网络电脑（Network Computer）是指几乎只通过网络（包括以太网的局域网或互联网）完成操作的轻量级计算机。它有自己的中央处理器和随机存储记忆体，没有如硬盘等的辅助存储器（Secondary Storage），通过计算机网络启动，并在本地运行应用进程。这类网路计算机和计算机终端不同，它不是应用进程服务器的一个客户端。

20世纪90年代，部分评论员和业界巨擎如Larry Ellison和甲骨文公司（Oracle Corporation）预言，网路计算机将在不远的将来取代台式机，而用户将通过网络运行应用进程，而无需把应用进程拷贝至本机。

The Network Computer (or NC) was a diskless desktop computer device made by Oracle Corporation from approximately 1996 to 2000. The devices were designed and manufactured by an alliance, which included Sun Microsystems, IBM, and others. The devices were designed with minimum specifications, based on the Network Computer Reference Profile. The brand was also employed as a marketing term to try to popularize this design of computer within enterprise and among consumers.
