1. Operating system

   An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose desktop operating system is Microsoft Windows with a market share of around 76.45%. macOS by Apple Inc. is in second place (17.72%), and the varieties of Linux are collectively in third place (1.73%). In the mobile sector (including smartphones and tablets), Android's share is up to 72% in the year 2020. According to third quarter 2016 data, Android's share on smartphones is dominant with 87.5 percent with also a growth rate of 10.3 percent per year, followed by Apple's iOS with 12.1 percent with per year decrease in market share of 5.2 percent, while other operating systems amount to just 0.3 percent. Linux distributions are dominant in the server and supercomputing sectors. Other specialized classes of operating systems (special-purpose operating systems)), such as embedded and real-time systems, exist for many applications. Security-focused operating systems also exist. Some operating systems have low system requirements (e.g. light-weight Linux distribution). Others may have higher system requirements. Some operating systems require installation or may come pre-installed with purchased computers (OEM-installation), whereas others may run directly from media (i.e. live cd) or flash memory (i.e. USB stick).

1. Operating system

   An operating system is a collection 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 usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems include Android, BSD, iOS, GNU/Linux, OS X, QNX, Microsoft Windows, Windows Phone, and IBM z/OS. All these, except Windows and z/OS, share roots in UNIX.

1. operating system

   [techspeak] (Often abbreviated ‘OS’) The foundation software of a machine; that which schedules tasks, allocates storage, and presents a default interface to the user between applications. The facilities an operating system provides and its general design philosophy exert an extremely strong influence on programming style and on the technical cultures that grow up around its host machines. Hacker folklore has been shaped primarily by the Unix, ITS, TOPS-10, TOPS-20/TWENEX, WAITS, CP/M, MS-DOS, and Multics operating systems (most importantly by ITS and Unix). See also timesharing.

Examples of operating system in a Sentence

1. Alan Gottlieb:

   This is an abuse of power by the Massachusetts attorney general, it is no different than President Obama’s illegal anti-gun executive orders. If these firearms were legal yesterday, they are legal today, Alan Gottlieb said in an email to FoxNews.com. This ban on semi-auto firearms must be stopped before gun prohibitionists in other states try to enact similar bans by fiat, Alan Gottlieb said. The debate is the latest example of the long-running argument between Second Amendment purists and gun control advocates about whether new firearms laws make people safer. Indeed, the fact that Massachusetts has so few murders committed using assault weapons could be seen as evidence that the original ban was successful. The enforcement notice from the attorney general says a weapon is considered a copy or duplicate if its internal operating system is the same as those of a specifically-banned weapon or if the gun has key functional components that are interchangeable with those of a banned weapon. Such weapons would include copies of the Colt AR-15 and the Kalishnikov AK-47, which are both prohibited by the state's assault weapons ban. Healey's office claims gun makers produce and sell what they call.

2. Melvic Smith:

   You could accomplish some of the functionality by duct-taping an iPhone to your gun. However what we offer is the world's first truly embedded operating system.

3. Linus Torvalds:

4. Mary R. Thompson:

   Andrew is the operating system of the future and always will be.

5. Evan Osnos:

   It's down a few hundred minutes from yesterday, but it looks like we've still got 25 million minutes to go, the consensus seems to be that we're using an old operating system that won't let us restart fresh from iTunes.
