24. A UNIX or Linux file system information storage area that holds all details about a file. This information includes the size - the access rights - the date and time of creation - and a pointer to the actual contents of the file.






25. In general - a listing that organizes resources and correlates them with their properties. In the context of NOSs - a method for organizing and managing objects.






26. An area covered by a wireless access point that provides visitors with wireless services - including Internet access.






27. A group of users - servers - and other resources that share account and security policies through a Windows Server 2003 or Server 2008 NOS.






28. A connection from an Earth-based transmitter to an orbiting satellite.






29. A standard protocol for accessing network directories.






30. A user account that has unlimited privileges to resources and objects managed by a server or domain.






31. 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






32. A type of phone that includes a screen and can decode compressed video and interpret transport and signaling protocols necessary for conducting videoconference sessions.






33. In the DiffServ QoS technique - a forwarding specification that allows routers to assign data streams one of several prioritization levels.






34. An access point that provides routing functions and is used as a gateway.






35. An operating system's method of organizing - managing - and accessing its files through logical structures and software routines.






36. The preferred Active Directory naming convention for objects when used in informal situations. This name looks like a familiar Internet address - including the positioning of the domain name after the @ sign.






37. An internal or externally attached adapter that converts analog telephone signals into packet-switched voice signals and vice-versa.






38. In 802.11 wireless networking - a type of frame issued by a station during active scanning to find nearby access points.






39. A consortium of companies - including Sony Ericsson - Intel - Nokia - Toshiba - and IBM - that formally banded together in 1998 to refine and standardize Bluetooth technology.






40. In IEEE terminology - a group of stations that share an access point.






41. A Session layer call signaling protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for call or videoconference setup between nodes on a VoIP or video-over-IP network - indicating node status - requesting addit






42. The brand of computer central processing unit invented by Apple Computer - IBM - and Motorola - Inc. - and used in IBM servers.






43. Any implementation of UNIX for which the source code is either unavailable or available only by purchasing a licensed copy from Novell (costing as much as millions of dollars).

47. A highly privileged user ID that has all rights to create - delete - modify - move - read - write - or execute files on a UNIX or Linux system.






48. A service in which video signals are compressed and delivered over the Internet in a continuous stream so that a user can watch and listen even before all the data has been transmitted.






49. 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.
