Explain the purpose of operating systems (P2) The operating system whatever it may be (Windows or

An operating system (OS) is designed to act as an interface between the computer and its user. The Windows Server OS is a platform that you can use to build an infrastructure of connected applications, networks, and Web services. Originally codenamed Windows Server "Longhorn," Windows Server 2008 is built from the same code base as Windows Vista .

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

Software utilities can do many different things and offers many different features and tools that help the user to improve system performance, such as clearing junk files from the storage device, update device drivers, scan for viruses or spyware, optimise memory, defrag the hard disk, manage the start-up programs and help backing up or recovering files.

Operating systems and application software are essential in the running of computers. The operating system is the most important piece of software on a computer. It controls the computers software/hardware, memory and processing. It also allows the user to control the computer without knowing its operating language. An example of an operating system is Mac OS X. Application software is often designed for a specific purpose such as word processing, Web browsers or spreadsheets etc. These applications can often be used to do other jobs than just the one intended. For example you could use word to edit photos but this is not the applications intended use, so it will not have advanced image-editing features which a program like Photoshop would

What is an Operating System (OS) a person may ask? Having an operating system, helps to control applications that run on the software and hardware that are on any user’s computer. These applications are set within a layered appearance, just as a hierarchy looks like. This is how it looks:

________ can be commercial software or software developed in-house and is used to perform a variety of tasks on a personal computer.

Such programs are used to detect and usually eliminate viruses. Anti-virus software can be purchased or downloaded via the internet. Care should be taken in selecting anti-virus software, as some programs are not as effective as others in finding and eliminating viruses or malware. Also, when downloading anti-virus software from the Internet, one should be cautious as some websites say they are providing protection from viruses with their software, but are really trying to install malware on your computer by disguising it as something else.

The (OS) operating system is the best example of system software. An operating system manages a computer’s hardware and software and provides sources for computer programs. Most application programs require an operating system to function. There are numerous operating systems (OS) one may choose to install on their computer. Each OS will have different looks and functions that differ from the others. Windows 10 is a popular OS that is used widely around The United States. System software and application programs are the two main types of system software.

The information technology field is a field that covers a vast amount of technologies and ideas that have evolved to be much more than what they were during the infancy of the technology movement. Perhaps the greatest innovator and most recognizable face of the field is Bill Gates, the creator of the Windows operating system. Windows revolutionized the way the public interacted with their personal computers and catapulted the devices into the majority of American’s homes. Running counter to Windows, and taking a completely open source route for ease of access and distribution is Windows rival Linux. Linux has a very different approach to how the PC should operate and had a number of different versions that are tailored to individual user’s needs. All of these different operating systems have at least one thing in common however. The ability to run on a personal computer. The personal computer, or PC, the personal computer is a general-purpose computer that make it useful for individuals and are intended to be operated by an end user.

On personal computers, there are two main types of software: operating systems, and applications software. Application software is a program designed to complete a specific purpose under control from a user. Application software is specialized, as in it perform a specific task. For example, Microsoft Word is a word processor, and is used for typing. Windows explorer is used to browse saved files, and does that job well.

Windows Operating System exists in the family of the various virtual Operating Systems provided by Microsoft. It is a part of the OS from Microsoft that typically serve the IBM PC compatible machines and devices. The present active Windows include Windows NT, Embedded and Windows Phone. They do have subfamilies that include Windows CE and Server. The defunct family includes the 9x system while Windows 10 Mobile is inactive.

The computer is made up of many components and the operating system is just an interface between the user and the computer hardware. Software that runs on a computer must be designed to meet the requirements of the operating system and not exceed the hardware limitations to run effectively on a

Every computer needs an operating system to operate. The operating system controls everything that the computer does, the master controller. It is the gasoline of the computer. According to Parsons and Oja (2014), they state that an operating system is “the integral part of virtually every computer system. It fundamentally affects how you can use your computer” (p 184). Most computers are bought with the operating system already installed.

An operating system is an interface between a user and the hardware of a computer. It is just a set of software that manages computer hardware and controls the operations on the computer. Operating system is the base of the application programs because they cannot contact the hardware directly. It does not do any work itself; it just provides an environment in which the other programs on a computer can run. Therefore, when a user enters or sends a command the operating system makes sure that the command is executed or not, if not it displays a message explaining the error. Without operating system a computer is of no use it is just a metal block.
