Too many users of computer and mobile systems often face the question: “What is an application?” Not everyone can imagine what it is. The fact is that sometimes, having removed a shortcut from the main screen of a mobile gadget or from the desktop of a computer or laptop, not to mention mobile devices, many simply don’t imagine how to start the program again.
What is an application: general concepts
In general terms, we can say that an application is not a single file, but sometimes a collection of several files combined into one software package. The application itself from the point of view of computer technology is an executable file, which, referring, say, to related dynamic libraries, databases, or something else, launches the application as such, loading the main program interface and modules necessary for it onto a specific device correct operation.
If you take computer systems, such files, as a rule, have the extension .exe (Executive File - executable file). Previously, on DOS-type systems, one could find executable files such as .bat, driver installation files .inf, etc.
It is believed that the usual "exe" file as a separate application is extremely rare. Various configuration files or databases must be attached to it, to which it refers during the start of a process. Even in portable versions of programs in most cases, there are related components.
Computer applications
Installing an application for a computer or for a mobile device, as a rule, is not difficult. In computer systems, there is usually a “Setup Wizard” (Install Shield, Install Wizard, etc.).
It is only necessary to follow its instructions, and sometimes to exclude some additional components for installation, which are offered by free programs. Typically, these are additional panels that integrate into Internet browsers, search engines or software products that require market promotion.
Mobile Software
In terms of mobile OSs such as Android, iOS, BlackBerry and many others, the installation process is fundamentally hidden from the user's eyes. He observes only a descriptive process: they say that such and such an application is currently downloading or installing.
Note, in this case (unlike computer systems with an indication of the installation location), the installation takes place at the location specified by the most mobile OS. So to track where exactly the new program will be installed, the average user is almost impossible.
Vkontakte application: what is it?
Probably, every registered user in one of the most popular social networks “VKontakte” would certainly want to be able to constantly access their data, contacts, correspondence, listen to music, watch videos and God knows what. For this, client programs were created for computer systems, applications for iPhone and iPad, for Android systems, etc., etc. As a rule, they all have the same or very similar interface.
It is especially worth paying attention to that the general package means only communication on a social network, viewing photos, exchanging links or messages, publishing posts and some other things.
Based on the fact that the standard package is not complete, specialized applets are being released for the VKontakte social network, for example, for downloading music (in the usual way, saving a favorite track will fail). The same goes for the video.
In addition, depending on the version of the full package, it may also include a lot of the most diverse additions. Why are there free modules like “LoviVKontakte” for comfortable listening and downloading multimedia, VKontakte DJ for creating and managing audio multisessions, VKontakte Unlock (means for unlocking an account), “VKontakte Agent” allowing you to communicate without calling a page in an Internet browser, VKontakte Online (a rather specific browser, as they say, “tailored” specifically for a social network), VKAudioSaver for downloading music or MuzVK for searching and downloading your favorite tracks with public or private access.
As already clear, this list can be replenished more and more. The benefit of today's enthusiasts creating applications for working on this popular network is enough. What is most interesting, many do not crawl into the jungle of programming, but use the universal Java platform. Launching this type of application is possible even on devices without the presence of an officially specified operating system (although it is still present in one form or another in the same ordinary mobile phone).
Possible errors when starting up on a computer
Now you have to add a little tar to the barrel of honey. Most often, an error when launching an application on a computer can come down to several main aspects. First of all, this is due to the fact that the program or applet itself is simply incompatible with the "OS". This mainly concerns Win32 applications in 64-bit OS.
Although support for 32-bit systems is provided, for the most part they are considered obsolete. The exact same situation is observed when trying to run a 64-bit application on Win32 systems.
Mobile Operating System Compatibility
As for mobile gadgets based on iOS, Android or something else, very often the problem boils down to the fact that the current version of the operating system or its update simply does not match the parameters of the application itself. As a rule, to solve this situation, it is worth looking for exactly that version of the program that is designed for a specific OS. A simple example: if the Vkontakte application, which is present, say, on the Play Market, is designed to be installed only in Android 4.4 OS, on the “deuce” type of version 2.3, you can even not install it (it still won’t work).
The same parallel can be drawn with mobile systems (more precisely, with modifications of smartphones) from Apple.
The developers and specialists of this company take the system requirements in the field of installing applications, applets and programs much more seriously than everyone else. Due to this, by the way, the unprecedentedly high rating of their devices is supported (both stationary computer and mobile). In this case, iPhone applications of any generation are no exception.
Features of VKontakte applications
If we consider the features of applets of this type, for starters, every user who is going to download a particular software product from the Internet should take care to understand what an application is in general. Indeed, today (and this is no secret to anyone) any computer (even a laptop or a friend’s smartphone) can become a “source of infection”. By launching a link on the same VKontakte network, you can easily grab a virus or malicious code. Unfortunately, according to statistics, this network contains the largest number of online viruses that can spontaneously copy and distribute between computer terminals or mobile devices.
Total
So, with the answer to the question, what is the application, we have already figured out a little. In principle, if we consider specific programs and add-ons such as VKontakte with a common name, it is worth noting that today there are a lot of software products themselves, as they say, for all occasions, even the most unforeseen ones. Another thing is how to relate to the security of your own computer or mobile device. You must admit that no one wants to capture the virus, which will lead the entire system to collapse. Here you definitely need to be very careful, and before downloading content, check the files, folders, archives or the same links with antivirus for potential threats.
