Getting to Know about VNC

There are different ways to control computers remotely. Here, we will tell you about a system that allows you to do so. The name of the system is Virtual Network Computing or VNC for short. Below we explain what it is, how it works, features, pros and cons, security, and five software for remote control using the system.


What Is It?

To put it simply, it is a system upon which you can control a computer using another computer remotely. The system not only displays the controlled computer, but also allows the user to input command using touch, mouse, and keyboard.

How Does It Work?

The system works in a client/server model. It uses a specialized network protocol known as a remote frame buffer. Thanks to this specialized network protocol, the clients share the user’s input, be it touches, mouse movements, keystrokes, or click, with the server.


  • Works on a client and server model.
  • Compatible with any operating system as it is platform-independent.
  • Secure, especially if encryption is used.
  • Connects computers but at the same time separates the environments.

Pros and Cons


  • It operates on a robust yet simple protocol.
  • The system is platform-independent as it works “under” the operating system although the connection between client and server is required.


  • It uses a lot of bandwidth, which can be an issue if the bandwidth is low.
  • Thanks to the separation of environments, users can only use the applications that are available on the computer.


VNC has been present since the 1990s. This is the availably of security varies widely. The base remote frame buffer does encrypt passwords but these passwords can be sniffed from the network. That being said, nowadays many virtual network computing-based software add encryptions, thus making the entire connection encrypted.

Although the system allows for remote connection and control, it separates the environments of the computers. Only inputs like screen data, mouse clicks, and keyboard are transferred across. This, in a way, added a layer of security, preventing viruses or worms from moving from a computer to another.

Best VNC Software for Windows OS

1. TightVNC Viewer

This one is worth a look if you want remote desktop software with a solid history. It allows virtual network computing and JPEG compression, which conserves bandwidth and reduces render lag.

2. VNC Viewer Plus

This software offers more than just a virtual networking computing connection. It also allows the user to communicate with Intel hardware. Essentially, giving the user complete control over a PC.

3. UltraVNC

This one is ideal if you want software that consolidates all display options. It has extra features such as connection quality setting options and a chat feature.

4. TigerVNC

A solid option if you want a more modern interface and improved security.

5. SmartCode Web VNC Viewer

Perfect for users who want a simple tool for remote desktop access but don’t want to use dedicated software for virtual network computing.


That is VNC in brief. In short, it is a system that allows you to control a computer or more remotely. For this to be possible, the computers to control and control from must be connected with the system. If you are interested in using this system, the five software we listed above is worth a look.
