Network Computing Devices
Network Computing Devices is a company founded by Judith Estrin and William Carrico in the late 1980's to produce a new class of products now known as a "thin client". At that time these devices were known as network terminals or X Terminals. The products were some of the earliest examples of a thin client and providing remote access to data in something other than ASCII as was common with traditional terminals of the time.
The X Protocol provided a way to show high resolution images of data and graphics over a network connection. Network Computing Devices (NCD) supported a range of network protocols including TCP/IP, Token-Ring, DecNet and others.
