of OS's to suit our view (or the view of the market), the market and our cultural view changes over time. In this case another editor will want to swap the list around to suit and then another and another. To see examples of this behaviour we need only look at the article history. I set the list in alphabetical order some time ago (and at the time added a note hinting as to why). I strongly suggest that the article features lists that will be reordered (time and time again for various and often pointless reasons) to be ordered alphabetically and left that way. fg^t_c 21:26, 5 November 2011 (UTC)

• I was the editor who recently changed the order to reflect market share. I did it because I saw another re-ordering get reverted and thought "oh, the ordering seems to be chosen at random, so I'll order it in a less arbitrary way." If you prefer to order it alphabetically, I have no specific objection, so please proceed. SocratesJedi | Talk 03:09, 9 November 2011 (UTC)

No particular order matters which is actually the problem. Everyone has their own view of which way around they should be so the order gets shifted around for all kinds of reasons (I think typically it comes down to favouritism). The only order that has no connotations seems to me to be alphanumerical. Unless we are enslaved and indoctrinated by 12 fingered telepathic aliens, I think there is little chance the order will get out of date. I added a note a while back reading that the list was not exhaustive and was alphabetical in order to try to avoid this constant flux but the note was thought to be un-encyclopaedic. Alphabetical or alphanumerical lists are however very encyclopaedic so I really think that would be best. Thanks for your input. fg^t_c 03:28, 9 November 2011 (UTC)

I'm not much of an author so I will leave editing the article to a better writer with more details. This article misses not just an operating system but a class of computers. 'Mini computers' include IBM's AS400 which can run several operatng systems including OS400, and HPs HP3000 using the MPE operating system. (I was an HP3000 system operator.) Introduced sometime in the 1970's, HP stopped making the HP3000 in 2002 and stopped supporting it in 2004. I think that the MPE operating system is now owned by OpenMPE. — Preceding unsigned comment added by 4.254.228.86 (talk) 14:33, 15 May 2012 (UTC)

I do not think that the IP’s addition is something really “out of place”, so not only this Wtshymanski’s edit constitutes a biting of a newcomer, but his edit summary deceives Wikipedia users about the true nature of that reverted addition. Opinions? Incnis Mrsi (talk) 06:43, 8 April 2013 (UTC)

Normally I would assume good faith, but given Wtshymanski's long history of deliberately making "mistakes" in order to remove content (look at how many times has he proposed a speedy deletion for a reason not on the list of criteria for speedy deletion), I must conclude that he knew perfectly well that the top part of his edit "moved" a reference without changing what is displayed on the page and that the edit comment was a deliberate attempt to deceive the reader into missing the content removal below.

Linux is just the kernel of several operating systems. Operating systems provide the interface between applications and the hardware device handling program. The kernel handles the hardware devices. The operating systems that use the kernel Linux are GNU, BSD, Unix and others. So the article should replace the term "Linux" with "GNU, Unix and BSD". Quiliro (talk) 22:17, 20 December 2011 (UTC)

Too much water under that bridge to turn back now. Even if strictly correct, "Linux" is known to be an operating system. fredgandt 00:00, 21 December 2011 (UTC)

We don't entertain the GNU/Linux naming controversy here. The Wikipedia manual of style specifies that we use the most commonly used names for things. Thus the article about Linux is titled Linux, not GNU/Linux and there is a separate article on the Linux kernel. (As a caution, editors who edit war over this generally earn blocks for violating this policy.) Yworo (talk) 00:06, 21 December 2011 (UTC)

Technically Linux kernel is the operating system, and it is not wrong to call Linux kernel only as Linux because it is its name after all. It is just plain wrong to call anything else than Linux kernel (bundle of different software) as Linux. And Linux is not used by any other OS because it is technically impossible. Linux is a monolithic operating system, like original Unix and BSD's are. While HURD is server-client operating system. Golftheman (talk) 08:43, 26 April 2012 (UTC)

Linux Kernel is mentioned without reference to Linus Torvalds. Several other names are cited in the article. The strategy that Linus used to develop, improve, and register changes to the official kernel, namely the internet, is noteworthy as it used the world wide web "system of operating systems" to foster a new UNIX like OS.

someone should point out that real-time operating systems are defined to be operating systems with exactly known wall-clock response time. that is, they respond to specific requests in specific amounts of time, like 2 seconds. — Preceding unsigned comment added by 173.228.28.61 (talk) 18:24, 17 May 2014 (UTC)

