The article describes what a program for accessing a remote computer is, why it is needed, and in particular, one of them called TeamViewer is considered.
Remote access

With the development of computer technology and the increase in their availability, the need gradually arose for specialists who would serve them. Of course, home and personal computers differ from their huge clumsy predecessors precisely in simplicity and convenience, however, breakdowns and errors sometimes occur that are extremely difficult or impossible for the average user to cope with. In addition, the level of knowledge is different for everyone.
Unlike other areas of activity, the personal presence of the master to solve the problem is not necessary (if it affects only the software part). This is how the function, and later the program for accessing a remote computer, arose. So what does it do, when is it used, and when is it useless?
Definition
In fact, the role of such programs is to receive a fullcontrol of the desired computer. And, by the way, they are used not only to solve problems, but also in a number of other cases, for example, for control, ease of managing various systems, etc.
It looks like this: a program for accessing a remote computer captures the image of someone else's "desktop" and control over input-output devices, and then broadcasts all this via a local network or the Internet to the end user. The possibilities of such technology are not much inferior to real control. Of course, when it comes only to the software part, unfortunately, it is still impossible to physically influence the equipment remotely.
Application
Most often, such programs are used in large enterprises, where the system administrator needs to control a large number of computers, and physically bypass each one for a long time and is not practical. In practice, usually everything is limited to correcting the mistakes of illiterate users, or performing actions that require administrator rights.
In addition, a program for accessing a remote computer is also needed as a way to control and manage a server, database or other device that is far away, or requires frequent, but little intervention in operation or settings.
TeamViewer

Gradually, ordinary users also fell in love with such programs, who needed to quickly and easily check someone else's computer or do something with its system. In recent years, hugea program called TeamViewer gained popularity.

It's completely free (for non-commercial use) and the latest versions don't even require installation.
