Network Computer Reference Profile (NC reference profle, NCRP) was a specification for a network computer put forward by Oracle Corporation, endorsed by Sun Microsystems, IBM, Apple Computer, and Netscape, and finalized in 1996. The first version of this specification was known as the NC1 Reference Profile. Although this initial NC standard was intended to promote the diskless workstation model of computing, it did not preclude computers with additional features, such as the ability to operate either as a diskless workstation or a conventional fat client. Thus, an ordinary PC having all the required features, could technically be classified as a Network Computer; indeed, Sun noted that contemporary PCs did indeed meet the NC reference requirements.
