Basic operating system functions
So, take your desktop PC. A typical desktop computer - a system unit (basic iron), monitor (line display on regular device), a keyboard and mouse (main input device), additional peripherals (speakers, headphones, scanners, printers, plotters, MFI and others) and software component (operating system, user programs, system programs ...). In this regard, the functions of the operating system perform:

• Providing user intuitive interface to work;

• Correct relationship of all components in the system unit;
  Accurate and integrated work between all elements of the PC;

• Possibility to manage PC programs and components.

If you take a laptop, notebook or tablet PC, then the features of the operating system they will be the same. In fact, the situation is somewhat more global. OS includes:

• A shell for the user;

A - Driver - is a program for managing your PC parts and their coordination work together

Some Hardware:

You talk, what features of the operating system, for that answer, here it is necessary to divide it into two types: user (interface, executive) and iron (negotiation, management). In other words, all the processes running in the PC - is a complex machine code. The user finds it difficult to understand, moreover, it is very cumbersome at times. Imagine how many times you have introduced data to open a folder (for example). The older generation of users has been familiar with the operating system with a minimal interface. - The reason for the operating system for any user is the interface and navigation, most users have this association with its functions.

In general, users like to install a variety of applications that affect the operation of their computer components or enhance information content. The functions of the operating system expanded somewhat in our time. Due to the fact that there was practically free access to the Internet, the operating system had to take on some more features. First - interact with a new type of equipment. Devices such as network printers, routers, access points, and modems require special drivers. But it is shown on the whole structure. By installing the printer driver (eg), you not only say the OS on the new devices, but also automatically adjust the program in which it is possible to print.
Second - the security features of the OS and sponsored programs. The development of anti-virus software is essential in the era of global development of the Internet. The operating system has a firewall in addition to any computer. We usually carry out, so the user will not think the functions are performed by the operating system. He only uses computers. We came to another important issue - the disappearance of OS operation for the user. So, too, and there was multitasking. As far as the time when the user was equipped with 1 GB hard drive, OS takes 700 MB. That means all the other functions you have on board are 300 MB and 64 MB as much RAM. It is suitable for general typing, without the use of computer graphic content.

But this is history. Modern computers have multicore processors, dozens of RAM, terabytes of stable memory, gigabytes of video and wireless interfaces. It's hard to imagine what an operating system function is currently. Note that Windows 7 requires two dozen gigabytes to install it. This powerful animation "weights" due to the user's usability, to facilitate the regular presence of a large amount of additional programs and more.

Of course, since the emergence of "water under the bridge" packet data, and user-friendly interface more (about 20 years old - single). OS is for us the most important program of any kind on our computer. At present, the popular operating system has an open structure - individually for fine tuning. This is very well seen in the mobile gadget market. Phones are completely losing their positions smartphones. A little more and it will continue.
