The AppleShare protocol is a communications protocol from Apple Computer that allows client applications in a computer to exchange files with and request services from server programs in a computer network. AppleShare can be used over the Internet on top of the TCP/IP protocol, or on top of other network protocols such as Internetwork Packet Exchange and AppleTalk. Using the AppleShare protocol, a user can access files, applications, printers, and other resources on a remote server. It can communicate with any server program that is set up to receive an AppleShare client request.
All Macintosh and Mac OS clones include client and server AppleShare protocol support. Microsoft Windows NT Server and Novell NetWare both provide AppleShare server protocol support, although they currently only support AppleShare over AppleTalk. Third-party AppleShare client/server support is available for Microsoft Windows for Workgroups, Windows 95, and Windows NT, as well as for UNIX systems.
A given client and server may implement different sets of Appleshare protocol variations. The set of protocols to be used is negotiated before starting a session.
