Operating System

operating system (os) : software that controls the operation of a computer and directs the processing of programs (as by assigning storage space in memory and controlling input and output functions) — Webster   See also OneLook

Operating System (FOLDOC: Free Online Dictionary of Computing)


Operating system (OS) is a set of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs require an operating system to function. — Wikipedia

File system is a method and data structure that the operating system uses to control how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stopped and the next began, or where any piece of data was located when it was time to retrieve it. By separating the data into pieces and giving each piece a name, the data is easily isolated and identified. Taking its name from the way a paper-based data management system is named, each group of data is called a “file.” The structure and logic rules used to manage the groups of data and their names is called a “file system.” — Wikipedia

Running Windows 95 in an “app” is a dumb stunt that makes a good point (Ars Staff, Ars Technica)
You know you love Windows 95, and now it’s an app (Johnny Lieu, Mashable)

  • USB installer tool removes Windows 11’s...
    by Thom Holwerda on July 1, 2022 at 9:32 pm

    An easy workaround for this requirement is the Rufus USB formatting tool, which can create USB install media for Windows and all kinds of other operating systems. Rufus has already offered some flags to remove Windows 11’s system requirement checks from the installer, removing the need for clunky Windows Registry edits and other workarounds. But the beta of version 3.19 will also remove the Microsoft account requirement for new installs, making it easy to set up a new Windows PC with a […]

  • What’s the deal with all those weird...
    by Thom Holwerda on July 1, 2022 at 9:31 pm

    Even thought it was clear this message was the lead-in to a swindle of some kind, I had to pause and admire the craft that went into its composition. Like everyone else, I get scam text come-ons pretty frequently, and they’re always poorly pitched and low-energy. In contrast, this text opened up a rich world, animated by detail and alive with mystery. I didn’t care about packages missing their intended destinations, or Bitcoin investing advice, or whatever scammers usually texted me about, […]

  • Thanks to fans, the weirdest official Doom game...
    by Thom Holwerda on July 1, 2022 at 9:28 pm

    Doom RPG, id’s Doom game for pre-iPhone mobile phones, has been reverse engineerd and ported to Windows. Even id Software’s official “Year of Doom” museum at E3 2019 left this 2005 game unchronicled. That’s a shame, because it was a phenomenal example of id once again proving itself a master of technically impressive gaming on a power-limited platform. And platforms don’t get more limited on a power or compatibility basis than the pre-iPhone wave of candy bar handsets, which Doom […]

  • OpenBSD has two new C compilers: chibicc and kefir
    by Thom Holwerda on June 30, 2022 at 5:54 pm

    In my never ending quest to have oksh support every C compiler in existence, I have ported two more C compilers to OpenBSD. They are chibicc and kefir. As always, let’s review them and at the end I’ll have links to unofficial ports so that you can play around with these C compilers. As you all know, these things are a little over my head, but I know many OSNews readers are far more knowledgeable about and interested in these things than I am.

  • US communications regulator wants TikTok removed...
    by Thom Holwerda on June 30, 2022 at 4:17 pm

    A commissioner with the U.S. communications regulator is asking Apple and Google to consider banning TikTok from their app stores over data security concerns related to the Chinese-owned company. Brendan Carr, a commissioner with the Federal Communications Commission (FCC), has written a letter to the CEOs of both companies, alerting them that the wildly popular video-sharing app does not comply with the requirements of their app store policies. I wonder just how big the outcry will be among […]