Under the 'Types of operating systems' section in the 'Real-time' paragraph the writer starts to talk about event driven vs time shared systems. I fail to see how these design notions are specific for real time operating systems. I would agree that in a real time OS these things require a closer look, but the concepts are so universal that they are wider (and older) than the concept of the OS itself. — Preceding unsigned comment added by 83.87.238.229 (talk) 17:45, 29 January 2013 (UTC)

"An operating system (OS) is a collection of software". Oric-1 (my old computer) links here, and similar ZX Spectrum lists Sinclair BASIC as an operating system.. These and similar old computers had what I would not consider operating systems (in the modern sense) or what..? [And DOS..] Why am I bringing this up. They certainly are system software. They act as a shell and provide a user interface and I consider that a part of an OS. Their ROMS are a collection of software routines, but are they one software, not a collection? A kernel on it's own (such as the Linux kernel) is not a full OS or would you disagree? "Linux" with a shell (and/or only GUI) is. Mac OS (older versions) are also not an operating system without their UI.

System software: "The operating system (prominent examples being z/OS, Microsoft Windows, Mac OS X and Linux), allows the parts of a computer to work together by performing tasks like transferring data between memory and disks or rendering output onto a display device. It also provides a platform to run high-level system software and application software." [.. and then a separate example..] "A user interface". UI is system software, is it being treated as separate from the OS? comp.arch (talk) 15:28, 22 May 2014 (UTC)

The definition of an operating system is included, the contradicted with examples that are do not perform those functions. Microsoft Windows does not manage hardware resources and give software the ability to use a diverse number of hardware components through common interfaces. The NT kernel (I would tend to argue operating system) does.

This aspect of the article should be evaluated. — Preceding unsigned comment added by 75.170.136.2 (talk) 18:44, 30 May 2015 (UTC)

"The operating system is an essential component of the system software in a computer system."

No it isn`t. It is perfectly possible to run a computer system without an operating system and in times past this was frequent, if not normal, practice in small systems. All that is essential is either a pre-loaded application or OS, or some form of bootstrap loading mechanism. In the modern world even embedded processors tend to have operating systems - after all it makes it all much easier. But that doesn`t make it essential. Bagunceiro (talk) 22:58, 10 July 2015 (UTC)

What does this sentence from the article actually mean? 70.247.167.104 (talk) 06:03, 19 February 2014 (UTC)

All methods require some level of hardware support, which doesn't exist in all computers.

What we're trying to get at is that -- no matter which method of memory protection an operating-system programmer chooses when writing an operating system -- there will be some computers out there that can't run that operating system because they don't have the necessary hardware to support that particular method of memory protection.

There are lots of different techniques that an operating system can implement memory protection.

Each specific technique requires a specific kind of hardware support -- for example, paging requires a paging memory management unit. For example, memory segmentation requires segment registers. For example, efficient hardware virtualization can be implemented on hardware that supports the Popek and Goldberg virtualization requirements.

The entire point of the μClinux operating system is to support the many computers do not include a MMU, and so they cannot run standard Linux which uses a memory protection system that requires a paging MMU.

If you choose any one of those 3 techniques, there are lots of computers that don't have the hardware support for it -- even though they may have hardware support for one or more other techniques.

Is there some way of clarifying that section of the article without going into so much detail?

New to wikipedia talk section so excuse any protocol breaks I make, but SteamOS is definitely based on Linux, so the header section really shouldn't list it as a separate UNIX based OS. — Preceding unsigned comment added by 18.189.70.27 (talk) 16:15, 4 December 2015 (UTC)

I've put SteamOS inside the parenthesis after Linux, and near Debian, with which it's associated. The OS isn't mentioned later on, so we've got more detail in the lead than in the body, which shouldn't be the case. Dhtwiki (talk) 23:26, 4 December 2015 (UTC)

There`s far too much in the list in the lead. We don`t need to list every existing OS as an "example of [a] popular modern operating system". I think we should restrict it at this level to Windows, Linux distros (without listing them), Android and OS/X. Further explanation and expansion to follow in the body. Bagunceiro (talk) 00:24, 5 December 2015 (UTC)

