Remote desktop access has become an integral part of modern work setups, enabling users to connect to and control computers or servers from remote locations. Among the various tools available for this purpose, VNC (Virtual Network Computing) server software plays a significant role. In this article, we'll delve into what is VNC server, how it works, and its uses, and then we’ll compare some of the best VNC server software options.


What is VNC Server?

VNC server is a software application that allows users to access and control a computer or server from a different location. It operates on a client-server model, where the server component is installed on the remote machine, and a VNC viewer, or client, is installed on the device used to control the remote computer.

VNC Server is like a magic window that lets you peek into another computer from far away. It's a special kind of software that you install on a computer you want to control from somewhere else.

For those of you still asking what is VNC server, imagine you're at home and you need something from your work computer. Instead of rushing to the office, you can use VNC Server to see what's on your work computer right from your home computer.


How Does VNC Server Work?

VNC server works by transmitting the desktop environment of the remote machine over the network to the local device running the VNC viewer. To learn what is VNC server configuration exactly, you should know it works like this:

  1. Capture and Convert: VNC Server captures the host computer's screen in real time and converts it into data packets.

  2. Transmission: These packets are sent securely over the network to a device running VNC Viewer.

  3. Display: VNC Viewer decodes and displays the data on its screen, showing exactly what's on the host computer.

  4. Interact: Users can interact with the host computer via VNC Viewer, moving the cursor, typing, and clicking as if they were there.

  5. Feedback: Any actions on VNC Viewer are sent back to VNC Server, creating a seamless loop where user inputs are reflected on the host computer's screen.

What is the Difference Between VNC Viewer and Server?

VNC Viewer and VNC Server are essential components of the Virtual Network Computing (VNC) system, but they serve different purposes. Now that you know what is VNC server in Linux, let’s compare the 2.

As we said earlier, VNC Server is the software installed on the computer or device that you want to access remotely. It acts as the host, transmitting the desktop environment of that computer over the network to another device.

On the other hand, VNC Viewer is the software installed on the device that you're using to remotely access and control the host computer. It acts as the best VNC client, receiving the transmitted desktop environment from the VNC Server and displaying it to the user. With VNC Viewer, users can interact with the remote computer as if they were physically present in front of it, moving the mouse, typing, and performing other actions.


What is VNC Server Used For?

You know what is VNC server Windows 10 so far. Now it’s time to see what is it used for. VNC Server serves as a versatile tool in remote computing, and offers a range of practical applications:

Whether working on group projects, conducting training sessions, or sharing information, users can collaborate effectively regardless of their physical location, enhancing productivity and teamwork.

Remote Work:

In today's flexible work environments, VNC Server plays a crucial role in enabling remote work scenarios. Individuals working from home or remote locations can securely access their office computers using VNC Server, ensuring continuity of work tasks, access to essential resources, and seamless communication with colleagues.



When it comes to remote desktop solutions, VNC (Virtual Network Computing) and RDP (Remote Desktop Protocol) are two commonly used options, each with its own set of features and functionalities. While they share similarities in enabling users to access and control remote computers, understanding their differences is crucial in selecting the most suitable option for specific needs.

You know what is VNC server address, so let’s get down to the comparison:


  • Both VNC and RDP allow users to access and control remote computers.

  • They require software on both the user's computer and the remote computer.

  • They use direct communication between the user's computer and the remote computer.


  • VNC works across different operating systems, while RDP is mostly for Windows.

  • RDP is often faster than VNC.

  • VNC connects directly to the remote computer, while RDP connects to a shared server.

  • RDP may have limitations in compatibility with various devices compared to VNC.
