Operating System

Introduction

An OS is a group of programs in process with the routines of control operations required to continuously maintain such programs. Any system of computation can be divided into two parts: hardware (technical assurance) and software (assurance programs ). The software can be divided into two classes: system software (software based) that manage the operation of the computer , and software application that performs actions useful to the users.

Among the programs of the system include: operating systems (the most important of the whole), compilers , interpreters, editors, etc..

Discussion

An operating system (OS) is software that acts as an interface between hardware devices and user programs, or yourself to use a computer . It is responsible to manage, coordinate and carry out the exchange of resources and acts as an intermediary for the applications running.

Note that it is a common misconception widely called the complete set of tools, operating system, as this is only the kernel and operating environment does not need to be operational and functional. One of the most prominent examples of this difference is the OS Linux , which along with the GNU tools, Linux distributions make calls.

This precision error is due to the modernization of the information held in the late 80's, when the philosophy of structure basic operation of mainframe computers was redesigned to bring it to homes and ease of use, changing the concept of multi-user computer (many users at the same time ) for a single user system (only one user at a time) easier to manage. (See AmigaOS, BeOS and MacOS as the pioneers of the modernization, when friends were baptized with the nickname of Video Toasters for its capacity for editing video round robin multitasking environment with management of thousands of colors and intuitive interfaces Design 3D programs like Imagine or Scala media , among many others.)

One purpose of an operating system as an intermediary is to manage localization resources and access control hardware, a fact which relieves application programmers from having to deal with these details. They are found in most electronic devices that use microprocessors to operate. (Mobile phones, players, DVD , computers , radios, etc.).

Some of the infrastructure of the World Wide Web is comprised of the Operating System Internet , created by Cisco Systems to manage interconnection equipment such as switches and routers.

Development

Operating Systems, like the hardware of computers, have suffered a series of revolutionary changes called generations. In the case of Hardware, generations have been marked by great advances in the components used, from valves (first generation) transistors (second generation), a circuit integrated (third generation), integrated circuits large and very large scale (fourth generation). Each successive generation of hardware has been accompanied by substantial reductions in cost , size, emission heat and consumption of energy, and significant increases in speed and capacity.

In the mid-80's operating system is created, but not until the output (Windows 95) that can be considered an operating system, it was just a graphical interface (MS-DOS) which was available about ...