In the fourth alinea it states that the first seven of above mentioned operating systems are unix based, with the recent edit of putting steamOS under the linux category this makes it now the first six. JJK96 (talk) 21:49, 10 December 2015 (UTC)

I've made the change. Thanks for pointing that out. Dhtwiki (talk) 08:59, 11 December 2015 (UTC)

The article claims that the first PC to run Windows was the PS/2. However, this was launched in 1987, two years after the first release of Windows. Suggest this needs clarifying or scrapping. Bagunceiro (talk) 16:12, 19 December 2015 (UTC)

Maybe someone was thinking of OS/2. That sentence can be scrapped. It would be hard to determine the first computer to "run" any operating system. Also the article says "Microsoft Windows originated in 1985...", which is probably better put as "first released in 1985". Dhtwiki (talk) 11:19, 20 December 2015 (UTC)

I want to simplify the last paragraph in the lead but I`m not entirely sure what to do. As it stands it is inaccurate and selective, but not selective enough - worse than useless I think. My preference is simply to delete it; I don`t think it adds anything to the article and left there it is an open invitation for everyone to add their own preferred OS and it just grows out of all proportion as it is now. The alternative might be to place a strict limit on it - something like "Examples of popular modern operating systems include Microsoft Windows, Apple OS/X and Linux variants including Android" would do as what I suppose it is trying to do is make clear what is meant by an OS. However, without some agreement here neither of these would hold. Does anyone have any views on this matter? Any other proposal? Bagunceiro (talk) 23:19, 10 December 2015 (UTC)

I'd think about moving some of the detail further down, rather than just deleting. It might be of some use to place some of the more popular offshoots with their parent OSs. I don't like peremptory deletions, unless the material is of absolutely no value. Someone wanted to see that information placed, although I agree that mere laundry lists of OSs can grow and be hard to maintain. Dhtwiki (talk) 09:04, 11 December 2015 (UTC)

I´d agree with the principle of that, except that I think it is already there. Bagunceiro (talk) 11:32, 11 December 2015 (UTC)

I thought that wasn't the case, but see that it is. So, simplifying the lead, as you suggest, especially reducing the too-long parenthetical after Linux, is OK, without worrying about losing information (I'd not heard of SteamOS before). Dhtwiki (talk) 17:51, 11 December 2015 (UTC)

OK, well with the lack of further input I'm going to make the change. Bagunceiro (talk) 11:49, 16 December 2015 (UTC)

Yes, I put real-time operating system (RTOS) in the list. They are also operating systems, and the article should reflect that, and I think recognize the most popular ones, even if the general public doesn't know them. Taking them out, that are more popular than say OS X (while leaving that in), seems biased to me. comp.arch (talk) 11:44, 4 February 2016 (UTC)

It doesn't claim this list is exhaustive or even "popular" any more. It's just a short list of examples which a typical reader may have heard of.

Actually I'd like to remove the list altogether - I don't think it achieves anything except to generate controversy since people get upset that their own favourite is missing. Suggest we delete this and leave it to the examples section (and add RTOSs, for example, to that). Bagunceiro (talk) 12:13, 4 February 2016 (UTC)

Maybe I can live with you just dropping the list. At the time I just added the most popular RTOSes. The list was already there. I'm not sure it helps to list OSes in an example section, then you might just get controversy there.. [and the lead should summarize it/articles]. The list I left in included only popular (I expect you had issue with z/OS, that is most popular in its category if you define them narrowly, maybe it's not "modern" however..). It seems strange to list no examples [in the lead].. but then again Car doesn't.. Programming languages, name C and Perl. I'm ok with that. At least C. comp.arch (talk) 13:22, 4 February 2016 (UTC)

I don't have any quarrel with any of them per se. What I object to is a long and complicated sentence which just boils down to a list of names for people to fight over - it adds nothing. Bagunceiro (talk) 17:06, 4 February 2016 (UTC)

Before I saw this discussion I re-added the short list of OSs as it existed on February 3, along with its accompanying hidden comment. I don't think that it hurts to exemplify in the lead the concept of an OS, using a short list of software people are likely to be acquainted with. The comment explains that the list isn't meant to be exhaustive. Dhtwiki (talk) 16:49, 5 February 2016 (UTC)

Agreed, provided it stays that way. We shall see. Bagunceiro (talk) 17:35, 5 February 2016 (UTC)

