Main types of operating systems
Among the numerous species and categoriessoftware at the very top of the hierarchy are operating systems. These are large-scale and complex kinds of programs acting directly as a layer between the hardware of a computer or any other device and separate applications that help the user perform specific tasks.
The operating system must take controlall the basic actions of the computer, as well as all peripheral devices. However, you can not say that the OS exists only for the PC as such. Any sophisticated electronic device that performs and calculates operations using a processor will need an operating system. Now there are special types of operating systems for smartphones and tablet computers, etc.
The operating system is necessary in order touser could manage all processes. This is a kind of shell that provides quick and convenient access to the basic functions of the computer or device. It acts as the environment for running other applications and programs. The types of operating systems are divided, first of all, by their properties and capabilities, and also by the type of device for which they are intended.
As already mentioned, any operating systemtakes control of the "iron" stuffing of a computer or any other device, controls the allocation of memory and processor performance. One of the main tasks is input and output of information, since any computer must work with new data.
There are types of operating systems with differenttypes of file systems, as well as methods for processing processes, interacting with other machines, using RAM. For the user himself, the interface is first of all noticeable, depending on how convenient it is, the popularity of the particular OS, as well as the implemented methods, depends.
Do not forget that the OS itself also takesSome of the available resources - RAM, processor power and disk space. Accordingly, the best operating system is one that has high functionality, but at the same time it remains undemanding to resources.
Types of OS
There are so many varietiesOperating systems, each of which has certain features, depending on the tasks assigned. For example, some types of operating systems are designed to work in multi-user networks, others are designed for one user and one computer (Windows OS).
In relation to the user, categories such as convenience, interface, ease of administration, openness, cost, bit depth, etc. can be distinguished.
Using his powers, the user can,how to remove the operating system, and install a new one. However, it will be more difficult to do this, since it will be necessary to use additional possibilities. The operating system can not delete itself.
In the situation that has developed in ourselect the OS versions for the home computer and for mobile devices. In the first case, the leader is the Windows OS from Microsoft. In the second case, the situation is somewhat different, for a long time there was no specific leader, but now it is a product from Google OC Android. This is a fairly handy operating system, with free code, and is supported by a large number of content and software developers. In addition, the popularity of Apple's devices explains the fact that the percentage of iOS is quite high. However, there are a lot of other OSes for computers and mobile devices that simply did not win such high popularity or for some reason their development was suspended.
