Definition of the Operating System

Bagikan Defining the term "Operating System" may be a simple, but it may also be a very ribet! The readers likely never heard the term "Operating System". May also have related directly or indirectly with these terms. However, not necessarily with regard to explaining what is actually meant by the word "Operating System". Conversely, many also had heard the trademark "WindowsTM 1)" or the term "GNU / Linux 2)", and mengidentikkan name of the Windows CE or GNU / Linux with the term "Operating System" is.

Defining the term "Operating System" may be a simple, but it may also be a very ribet! The readers likely never heard the term "Operating System". May also have related directly or indirectly with these terms. However, not necessarily with regard to explaining what is actually meant by the word "Operating System". Conversely, many also had heard the trademark "WindowsTM 1)" or the term "GNU / Linux 2)", and mengidentikkan name of the Windows CE or GNU / Linux with the term "Operating System" is.

A computer system can be divided into several main components, such as "users", "hardware", and "software". "The users" (users) is a party that utilize the computer system. The user here is not only human, but the program may form other applications, computer or other device. "Hardware" (hardware) is shaped concrete object that can be seen and touched. The device is a hard core of a system, and the provider of source-power (resources) for purposes of computing. Among the "users" and "hardware" there is an abstract layer called the "software" (software). Overall, the software helps users to utilize the power source computation-provided hardware. Software in outline is divided into two, namely the "application" and "Operating System". "Program application" is software that is run by users mencapat for a particular purpose. For instance, we explore the Internet using the application "Browser". Or change (edit) file an application with the "Editor". Meanwhile, "Operating System" can be said is a "software" envelop "hardware to be more easily used by the users through the program application. Operating System is in between the computer hardware and software applications. However, how to determine the exact, location of the border between the "computer hardware" and "Operating System", and especially between "software application" and "Operating System"? For instance, whether the "Internet ExplorerTM 3)" is an application or part of the Operating System? Who is entitled to determine the border? Are the users? What is the need to be discussed soundly through the mailing list? What is the need to be decided by a court? Are the politicians (decay) should submit a plan Law System Operation first? In terms of more detailed, Operating System is defined as a program that set the computer hardware, by providing a platform for applications that are above, and act as a communicator between the user with the hardware. Operating System duty to control (control) and coordinate the use of the hardware for various applications programs for various users. Thus, an Operating System is not a part of computer hardware, and also is not part of the computer software applications, especially of course is not part of the user's computer.

The definition of Operating System can be viewed from different angles. From the perspective of users, the Operating System as a tool to facilitate the use of the computer. In this Operating System should be designed with ease of use, compared to the importance of performance or utilization of the resources. In the environment berpengguna-many (multi-user), Operating System can be seen as tools to maximize the use of the resource-power computer. However, on some computers, the user perspective can be only slightly or not at all. For example, embedded computer in the household equipment such as washing machines and so may have the indicator light to show the current situation, but the Operating System is designed to work without user intervention.
From the perspective system, Operating System can be considered as a means of putting resources-efficient power (Resource Allocator). Operating System is the manager for the power-source, who handles the conflict-demand power source efficiently. Operating systems also manage the execution of applications and operating equipment from M / K (Input / Output). This function also known as a program manager (Control Program). Moreover, the Operating System is a part of a program that runs every time the term is known as the kernel.
From the perspective purpose Operating System, Operating System can be seen as tools that make computers more comfortable to use (Convenient) to run the application and resolve the problem of the user. Another goal is to make the System Operation of the computer into power-efficient.
Can be concluded that the Operating System is an important component of any computer system. As a result, the lessons "Operating System" as an important component of the education system based on "computer science". Operating System concept can be more easily understood, if also hard to understand the type of device used. Similarly vice versa. From the known history that the Operating System and hardware affect each other and complement each other. Structure of an Operating System is very dependent on the hardware that was first used to develop it. While the development of the hardware is influenced from things that are needed by an Operating System. In the sub-section, the following illustration will be given various types of development and the Operating System device and its severity.