Is your question why equal attention isn't paid to Arabic, as to vision and hearing impairment, with regard to accessibility? In my experience, operating systems come with considerable "locale" facilities, to change the prompts, error messages, etc., to the language of one's choice. This might be better addressed at Arabic Wikipedia, in any case, although their OS talk page hasn't shown activity since 2008. Is that why you're asking here? Dhtwiki (talk) 21:53, 19 March 2016 (UTC)

I don't mean to be an "operating system chauvinist" but the History section seems to jump directly from mainframes to microcomputers, omitting minicomputer OSs, and particularly Unix, which most people would agree is a historically significant OS. The word "Unix" only occurs 4 times, in the context of the development of Linux. Chetvorno^TALK 17:22, 25 March 2016 (UTC)

I see that there is little to no discussion of minicomputers per se in the History section. However, there is plenty of discussion of Unix, and Unix-derived systems, in the Examples section, more than on any other operating system, "Unix" being mentioned more than four times, I would say. Dhtwiki (talk) 23:58, 25 March 2016 (UTC)

The statement on realtime OS that "A real-time operating system is an operating system that guarantees to process events or data within a certain short amount of time" is misleading. The realtime characteristic isn't so much about being fast as being predictable in its time characteristics and considering deadlines in its scheduling algorithm. Granted, realtime operating systems often are, in fact, very fast but speed alone isn't the defining characteristic. — Preceding unsigned comment added by Ejs1985 (talk • contribs) 16:56, 24 June 2016 (UTC)

Yes, I think it is. We could add links to Chromium OS and Chrome OS to the ever-growing list at the end of the Linux section. ~Kvng (talk) 04:36, 21 July 2017 (UTC)

I want to know that why firmware doesn't need os to function. — Preceding unsigned comment added by 39.42.55.174 (talk) 18:00, 4 December 2017 (UTC)

Because it's the other way around - The computer requires the firmware (by which we're talking about BIOS, UEFI etc.) to run the OS. In effect the OS sits "on top" of the firmware.

Having said that, the sentence you are referring to (All computer programs, excluding firmware, require an operating system to function.) is at best misleading. Only programs that are written to run in an OS environment require an OS. That is the vast majority, of course, but excludes much embedded and specialised code. Bagunceiro (talk) 19:37, 4 December 2017 (UTC)

I've removed the sentence. There are a great many examples through history of computers that had no operating system, yet they seemed to be able to run programs just fine. Jeh (talk) 19:47, 5 December 2017 (UTC)

I was trying to think of the best way to improve it, and I think you've found that! Thanks. Bagunceiro (talk) 20:06, 5 December 2017 (UTC)

Sure. Decommission Wikipedia and you don't need to improve it anymore.

Also, search the history and find all the examples you want. There are trillions of apps that need an operating system.

On the other hand, computer programs that don't need an OS are firmware, bare-metal hypervisors, bootloaders (well, a bootloader is always part of an OS) and bootkits.

FleetCommand (Speak your mind!) 21:22, 5 December 2017 (UTC)

Hyperbole much? Nobody is saying this is the last improvement that needs to be made. I'm used to much better from you than this, FC. Jeh (talk) 21:26, 5 December 2017 (UTC)

@Jeh: Really? Thanks. I take that as a complement. Nobody has ever said that he or she is used to "much better" from me. It is, however, safe to say that all application software and all mobile apps (which could either be application or utility, despite the word "app") need an OS. Supreme regards, FleetCommand (Speak your mind!) 21:32, 5 December 2017 (UTC)

I don't think it's safe to say that at all. But I guess it depends on what you mean by an OS. Is a simple loader, one that provides no services to the program after it's been loaded, and which must be started from scratch in order to load the next program, an "OS"? I don't think so. I've used and written a lot of "application software" that depended only on a loader that was more or less hardwired into the machine. Jeh (talk) 22:13, 5 December 2017 (UTC)

A simple loader is not an OS. But also, a computer program that does not require an OS is, by definition, neither application nor utility, bearing in mind that these two categories do not encompass all computer programs. But they do encompass all apps; because apps are either applications (mostly) or utility (rarely).

