Many users of modern computers very often face system programs, although in some cases they do not even suspect they are dealing with them. Some people generally try not to get into the jungle, so that they can not break the operating system. Probably, it is necessary to understand what system programs are, what kinds of system programs are known today. In passing, the question of what they represent in terms of functional will be considered. But first things first.
System programs are what?
So, now we will not particularly go into the subtleties of the work of system applications. An ordinary user does not need this. Let's consider the basic questions connected with understanding of what system programs meet in general. In addition, you can learn a little about their classification.
In simple terms, system programs are designed to communicate between the installed operating system, the hardware components of the computer terminal, applications and the user. And here the user? Yes, it is simply that the user communicates with the user via a graphical interface, through which he can access certain functions embedded in the system itself.
Classes of system programs
Today there are many classifications of system software. However, basically they can be divided into several classes or groups. First of all, these are system management programs, data processing facilities, basic minimum sets for operating the OS and utility utilities.
Needless to say, each class can be divided more and more. For example, operating system programs, in fact, represent the most common OS, which today can count dozens. The same is observed, say, in the service software, where a huge number of various utilities for a variety of purposes are presented (working with hard drives, editing the registry, removing computer "garbage", uninstalling applications, etc.).
One of the most important components in any computer system are drivers, also representing system programs. These are small special applications responsible for the correct functioning of any "iron" device. Who has not come across the concept of a video card driver or sound card?
It's the drivers, so to speak, that help the system to properly configure the operation of any component. As a rule, even with the purchase of a computer or laptop, a special drive with drivers is always included in the kit. This is due to the fact that, depending on the manufacturer, the same Windows OS does not always correctly recognize any device, despite the extensive catalog present in their distributions.
In some cases, Windows can install the most appropriate driver, and the device does not work. Here, the installation of original "native" drivers provided by the manufacturer of the "iron" equipment comes to the rescue.
Standard Windows system programs
As it should be, Windows has its own system programs. These are usually utilities that are available to the user in the Start menu in the All Programs / Administration, Maintenance and Standard sections, and some in the Control Panel. In standard programs, in addition to system utilities, there is also a minimal set of applications needed for work.
Unfortunately, in terms of system programs, Windows OS does not differ much. Most processes are hidden from the user's eyes. This is understandable, because the completion of some process or the removal of the system service can have disastrous consequences for the entire system as a whole.
Some curious users often wonder how to remove the system program. The answer is simple: no way! Built-in system utilities in Windows are not deleted. Of course, you can delete entries and keys in the registry, but the system will still restore default values upon reboot. In addition, after removal, it is possible that the OS will not work at all, so it's better not to take risks.
System and Data Recovery
An important role today is played by the possibility of restoring the system, or, as they say, rolling back to the previous state, determined by the control point. In versions of Windows, this feature appeared, starting with the version of Windows Millennium. However, there the user did not have direct access to the means of recovery. Later such an opportunity became available in the form of the "Center for Archiving and Restoration."
Working with images
To work with images, Windows does not provide the best tools, which is obvious. But third-party developers went much further in this respect.
Utilities such as UltraISO, Daemon Tools, Alcohol 120%, etc., have much more capabilities than standard Windows tools.
Perhaps for Windows anti-virus packages are the most popular part of system programs, because the family of Windows operating systems is the most vulnerable to viruses. In the system itself, there is so much gaps that it's no wonder that Microsoft is constantly releasing some updates, most often concerning patching security holes.
In this case, it is best to turn to professionals. Here you can find a variety of products from Kaspersky Lab, Eset, Norton, free AVG, Avira, Panda, and so on.
What system programs are provided for testing? Basically, these are utilities for checking the operability of the OS itself and its "iron" components. In some cases, such applications can combine optimization functions or even work as a means for overclocking processors or video cards.
These programs can be divided into information applications and utilities that can correct errors or restore the performance of a component. By purely informational one can include utilities such as CPU-Z or Everest, and to restoring - Victoria or HDD Regenerator.
Optimizers are designed to speed up the operation of the operating system by fixing errors, removing unnecessary computer "garbage", defragmenting disks , etc. Windows certainly has its own tools in the form of the same defragmenter to speed up data access and run applications or a disk cleaning system .
However, as practice shows, they are inferior to specialized utilities such as Advanced System Care, CCleaner, Glary Utillities, Windows 7 Manager and many others.
Working with archives is an integral part of any system. In Windows, there is a built-in WinZIP archiver. I must say that this is not Microsoft's own development. It was created specifically on the basis of an old good ZIP archiver.
The best in this area are WinRAR, WinZIP, 7-Zip and many others. Each utility has its own specificity, but in general they work in almost the same way.
There are many additional categories that include system programs. This includes ActiveX controls. The most striking example - Adobe Flash Player - a program for playing streaming video on the Internet. As you already know, in the Windows OS itself nothing like this.
No less important component can be called all sorts of sets of codecs and decoders, without which it will be impossible to watch a video or play audio. Here the leading position belongs to the K-Lite Codec Pack.
The tools for working with PDF documents or Internet resources containing such data are very popular. Here, programs such as Adobe Reader come to the rescue. And such utilities in the process of installation can even integrate into the system itself and into Internet browsers.
This includes many system programs responsible for access to the Internet or the creation of local networks, without which the modern world can not be imagined.
In principle, we have considered only general concepts of system programs. In fact, if you dig deeper, you can enumerate them indefinitely. It is clear because the development of computer equipment is not worth it. That is why there are new classes of system programs that are already responsible for completely different directions in the work. So you can only guess what the system applications will become when quantum computers appear ...
