Glossary AD Active Directory. Baseband Systems that put digital signals from the data communications device on to the cable without modulation; only one data signal can be carried. BIOS basic input/output system. Broadband Systems that have multiple independent frequency channels, usually achieved by Frequency Division Multiplexing. Browser Server Systems which maintain lists of Servers and the services they offer. CIFS Common Internet File System - the latest version of SMB DMP NetBIOS Diagnostic and Monitoring Protocol Domain A logical grouping of systems within an SMB / CIFS network used for management and authentication. Within Microsoft networks a domain might be an NT 4.0 domain or Windows 2000 domain. DSAP Destination Service Access Point Group Name NetBIOS (and SMB / CIFS) name shared by a number of systems on the network. Hybrid node Hybrid nodes ("H" nodes") are nodes on a network using NetBIOS over TCP/IP. Hybrid nodes are not defined in RFC 1001 and have not been standardized; these are mixed nodes (similar to "M" nodes) but function broadly in the opposite manner to "M" nodes. "H" nodes function as a "Point to Point" node first and then as a "Broadcast" node.
