Advantages of Enabling VNC Server on Ubuntu

1. Remote Access

Enabling VNC server on Ubuntu allows you to access your machine remotely from any device with VNC client software installed. This can be useful if you need to access your Ubuntu machine from another location.

2. Easy Collaboration

VNC server allows multiple users to access the same machine simultaneously, making it a useful tool for collaboration. You can use it for remote support, pair programming, or even for a remote team’s virtual stand-up meetings.

3. Secure Access

VNC server connection can be encrypted, meaning that your data is secure while accessing your Ubuntu machine remotely. This ensures that only authorized users can access your system, making it a more secure option than other remote access methods.

Disadvantages of Enabling VNC Server on Ubuntu
