22. A device used on wireless LANs that transmits and receives wireless signals to and from multiple nodes and retransmits them to the rest of the network segment. Those can connect a group of nodes with a network or two networks with each other. They ma






23. The diffusion of a wireless signal that results from hitting an object that has smaller dimensions compared to the signal's wavelength.

31. A domain established within another domain in a Windows Server 2003 or Server 2008 domain tree.






32. A group of access points and associated stations (or basic service sets) connected to the same LAN.






33. On a SIP network - a server that maintains a database containing information about the locations (network addresses) of each user agent in its domain. When a user agent joins a SIP network - it transmits its location information to the SIP registrar






34. On a SIP network - a server that accepts and responds to requests from user agents and SIP proxy servers for location information on recipients that belong to external domains.






35. A client/server environment that uses middleware to translate requests between the client and server.






36. A pictorial representation of computer functions and elements that - in the case of NOSs - enables administrators to more easily manage files - users - groups - security - printers - and other issues.
