Liberate

(Liberate Technologies, San Mateo, CA) A software company that specialized in the information appliance field. Formerly Network Computer, Inc. (NCI), a spin-off from Oracle in 1996, it changed its name in 1999. The company initially promoted the NC Reference Profile specification, later turned over to The Open Group. Liberate provided client and server software for satellite, cable, telco, ISP and corporations to deliver thin computing services. In 2005 the company declared bankruptcy and sold its North American assets to Cox Communications and Comcast Corporation. See network computer.



network computer

(1) Any computer in the network.

(2) A platform for personal computers introduced in 1996 that never caught on. However, the concept was valid and has subsequently been embodied in Web-based applications. In 2011, Google introduced a 21st century replica of the network computer (see Chromebook).

The network computer (NC) was a "thin client" that downloaded all applications and data from the network and stored updated data back on the server. NCs were touted as "the" way to reduce costs due to centralized administration and lower-priced workstations. Its major proponents were Sun and Oracle, and Oracle subsidiary Network Computer Inc. licensed the specification for building compliant machines (see NCRP and Liberate).

Java-Based Machines
NCs ran stand-alone Java applications as well as Java applets from a browser. Several NCs were developed, running a compact operating system that was booted from the server along with the Java Virtual Machine (Java interpreter). Using Citrix software, NCs could also function like dumb terminals connected to a Windows NT or 2000 server.

What Happened?
Hyped as the death knell for Windows PCs, the price of PC hardware was dropping exponentially, and the cost difference between NCs and PCs quickly became negligible. In addition, Windows was heavily entrenched, and a new platform was not appealing to corporate IT managers. See thin client.




Not Making Inroads
After two years, the network computer was not making an impact; witness this 1998 column from the Philadelphia Inquirer. (Article headline courtesy of the Philadelphia Inquirer.)
