What Is VNC and How Does It Differ From A VPN?

I know you are quite familiar with what a VPN (Virtual Private Network) is and also what a VNC (Virtual Network Computer) is, however, both terms mean different things.

It is important to note that, VNC provides a remote control for a computer at some other location permitting users to operate the same computer as if they are sitting in front of the computer. Resources that are available on the remote computer, such as printers and network drives, can be accessed. One interesting fact is that the remote site can see what the remote user is doing and even relate with them.

On the other hand, a Virtual Private Network (VPN) just simply help you get connected to a remote network, but one thing it does not do is that it does not give you a desktop to use. Rather, you can use your own desktop to get quick entree to the resources that exist in the network, such as printers, network drives, and internet connection. Also, a VPN helps your online activities to be anonymous, thus, it also helps to change your IP address for you to get connected to any place or site anywhere in the world.

One thought on what is VNC and how it does differ from a VPN; this is due to the fact that the two networks are that, your computer joins a remote network when you use a VPN, whereas you can only view and use a remote computer when using a VNC.  It is necessary also to note that VNC was developed by an AT&T research team.

In this article, we will take a detailed on what is VNC and some other features that have to do with VPN. Let’s jump right in!

Virtual Network Computer or Computing

There are two ways in which you can use VNC:

  • To remotely access a work desktop from a particular location
  • To permit technical specialists to take control of your computer to support you in activities

What Are the Uses of VNC?

Remote workers

You may be asking yourself what is VNC and why is it very important? Well, as we have said earlier, VNC provides a remote control for a computer. Talking about the uses of VNC, have you ever wondered how workers of some companies assess the company’s desktop using a VNC? But this is done with the permission of the company.  For employees operating their desktops in the office is due to the fact that VNC provides some security because employees do not need to take company documents and emails with them in order to respond to after-hour issues. Instead, they can always just log into their work computer and the company data don’t have to leave the office in any way.

Business Continuity Processes (BCP)

Lots of accidents and disasters occur which puts us in situations that make us to not have physical access to a workplace, but having VNC access to work computers takes away the necessity to have that physical access to a computer during these times.

It is often common these days that most of all company’s networking infrastructures are located offsite and most times, it is really far away to access. When access to servers is remote, it is possible to lose access to a server via the normal means. Most cloud providers offer the ability to launch a temporary VNC instance to allow a remote access to the console of those cases.

Remote technical support

The only answer for remote technical support is VNC.it is important to note that VNC permits a remote technician to control your desktop as if they were onsite, and it requires almost no knowledge of the person in need of the support. Lots of organizations make use of VNC in their internal IT departments to help with routine tasks. Also, there are lots of third-party companies that also make use of VNC too. VNC is a very useful for support because the person in need of the support can watch what is happening and even chat with the technician.

What are the advantages of using VNC?

The use of VNC is highly important and it is a big program that has been developed since the 1990s. It operates on a very simple protocol called the Remote Framebuffer Protocol, in this article, we will talk on that very soon.

Also, VNC is an important platform and autonomous due to the fact that the mechanism used to transport desktop images and keyboard presses back forth exists under the operating system. If you are wondering if VNC has a client for every device, yes there is. VNC client is compactable with any device including mobile phones.

What are the disadvantages of using VNC?

There are lots of disadvantages to using VNC due to the way it works. It is important to know that VNC makes use of bandwidth to transfer desktop files or images to the client. If there is a situation where there is a low bandwidth, this may cause a big issue. However, lots of VNC clients allow various users to be exact on the location of both the resolution of the remote screen and also the depth of use. You need to know that a low resolution or grayscale screen can be transferred fairly quickly and work well when there are low bandwidth situations.

VNC exist in some forms, but the basic form of it uses the raw encoding method. If there are cases of disparities between the client and the server and they do not share any advanced encoding methods, then the raw screen will be sent from the server to the client pixel-by-pixel in a certain manner. Recent methods try to decrease this situation just by sending little pixels; this may work very well for small mouse cursor changes, but it depends on when the entire screen changes such as when reading a document or a web page.

Another potential disadvantage of VNC is that, since it only uses a remote desktop, only applications available on the desktop can be used. Maybe you are the type of person that loves to use an application that you have on your PC on the remote computer, the only way to achieve that is to install that same application that you have on your remote computer, but this depends on your use-case of using VNC, because it might be a problem.

Another issue has to do with performance. You need to know that your program is only as fast as the slowest available internet connection. You need to know that if your internet connection is very slow, you may run the risk of not being connected properly on your large client. You also need to know that performance issue will also tend to increase as you use real-time programs and interactive applications.

Virtual Private Network

What Is VNC and How Does It Differ From A VPN?

Now that you know “what is VNC?” we also need to talk about VPN too. A VPN has just one single purpose, which is: to create a private network between your computer and some remote network just by utilizing the public internet as the carrier.

What are the common uses of a VPN?

When you have gotten a reliable connection, the uses of that private network are unlimited. However, VPN generally allow workers to access a company’s network resources remotely and use the internet connection at the remote site as a proxy to the public internet

Advantages of using VPN

If you are concerned about privacy then, getting a VPN like TorGuard is ideal. This is due to the fact that TorGuard encrypts the traffic between your computer and the VPN entry point. With a VPN, you can use your local application against the remote network. For instance, a remote network may allow VNC connections to the desktops on it, but it will not expose those VNC servers. In this case, connection through a VPN to the remote network first, and then using your local VNC client to access the desktops is a more secure way to allow it.

No doubt, you have known the advantages of VPN and what is VNC.  You need to know that VNC clients have been so heavily modified which can make it necessary to use the specific VNC client with its server.