If what you make supervises hardware resources, then it is an OS. "Supervisor" is another name for operating system. FleetCommand (Speak your mind!) 09:49, 7 December 2017 (UTC)

"a computer program that does not require an OS is, by definition, neither application nor utility". I don't know how you can believe that, other than that your experience in the industry must not include older machines. There was no "operating system" on the very successful IBM 1401, for example, but a great many shops ran business applications (payroll, billing/receivables, banking,general accounting, inventory, student management, etc., etc.) on them, as well as development for all of the above, plus utilities (in particular tape-to-printer and card-to-tape, in service to e.g. a 7090) on it. No job monitor, no OS "supervising hardware resources", etc. (What "supervised hardware resources" was the operations staff. ;) ) Jeh (talk) 12:01, 7 December 2017 (UTC)

Please change "This is achieved by time-sharing, dividing the available processor time between multiple processes that are each interrupted repeatedly in time slices by a task-scheduling subsystem of the operating system." to "This is achieved by time-sharing, where the available processor time is divided between multiple processes. These processes are each interrupted repeatedly in time slices by a task-scheduling subsystem of the operating system." The original sentence is hard to read because of the length so I propose breaking it down into two.

Please change "Unix-like operating systems, e.g., Solaris, Linux, as well as AmigaOS support preemptive multitasking." to "Unix-like operating systems, such as Solaris, Linux, and AmigaOS, support preemptive multitasking."

An operating system/kernel manages the computer's resources and distributes them among the apps that need those resources.

Windows NT is an operating system, but it's not a kernel because windows nt's kernel can't work alone, as it's not monolithic.

Linux is a kernel and an operating system because Linux can work alone, because linux is a monolithic kernel.

Windows and Ubuntu are distributions (distros), as they are a ready to use environment, as they include an operating system and pre-installed apps, as well as a graphical user interface.

Problem is, there's only one Windows NT distro, windows, but there are hundreds of linux distros. so, should windows be called a distro or not?

What's the difference between kernel and operating system?

"An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs." "The kernel is a computer program that is the core of a computer's operating system.... The kernel's primary function is to mediate access to the computer's resources.... The kernel has full access to the system's memory and must allow processes to safely access this memory as they require it.... " btw take a look at the spanish language wikipedia articles for linux, sistema operativo, and microsoft windows. Pancho507 (talk) 05:06, 16 May 2019 (UTC)

What means “Linux can work alone” – without any user-space process? It could act as a network router, for example, but generally it is not used in this way. What means “windows nt's kernel can't work alone”? Surely the sole ntoskrnl.exe image is insufficient for anything, but the file contains only a part of Windows kernel. One has to load several files to obtain a viable NT kernel in the primary memory, but otherwise it functions no different from Linux in principle. There is a lot of confusion in the Pancho507’s posting above. Incnis Mrsi (talk) 12:31, 18 May 2019 (UTC)

The Linux subsection (section 3.2.1) should be on the same level as macOS or Microsoft Windows (i.e. should be section 3.3 in the current document structure). Linux does not evolve from MacOS and in fact predates it, so there is no justification for it being under its subsection. 153.98.68.196 (talk) 11:21, 18 June 2019 (UTC)

 Done Linux is Unix-Like, so I moved it to that section. RudolfRed (talk) 18:54, 18 June 2019 (UTC)

I've made some further adjustments, putting the macOS subsection ahead of the Linux one because the former began as NextStep OS in 1988, although not becoming the underpinnings of macOS until ten years later, while Linux started in 1991. Dhtwiki (talk) 10:44, 19 June 2019 (UTC)

Both Burroughs MCP (1961) and Unix (1973) are claimed to be the first operating system written in a high-level language. One or both of those claims should probably be qualified. It's certainly true that Unix portability owed much to being written in C, but MCP definitely predates Unix. Nukeqler (talk) 15:55, 8 November 2019 (UTC)

Change "Interrupts are central to operating systems, as they provide an efficient way for the operating system to interact with and react to its environment. The alternative – having the operating system "watch" the various sources of input for events (polling) that require action – can be found in older systems with very small stacks (50 or 60 bytes) but is unusual in modern systems with large stacks. Interrupt-based programming is directly supported by most modern CPUs. Interrupts provide a computer with a way of automatically saving local register contexts, and running specific code in response to events. Even very basic computers support hardware interrupts, and allow the programmer to specify code which may be run when that event takes place" to " Interrupts are system calls, generated by user or software using operating system. They provide the efficient way for the operating system to interact with user and the system components. Most modern CPU's support interrupt-based programming. This makes the system responsive and efficient." VidyaVinaya (talk) 18:28, 26 August 2020 (UTC)

