Protocol for VNC NX

In VNC NX systems several computers share the same processor.

VNC stands for "Virtual Network Computing." It was invented by Olivetti and then taken over by the RealVNC company. The VNC system is a "thin client" protocol. NX is another thin client system created by an Italian company called "NoMachine." VNC has become a generalized term for thin client systems. NoMachine never refers to its NX system as VNC NX, although others do.

Features

In a VNC system (thin client) the client is a terminal without any Central Processing Unit . The user accesses a centralized processor, without being aware that the computing power is not directly attached to the monitor, keyboard and mouse. Rather than being based directly on VNC, NX is based on the X Windows thin client system.

Function

X Windows is a straightforward thin client or VNC system. NX adds to the X Windows system by incorporating Secure Shell encryption and compresses data in transmission to speed up response times.

Future

The data compression function of NX was the factor that made it popular for those with slow dial-up connections. The advent of broadband and high-speed Internet reduces the popularity of the protocol.
