What is Virtual Network Computing (VNC)?

The other day my wife was surfing on a website named TIAS, because my youngest son Jake needed a new pair of soccer cleats. All of a sudden, the computer crashed, and she could not proceed.

I was not in town because I hade an important business meeting the next day. She called me that there was a problem she could not fix. So I grabbed my laptop and connected via a so-called VNC client so that I could fix the issue from out of my hotel room.

This little incident was the inspiration why I created this website in the first place. I hope it helps people with similar issues from all around the world. So what exactly is Virtual Network Computing?

Before we go into the depths of the topic, let us first know what is Virtual Network Computing (VNC)?

VNC (virtual network computing) is a more recent kind of technology that allows remote desktop sharing, which means a person can access the data on his computer on another desktop. It can be said
to be a type of remote access on computer networks. This allows a user to see his/her own computer’s visual desktop display on another computer. This helps control and manipulate that computer over a network connection.

VNC is not only used in home computer networks to access a computer from different parts of the house, but it is also used by the IT departments of big multinational companies to troubleshoot any problem without having to waste any time remotely. Whatever be its scale of operation, VNC is indeed one of the most useful technologies of recent times.

What Are VNC Applications?

VNC applications are applications that enable you to install VNC technology on your desktop. VNC apps were first introduced in the 1990s. The first successful VNC application was Real VNC. Due to massive technological developments after that, many VNC applications have cropped up in the market — the best ones being:

Ultra VNC and Tight VNC. Nowadays, VNC applications are available for every kind of operating system; whether it is Windows or Linux, you can get a VNC application for everything. If you do your research, you will also come across many efficient VNC applications that are not only efficient but are also free and easily downloadable.

How Does VNC Work?

VNC is based on a server/client model. A client-server model is a network model that easily enables interaction with the client and the server. VNC uses a unique network protocol known as the remote frame buffer (RFB). Individuals who use VNC or VNC clients share user input like mouse movements touches with the server, clicks, and keystrokes.

VNC servers capture the data and the functioning of the local computer and share it back to the client. On the server, connections over RFB go to TCP port 5900.

VNC is indeed an easy way to be able to access your data remotely. However, sometimes VNC may be very slow and inefficient, given there is a data overload or network interference. However, the good thing about technology is that there are many alternatives to perform a single function. Hence, as you guessed it, there are also many alternatives to VNC.

Various multinational tech giants have contributed recently to develop their VNC apps. Microsoft, Chrome, and Apple have developed Windows Remote Desktop (WRD), Chrome Remote Desktop, and Apple Remote Desktop (ARD), respectively.

This is all about the question what is Virtual Network Computing (VNC)? VNC allows a user to gain access to his/her data over another computer and enables data sharing. A VNC user should be immensely careful with VNC networking and make sure that all his data that is shared is safe and protected.
