System programs for PC

Quite often, many users of computer systems are faced with the question of what constitutes the system programs. With the knowledge of how they work and proper use you can achieve a lot, well, at least to avoid the appearance of errors in the system or speed up (optimize) its work.

System programs for computer: General concepts

As the name implies, programs of this type are special utilities and tools for the regulation of computer systems - from diagnosis all software and “iron” of the components to a maximum use of all capabilities of a PC, even hidden.

In a sense, system programs and application, you can call the layer between the OS and installed software and “iron”. A striking example can serve as the driver packages.

In General, if to describe a program system software and more, is to begin to dwell on what they are, what functions they have.

Classification of system software and their functions

If we talk about the separation of software programs into classes according to their purpose, there are several basic groups. So, the system programs may include (in different versions of the classification): managers (residential and transit), manufacturing, basic and service.

Considering the functions of the system in General terms, without going into details of how they work, note that the control application is designed to use internal data to the OS and are responsible for the correct functioning of all computational processes. Machining programs provide communication between “operating system” and components installed (the most striking example - DirectX and driver sets). Basic programs – this is the minimum set required for operation of the system as a whole. Finally, service programs – is a diagnostic tool and enhance the performance of modern computer systems.

Windows System software

As for the Microsoft Windows operating systems, they all have a minimal set of applications installed in the computer system during the installation itself “operating system”.

If someone does not know themselves system programs, for example, in Windows 7 can be found in the “start” under “Programs / accessories / system tools”. In addition, there are two directories: “Administration” and “Service”. All three are directories and system utilities designed to monitor, optimize, protect or restore system, backup, etc. to describe them in Detail makes no sense, since usually not every user is drawn to them, preferring third-party apps. And this, I must say, there is a certain sense.

Deleting system programs Windows computer are not provided. The trick in Android OS, when in the presence of root-rights you can delete any system component until the "OSes" are not here. In principle, you can only uninstall apps installed by the user. In General, this is correct, because after such intervention, the whole system will simply cease to function.

Third Party software

Windows is considered the world's almost the most popular “operating system” in the number of users. However, in terms of vulnerabilities and a minimal set of functions, a huge number of defects and the lack, it would seem, simply the mandatory tools, it is, unfortunately, all too ahead. Probably for this reason, many developers of system software and create a huge number of utilities and software packages for that OS. Judge for yourself, because by and large the same programs for the system administrator in Windows are virtually absent.

But it also has its pitfalls. The fact that very often causes a system error "Run program is impossible (for such a reason-or no reason at all)”. This is due only to the fact that each tool can be installed in the system, for example, due to the incompatibility of the system requirements, different architecture, OS and application installations (error: "... not a valid Win32 application"), lack of drivers, etc.

Nevertheless, The basic system programs from third party developers presented is much broader than that of Microsoft. Consider a base application which is a must have every user of a computer system.

Antivirus software

Typically, after a first install or reinstalling the system from scratch, the first thing you need to install antivirus software package that could protect the system at all levels, including tracking of external threats, such as viruses in the computer memory, network or the Internet, etc.

What will this program, the user decides for himself. Now the choice is wide enough. Among the most popular anti-virus packages you can select the most well-known: almost all software products «Kaspersky Lab», the application of the Corporation Eset (NOD Smart Security), products such as Dr. Web, Norton Antivirus, AVG, Avira, Panda, Avast, etc.

Naturally, each of these packages has its advantages and disadvantages. In addition, some apps are distributed for free and not have restrictions on use, others you have to pay, and very often a round sum. However, everyone decides for himself what to use.

Archives

The Second component of binding, which must be installed on any system is a program for working with archives. Most often this type of application is integrated into Windows shell (quick commands are in context menu).

The best archivers, according to many users and users, it is possible to call WinRAR, WinZIP, 7-Zip, and many others. Why the need to install them? Yes, simply because compressed archives are now used everywhere. Even download large files from the Internet is in the form of archival data.

Programs to test the system and its components

Of Course, one would be limited to using only native Windows tools, but they give not the full information about the state of the system and its components. For example, if you enter the menu “My computer” / “Properties”, there you can see only the basic parameters of the “iron” and set “operating system”.

The same applies to DirectX. Although the information is more detailed, it is still far from what can be squeezed out of third-party applications. The only thing that is nice – DirectX allows special tests of some devices Plug&Play.

To Determine the system load or to get more information on the tabs menu “Configuration” called “msconfig”, use “system Information" in control Panel, or, finally, to use Ctrl + Alt + Del calling the task Manager (for monitoring running processes, CPU usage and RAM, etc.).

Much easier to use utilities of type Everest or something that will not only give a detailed characteristics of the installed equipment, but also can track the change of its physical parameters in real-time.

In addition, this may also include some programs for the system administrator whose task is to monitor the network status, correct functioning and prevent threats to or unauthorized access to a network of computer terminals and servers.

Optimizers

System programs to optimize is very important. Probably don't need to explain to anyone. Over time, the system starts to slow down in most cases due to accumulated rubbish or computer debris. In addition, the reason may be the presence of a large amount of fragmented data. Of course, you can use standard tools Windows-type cleaning or disk defragmentation, but, as practice shows, they are less effective than software products of third-party developers.

With the registry and worse. In Windows there is no tool to clean it. And manually delete or adjust the incorrect or obsolete entries and keys-it is absolutely ungrateful. So it is possible the whole system “put”.

As a rule, almost all utilities of this type are versatile packages that are presented to...
