The rate at which data is transmitted across a network connection. Bandwidth is usually measured in "bits per second" and broadband connections range from 512 kilobits per second up to 20 megabits per second and beyond. The bandwidth required by VNC varies greatly depending on the nature of the activity on the VNC Server. Generally a 1 megabit (or 1024 kilobit) per second connection will provide a good level of responsiveness and control.
