Classification of the operating systems

He is a operating system that set of programs that allows a user to execute one or more tasks on the computer. In this way, the operating system is the intermediary between the user and the computer, being the basic software that provides the interface between all the rest of the programs and the Devices hardware (such as monitor, keyboard, speakers, or microphone).

Functions of operating systems

In this way, the functions that every operating system comes to fulfill are several, but the first of all stands out, which is initialize hardware of the computer; then provide basic routines to control devices; manage, rearrange and interact tasks with each other; and above all maintain the integrity of the system. Both threats (viruses) and prevention tools (antivirus) are designed precisely for the security of operating systems.

Structure of operating systems

In effect, the structure of an operating system is made up of five large 'layers' or stages, each of which has a series of associated functions:

Classification of the operating systems

There are different ways to classify and subdivide operating systems. The criteria will be listed below, and then the different groups that are formed based on them:

The history of Windows

Different operating systems are offered on the market, each of which has its own set of advantages and disadvantages. Among all, the most popular is the system Windows, which was founded in 1975 by Bill Gates and introduced the first version of an operating system that rapidly evolved and incorporated functions. The first version was released in 1981 with a few functions, but only four years later the system became popular in the first version of Windows, 1.0.

Since then, the benefits have increased at an exponential speed, and versions of Windows such as 98, 2000 or XP were very popular: the latest is Windows 7, released in 2008 with notable advancements such as support for virtual hard drives and improved performance on multicore processors. Something similar happened with the advancement of other operating systems, among which the open Linux system stands out.

Operating systems on the Internet

Of course the conventional definitionHe of operating systems is long before the existence of the Internet, which came to reconfigure the whole vision of computers. It is possible that the different operating systems give way to a single Internet operating system, where everything depends on the 'cloud'. In this way, the use of computers would notably change because it would not be necessary to download or install any type of program, as happens in servers like Orkut.

Based on the existence of an Internet network, a new classification of operating systems, referring to the way in which users access services: network operating systems are those that have the ability to interact with operating systems of other computers in order to exchange information, while distributed operating systems they cover network services, but also integrate resources in a single virtual machine that the user accesses in a transparent way.
