Among the many types and categories of software on the top rung of the hierarchy of the operating systems are located.This large-scale and complex types of programs, acting directly as a layer between the computer hardware or any other device and separate applications, which help the user to perform specific tasks.
operating system must take control of all the main action of the computer and all peripherals.However, one can say that the operating system is only available for the PC as such.Any sophisticated electronic device that performs operations and counted by the processor will need the operating system.Now there are special kinds of operating systems for smartphones and tablet PCs, etc.
operating system is needed in order for the user to manage all processes.This kind of shell, which provides quick and easy access to the main functions of the computer or device.It serves as a medium to run other applications and programs.Types of operating systems are divided in the first place on the properties and features, as well as the type of device for which they are intended.
As already mentioned, any operating system takes control of the "iron" stuffing computer or any other device that controls the allocation of memory and CPU performance.One of the main problems is the input and output data as any computer to work with the new data.
There are types of operating systems with different types of file systems, as well as methods of treatment processes, interaction with other machines using the memory.For the most user remains evident in the first interface, how it is useful depends on the popularity of particular operating systems, and methods are also implemented.
We must not forget that the OS itself also takes some of the available resources - memory, CPU, and disk space.Accordingly, the best operating system - is the one that has a high degree of functionality, but it remains very low system requirements.
There are many varieties of operating systems, each of which has certain characteristics, depending on the tasks.For example, some operating systems are designed to work in multi-user networks, others are designed for a single user and a single PC (OS Windows).
towards the user can select categories such as usability, interface, ease of administration, openness, value, word length, etc.
Using his powers, the user can remove both the operating system and install a new one.However, it will be difficult to do, since the need to use additional features.The operating system itself can not remove.
In the situation today, the variety can be identified for the home computer operating system for mobile devices.In the first case, the leader is OS Windows from Microsoft.In the second case the situation is different for a long time there was no specific leader, but now it is a product from Google OC Android.It's quite convenient operating system with a free code, and supports a large number of content developers and software.In addition, the popularity of Apple devices account for the fact that a fairly high percentage of iOS.However, there are many other operating systems for computers and mobile devices, which simply did not win such a high popularity or for some reason their development has been suspended.
