Virtual Network Computing:
VNC Remote Assistance

Today: October 28, 2021

Virtual Network Computing or VNC remote assistance is a platform-independent system that allows a computer to view, access and control another computer remotely. This system is extensively used by people who remotely provide technical support. With VNC remote assistance, they could provide assistance to any computer around the globe through the internet. Another use for Virtual Network Computing is when a person, while he/she is at home (or anywhere for that matter), wants to view, access or control his own computer at his office; or vice versa.

Since the original virtual network computing system was made open source (under the GNU General Public License), several versions, some commercial some remaining free and open source, have come out. Some of these VNC remote assistance offshoots have become more efficient in terms of bandwidth management, improved security, and better speed of execution.

Virtual Network Computing was invented by Tristan Richarson, together with a team of network systems experts at the Olivetti & Oracle Research Lab. The Lab was acquired later by AT&T, about 3 years prior to the lab's closure.

Richardson, together with some of these original team members (Andy Harter, Quentin Staffor-Fraser, James Weatherall, Ken Wood, Andy Hooper, Charles McLachlan, Paul Webster) continued to work on VNC remote assistance, which they re-christened as RealVNC after Olivetti & Oracle Research Lab's closure in 2002.
