An operating system is the most important software that runs on a computer.

Operating system and user interface

This is a list of operating systems. Computer operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. Criteria for inclusion is notability, as shown either through an existing Wikipedia article or citation to a reliable source. See also Mobile Operating systems.

Five Common Operating Systems

An Operating System performs all the basic tasks like managing files, processes, and memory. Thus operating system acts as the manager of all the resources, i. Thus, the operating system becomes an interface between user and machine. Types of Operating Systems: Some widely used operating systems are as follows-. There is an operator which takes similar jobs having the same requirement and group them into batches. It is the responsibility of the operator to sort jobs with similar needs.

Whether it's a desktop or laptop computer, a smartphone or a video game system, every modern computer needs an operating system. That's the core software on the computer that sits between application software and the hardware, distributing memory and computing resources to apps, managing files and enforcing security rules. Operating systems define how a computer stores files, switches between different applications, manages memory, keeps itself secure, and interacts with peripherals like printers and cameras. Different operating systems take different approaches to all of these, which is why you normally can't run a Windows program on a Macintosh computer and why permissions look different on an Android phone than on an iPhone. Some operating systems are designed by groups of people around the world, like the open source, freely available operating system Linux, while others are commercial products made by one company, such as Microsoft's Windows and Apple's macOS. Different operating systems run on different types of hardware and are designed for different types of applications. Your computer or smartphone comes equipped with an OS, but you can install another one in some cases.

Operating Systems

Within the broad family of operating systems, there are generally four types, categorized based on the types of computers they control and the sort of applications they support. The categories are:. It's important to differentiate between multi-user operating systems and single-user operating systems that support networking. Windows and Novell Netware can each support hundreds or thousands of networked users, but the operating systems themselves aren't true multi-user operating systems.

All application such as games, MS office, Firefox requires a suitable environment to execute and perform their task. The operating system helps the user to interact with the system without knowing to work on with the computer language. It is not feasible for anyone to use any smartphones or computers without deploying the operating system.

Вся моя жизнь - это любовь к моей стране. Вся моя жизнь - это работа здесь, в Агентстве национальной безопасности. Сьюзан слушала молча. - Как ты могла догадаться, - продолжал он, - вскоре я собираюсь выйти в отставку. Но я хотел уйти с высоко поднятой головой.

Я читал электронную почту Танкадо уже в течение двух месяцев. Как ты легко можешь себе представить, я был шокирован, впервые наткнувшись на его письмо Северной Дакоте о не поддающемся взлому коде, именуемом Цифровая крепость. Я полагал, что это невозможно. Но всякий раз, когда я перехватывал очередное сообщение, Танкадо был все более и более убедительным.

 - Du hast einen Ring. У вас есть кольцо. - Проваливайте! - зарычал немец и начал закрывать дверь. Беккер не раздумывая просунул ногу в щель и открыл дверь.

Когда Беккер наконец вышел из Гиральды в Апельсиновый сад, утреннее солнце уже нещадно пекло.

Черт возьми, - подумал Бринкерхофф, разглядывая ее серое кашемировое платье, - или я старею, или она молодеет. - Еженедельные отчеты.  - Мидж улыбнулась, помахивая пачкой документов.

Это открытие было болезненным, однако правда есть правда. Стратмор скачал файл с Цифровой крепостью и запустил его в ТРАНСТЕКСТ, но программа Сквозь строй отказалась его допустить, потому что файл содержал опасную линейную мутацию. В обычных обстоятельствах это насторожило бы Стратмора, но ведь он прочитал электронную почту Танкадо, а там говорилось, что весь трюк и заключался в линейной мутации.

 Чед? - В дверях его кабинета возникла Мидж Милкен, эксперт внутренней безопасности Фонтейна. В свои шестьдесят она была немного тяжеловатой, но все еще весьма привлекательной женщиной, чем не переставала изумлять Бринкерхоффа. Кокетка до мозга костей, трижды разведенная, Мидж двигалась по шестикомнатным директорским апартаментам с вызывающей самоуверенностью.

    Whether it's a desktop or laptop computer, a smartphone or a video game system, every modern computer needs an operating system.

    As already mentioned, in addition to the hardware, a computer also needs a set of programs—an operating system—to control the devices.
