An operating system (OS) is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer A computer is a machine that manipulates data according to a set of instructions that acts as a host for computing applications Application software is computer software designed to help the user perform a particular task. Such programs are also called software applications, applications or apps. Typical examples are word processors, spreadsheets, media players and database applications run on the machine. As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware A [[personal computer [PC]] are made up of multiple physical components of computer hardware, upon which can be installed an operating system and a multitude of software to perform the operator's desired functions. This relieves application programs from having to manage these details and makes it easier to write applications. Almost all computers (including handheld computers A mobile device is a pocket-sized computing device, typically having a display screen with touch input or a miniature keyboard. In the case of the personal digital assistant (PDA) the input and output are combined into a touch-screen interface. Smartphones and PDAs are popular amongst those who require the assistance and convenience of a, desktop computers A desktop computer is a personal computer in a form intended for regular use at a single location, as opposed to a mobile laptop or portable computer. Prior to the wide spread of microprocessors, a computer that could fit on a desk was considered remarkably small. Desktop computers come in a variety of types ranging from large vertical tower cases, supercomputers A supercomputer is a computer that is at the frontline of current processing capacity, particularly speed of calculation. Supercomputers were introduced in the 1960s and were designed primarily by Seymour Cray at Control Data Corporation , and led the market into the 1970s until Cray left to form his own company, Cray Research. He then took over, video game consoles A video game console is an interactive entertainment computer or modified computer system that produces a video display signal which can be used with a display device to display a video game. The term "video game console" is used to distinguish a machine designed for consumers to buy and use solely for playing video games from a personal) as well as some robots A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro-mechanical machine which is guided by computer or electronic programming, and is thus able to do tasks on its own. Another common characteristic is that by its appearance or movements, a robot often conveys a sense that it has intent or agency of its own, domestic appliances (dishwashers, washing machines), and portable media players A portable multimedia player , is a consumer electronics device that is capable of storing and playing digital media. Digital audio players (DAP) that can also display images and play videos are PMPs. Like DAPs, the data is typically stored on a hard drive, microdrive, or flash memory. Other types of electronic devices like cellphones are use an operating system of some type.[1] Some of the oldest models may, however, use an embedded operating system An embedded operating system is an operating system for embedded computer systems. These operating systems are designed to be very compact and efficient, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also real-time operating that may be contained on a data storage device A data storage device is a device for recording information (data). Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.
Operating systems offer a number of services to application programs and users. Applications access these services through application programming interfaces An application programming interface is an interface that a software program implements in order to allow other software to interact with it, much in the same way that software might implement a user interface in order to allow humans to interact with it (APIs) or system calls In computing, a system call is the mechanism used by an application program to request service from the operating system based on the monolithic kernel or to system servers on operating systems based on the microkernel-structure. By invoking these interfaces, the application can request a service from the operating system, pass parameters, and receive the results of the operation. Users may also interact with the operating system with some kind of software user interface like typing commands by using command line interface A command-line interface is a mechanism for interacting with a computer operating system or software by typing commands to perform specific tasks. This text-only interface contrasts with the use of a mouse pointer with a graphical user interface (GUI) to click on options, or menus on a text user interface (TUI) to select options. This method of (CLI) or using a graphical user interface A graphical user interface is a type of user interface item that allows people to interact with programs in more ways than typing such as computers; hand-held devices such as MP3 Players, Portable Media Players or Gaming devices; household appliances and office equipment with images rather than text commands. A GUI offers graphical icons, and (GUI, commonly pronounced “gooey”). For hand-held and desktop computers, the user interface is generally considered part of the operating system. On large multi-user systems like Unix Unix is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna. Today the term Unix is used to describe any operating system that conforms to Unix standards, meaning the core operating system operates the same and Unix-like A Unix-like operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification systems, the user interface is generally implemented as an application program that runs outside the operating system. (Whether the user interface should be included as part of the operating system is a point of contention.)
While the most common operating systems are now found in cellphones and automobiles, other contemporary operating systems include BSD Berkeley Software Distribution is the UNIX operating system derivative developed and distributed by the Computer Systems Research Group of the University of California, Berkeley, from 1977 to 1995, Darwin (Mac OS X) Darwin is an open source POSIX-compliant computer operating system released by Apple Inc. in 2000. It is composed of code developed by Apple, as well as code derived from NeXTSTEP, BSD, and other free software projects, Linux Linux is a generic term referring to Unix-like computer operating systems based on the Linux kernel. Their development is one of the most prominent examples of free and open source software collaboration;[citation needed] typically all the underlying source code can be used, freely modified, and redistributed, both commercially and non-, SunOS (Solaris/OpenSolaris) SunOS is a version of the Unix operating system developed by Sun Microsystems for their workstation and server computer systems. The SunOS name is usually only used to refer to versions 1.0 to 4.1.4 of SunOS. These versions were based on BSD Unix, while SunOS version 5.0 and later are based on UNIX System V Release 4, and are marketed under the, and Windows NT (XP/Vista/7) Windows NT is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. It was originally designed to be a powerful high-level-language-based, processor-independent, multiprocessing, multiuser operating system with features comparable to Unix. It was intended to complement consumer versions of. While servers generally run Unix or some Unix-like operating system, embedded system markets are split amongst several operating systems,[2][3] although the Microsoft Windows Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces . Microsoft Windows came to dominate the world's personal line of operating systems has almost 90% of the client PC market.

Q. I changed my disk drive letters on one of my operating system but i think that i made a mistake. I'm now on other operating system but i was wandering if i can change it on this system? Well apparently i have two windows xp operating systems, but the one i changed, cannot start up again, as it freezes when the welcome sign shows up, except it doesnt show the welcome sign it shows the windos xp sign. Any help?

A. You don't need to use another system. if we're talking Windows here, just boot up the system, and go to the Disk Manager in the Administrative tools. You can edit the drive letters there.
