The set of Software that allows the effective resource management of a computer is known as OS or software from system. These programs begin to work as soon as the equipment is turned on, since they manage the hardware from the most basic levels and also allow interaction with the user.

It should be noted that operating systems do not work only on computers. On the contrary, this type of systems are in the most electronic devices What do they use microprocessors: the system software enables the device to fulfill its functions (for example, a mobile phone or a DVD Player).

System software

An operating system allows you to manage the resources of an electronic device.

Main functions of an operating system

The operating system complies with five functions basic: the provision of user interface, the resource management, the File management, the task management and the support service and utilities.

Regarding the user interface, the system ensures that the subject can load programs, access your files and perform other tasks with the computer. Resource management enables hardware address, including the peripherals and the net.

The software system also takes care of the file management, by controlling the creation, elimination and access to them, and the IT task management carried out by end users.

We can also mention that the support service takes care of upgrade the versions, improve the security system, add new utilities, control the new peripherals added to the computer and correct the mistakes of the software.

Windows computer

Microsoft Windows is the most widely used operating system in computers (computers).

The graphical interface

Returning to the interface, we must point out that it is one of the most determining points of the success of an operating system, at least in terms of its massification. In this aspect we must include all those graphic elements that allow us to communicate with the system in general, with all those logical components that are stored on the disk, either temporarily or permanent.

The buttons, icons, bars and menus are some of the elements of the graphical interface through which we can perform different functions, such as opening and saving documents, starting the execution of a program, grouping our shortcuts favorites and modify different properties of our desktop. If developers do not find an easy-to-understand design, they risk the public rejecting their product, even in favor of an inferior one but with a clearer interface.

Operating system and resource management

Resource management is another of the most important aspects, because the use of all the components and peripherals that make up the device depends on its effectiveness. For example, it is useless to have the most modern and sophisticated combination of a motherboard, processor, graphics card, RAM memory and solid state disk on the market if when running a video game it does not offer them absolute priorityInstead, it suffocates them with child processes that the player is not interested in executing.

Since its introduction into the computer market until today, operating systems have undergone changes that are impossible to ignore in terms of their versatility and power. However, one of the aspects that has most aroused the interest of consumers has always been the price. With the rise of free operating systems, debates about the right of companies to charge us for their work have been heard around the world. Alternatives are usually created through the modality Open Source, so that its evolution and its support are lower than what a traditional company can offer. It should be noted that new computers usually come with a pre-installed commercial operating system at a very convenient price.
