A special operating system installed on a file server, with portions loaded to the client machines. It enables the machines to communicate and share files.
Network service provider (NSP)
A high-level Internet service provider offering connections to ISPs. The NSP leases high-speed, high-capacity lines to handle the communication traffic from hundreds of ISPs.
A collection of artificial neurons loosely designed to mimic the way the human brain operates. Especially useful for tasks that involve pattern recognition.