The suggested rewording makes no sense at all. Interrupts are not necessarily system calls, they are not generally generated by the user or software using the operating system. DOS did use software interrupts as system calls, as a means to do an indirect jump so that BIOS and DOS routines were not tied to specific addresses. This was essentially an implementation detail. Interrupts are no more efficient than normal system calls – indeed they almost inevitably cause a context switch which a straightfoward subroutine call does not. The proposed rewording seems to show a basic misunderstanding of what interrupts are used for. In most modern systems (even embedded systems), very little code is run under interrupt: instead, the interrupt will generally just add something to the scheduler's event queue and return pronto, if for no other reason than interrupts generally operate in a privileged mode of execution. (There's all kinds of other potential problems with priority inversion and so forth., which a good scheduler should sort out.) Actually, embedded systems – especially safety-critical systems – often do poll hardware rather than use hardware interrupts, because it makes for a more deterministic system. The reason the original text is somewhat long is that it is a far subtler balance than the proposed rewording makes out. I suggest rejecting the req8est. 84.236.27.182 (talk) 06:29, 2 October 2020 (UTC)

 Not done @VidyaVinaya: I agree with this IP editor that your suggested edit is a fundamental misunderstanding of how modern operating systems work. If anything, since interrupt handlers can in general require a complete context switch in effect, interrupts can be quite inefficient.--Jasper Deng (talk) 06:39, 2 October 2020 (UTC)

The phrase "operating system" can refer to important systems other than software systems. For example, capitalism, democracy, mass communications, journalism, internet, and other institutions create the social, political, and economic operating systems we live in. I suggest creating a disambiguation page that lists these broader operating systems. See, for example: https://en.wikiversity.org/wiki/Living_Wisely/Improving_our_Social_Operating_Systems --Lbeaumont (talk) 12:02, 28 September 2020 (UTC)Thanks!

Disagree Wikipedia is not a dictionary and that use of the term is extremely uncommon (I was able to find just one book using it, nothing more than that). The page you mentioned above was written by yourself - Daveout(talk) 12:32, 28 September 2020 (UTC)

Disagree To disambiguate you would first need another article (or section) for it to be disambiguated from. Even then, this is clearly the primary topic. If you can link to relevant text elsewhere in WP, just add a hatnote. I think what you are describing are just examples of systems. 84.236.27.182 (talk) 06:53, 2 October 2020 (UTC)

Large swaths of the article are written as though every computer was a microprocessor. Many of the OS concepts predate microprocessors, and most of the referencesa to microprocessors violate WP:NPOV. --Shmuel (Seymour J.) Metz Username:Chatul (talk) 23:49, 30 June 2021 (UTC)

Not all operating systems have human users. Or, running a display panel is just another task for the operating system. I speculate most computers don't run Windows because most computers are embedded in non-computery things like engine control systems or flashlights. --Wtshymanski (talk) 00:31, 20 July 2021 (UTC)

I question this sentence in the article: "When an interrupt is received, the computer's hardware automatically suspends whatever program is currently running, saves its status, and runs computer code previously associated with the interrupt." This seems to be co-mingling the Interrupt Service Routine (ISR) and the Process Control Block (PCB) together. The ISR is in hardware but the PCB is in the OS (software). The word "status" seems to mean "registers". Upon a context switch, the OS copies the registers to the PCB -- a software process. (Or maybe it done in hardware now. Please educate me.) Also, "computer code previously associated with the interrupt" sounds like the ISR. The article should be specific and differentiate between the hardware functions and the OS functions. Timhowardriley (talk) 14:45, 20 January 2022 (UTC)

That sentence is in Operating system#Components - #Kernel - #Interrupts, which is not specific to a PC architecture, and is relevant to systems without interrupt pins. In general, there is a hardware context and a software context; an interrupt causes the hardware to save the hardware context, switch to a more privileged context and transfer control to a first level interrupt handler. Code in or called by the interrupt handler may eventually switch back to the original context or may select a different process and switch to its software context.

Status may be as simple as a PC or PSW, or may include a large set of registers.

Operating system code called from the interrupt routines may switch to, e.g., a new Address Space Control Block (ASCB) and Task Control Block (TCB), a new PCB, a new page table, a new segment table, but that is well after the context switch in the interrupt. --Shmuel (Seymour J.)
