What is an application? The application is in VKontakte. Apps for iPhone

Many users of computer and mobile systems often face the question: "What is an application?" Not everyone will imagine what it is. The thing is that sometimes, by removing 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 do not know how to start the program again.

What is an application: general concepts

In general terms, it can be said 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 that, referring to, say, the accompanying dynamic libraries, databases or something else, launches the application as such, by downloading to the specified device the main interface of the program and the modules necessary for its Correct operation.

If you take computer systems, such files usually have the extension .exe (Executive File - executable file). Previously, in DOS-type systems, you could encounter executable files such as .bat, installation files for .inf drivers, and so on.

It is believed that the usual "ex-file" as a separate application is extremely rare. It should be attached to all sorts of configuration files or databases, which it refers to during the start of a process. Even in portable (Portable) versions of programs, in most cases there are companion components.

Computer Applications

Install an application for a computer or for a mobile device, usually does not work. In computer systems, there is usually an "Install Shield" (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. Usually these are additional panels that are integrated into Internet browsers, search engines or software products that require promotion on the market.

Programs for mobile devices

In terms of mobile OS such as Android, iOS, BlackBerry and many others, the installation process is fundamentally hidden from the user's eyes. He watches only the descriptive process: they say, such and such an application is currently being downloaded or installed.

Note that in this case (unlike computer systems with the location of the installation), the installation takes place at the place specified by the mobile operating system itself. So to track where exactly the new program will be installed, it is almost impossible for an ordinary user.

"VKontakte" application: what is this?

Probably, every registered user in one of the most popular social networks "VKontakte" certainly would like to have the possibility of constant access to his data, contacts, correspondence, listening to music, watching videos and yet God knows what. To do this, and created client programs for computer systems, applications for the iPhone and iPad, for Android systems, etc., etc., etc. As a rule, they all have the same or very similar interface.

Especially it is worth noting that the general package implies only communication on the social network, viewing photos, exchanging links or messages, posting posts and some other things.

Proceeding from the fact that the standard package is not complete, for the social network "VKontakte" special applets are being released, for example, for downloading music (in the usual way you will not be able to save the track you like). The same goes for the video.

In addition, depending on the version of the complete package, it can also include a lot of various additions. That only there are free modules like "LoviVKontakte" for comfortable listening and downloading multimedia, VKontakte DJ for creating and managing audio multisessions, VKontakte Unlock (means for unlocking the account), "VKontakte", which allows you to communicate without calling the page in an Internet browser, VKontakte Online (rather specific browser, as they say, "sharpened" specially for the social network), VKAudioSaver for downloading music or MuzVK for searching and downloading liked tracks with public or private access.

As is already clear, this list can be replenished more and more. Fortunately today, enthusiasts who create applications to work in this popular network, enough with his head. What is most interesting, many do not climb into the jungle of programming, but use the universal Java platform. Running an application of this type is possible even on devices without having an officially specified operating system (although it itself is in some form or another in the same usual mobile phone is still present).

Possible errors when running on a computer

Now you have to add a little tar to the barrel of honey. Most often, an error when running an application on a computer can be reduced to several basic aspects. First of all, this is due to the fact that the program itself or the applet is simply incompatible with the "operating system". This mainly applies to Win32 applications in a 64-bit OS.

Although support for 32-bit systems is provided, most of them are considered obsolete. Exactly the same situation is observed when trying to run a 64-bit application in Win32 systems.

Compatibility with mobile operating systems

As for mobile gadgets based on iOS, Android or something else, here very often the problem is reduced only 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 the version of the program that is designed for a certain OS. A simple example: if the VKontakte application, which is, say, on the Play Market, is designed for installation only in Android 4.4, on the "deuce" of version 2.3, you can not even try to install it (it still does not work).

The same parallel can be made with mobile systems (more precisely, with modifications of smartphones) from Apple.

The developers and specialists of this company are related to the system requirements in the field of installing applications, applets and programs much more seriously than all the others. Due to this, by the way, an unprecedentedly high rating of their devices (that of stationary computers, that of mobile devices) is maintained. In this case, applications for the iPhone of any generation are not an exception.

Features of VKontakte applications

If we consider the features of applets of this type, for starters, every user who is going to download one or another software product from the Internet should take care of understanding what such an application is all about. After all, today (and it's not a secret for anyone), any computer (even a laptop or a friend's smartphone) can become a "source of infection". By launching the link in the same VKontakte network, you can easily grab a virus or malicious code. Unfortunately, according to statistics, it is this network that contains the greatest number of online viruses that can spontaneously copy and distribute between computer terminals or mobile devices.

The result

So, with an answer to the question, what is an application, we have already sorted out a little. In principle, if we consider specific programs and add-ons like "VKontakte" with a common name, it should be noted that today the software products themselves can be found very much, as they say, for all occasions, even the most unforeseen. Another thing - how to relate to the safety of your own computer or mobile device. Agree, no one wants to grab a virus that will lead the whole system to crash. Here, of course, you need to be very careful, and before downloading content, scan files, folders, archives or the same antivirus links for potential threats.
