An operating system is a powerful, and usually large, program that controls and manages the hardware and other software on a computer.

All computers and computer-like devices require operating systems, including your laptop, tablet, desktop, smartphone, smartwatch, and router.

Examples of Operating Systems

Laptops, tablets, and desktop computers all run operating systems that you've probably heard of. Some examples include versions of Microsoft Windows (like Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP), Apple's macOS (formerly OS X), Chrome OS, BlackBerry Tablet OS, and flavors of the open source operating system Linux.

Your smartphone runs an operating system, too, probably either Apple's iOS or Google's Android. Both are household names but you may not have realized that they are the operating systems running on those devices.

Servers, like those that host the websites you visit or serve the videos you watch, typically run specialized operating systems, designed and optimized to run the special software required to make them do what they do. Some examples include Windows Server, Linux, and FreeBSD.

Software & Operating Systems

Most software applications are designed to work with just one company's operating system, like just Windows (Microsoft) or just macOS (Apple). Saunders nclex review online test.

A piece of software will clearly say which operating systems it supports and will get very specific if necessary. For example, a video production software program might say it supports Windows 10, Windows 8, and Windows 7, but does not support older versions of Windows like Windows Vista and XP.

Software developers also often release additional versions of their software that work with other operating systems. Coming back to the video production program example, that company might also release another version of the program with exactly the same features but that only works with macOS.

It's also important to know whether your operating system is 32-bit or 64-bit. It's a common question you're asked when downloading software. See How to Tell If You Have Windows 64-bit or 32-bit if you need help.

Special types of software called virtual machines can actually mimic 'real' computers and run different operating systems from within them. See What Is a Virtual Machine? for more on this feature.

Understanding Operating Systems Pdf

An operating system is a program that manages a computer’s hardware. It also provides a basis for application programs and acts as an intermediary between the computer user and the computer hardware. An amazing aspect of operating systems is how they vary in accomplishing these tasks. Mainframe operating systems are designed primarily to optimize utilization of hardware. Personal computer (PC) operating systems support complex games, business applications, and everything in between. Operating systems for mobile computers provide an environment in which a user can easily interface with the computer to execute programs. Thus, some operating systems are designed to be convenient, others to be efficient, and others to be some combination of the two.

Operating Systems Concepts Pdf

Before we can explore the details of computer system operation, we need to know something about system structure. We thus discuss the basic functions of system startup, I/O, and storage early in this chapter. We also describe the basic computer architecture that makes it possible to write a functional operating system. Because an operating system is large and complex, it must be created piece by piece. Each of these pieces should be a well-delineated portion of the system, with carefully defined inputs, outputs, and functions. In this chapter, we provide a general overview of the major components of a contemporary computer system as well as the functions provided by the operating system. Additionally, we cover several other topics to help set the stage for the remainder of this text: data structures used in operating systems, computing environments, and open-source operating systems.
