Before we dive into the details of configuring TightVNC Server on Ubuntu, let’s first understand the basic concepts of VNC and its significance in the world of technology.
What is VNC?
Virtual Network Computing or VNC is a technology that allows users to access and control a remote computer over the internet. VNC works by transmitting the graphical user interface of the remote computer to the client computer, enabling users to control the remote computer as if they are sitting in front of it.
How does VNC work?
VNC works on a client-server architecture. The server is installed on the computer that needs remote access, and the client is installed on the computer that will access the server. When the client connects to the server, the server transmits the graphical user interface of the remote computer to the client. The client sends input commands back to the server, which the server executes on the remote computer.
Why use TightVNC Server on Ubuntu?
TightVNC Server is a popular choice for remote access applications on Ubuntu because of its simplicity, ease of use, and reliability. TightVNC Server is lightweight and can be installed on almost any computer, making it an excellent choice for both personal and enterprise applications.
