9. A client or server operating system originally developed by researchers at AT&T Bell Laboratories in 1969.






10. A logical representation of multiple - hierarchical levels in a directory.






11. A protocol used between media gateway controllers and media gateways. It is poised to replace MGCP on modern converged networks - as it supports a broader range of network technologies - including ATM. Also known as H.248.






12. The real-time reception and transmission of images and audio among two or more locations.






13. In LDAP naming conventions - the name of any one of the domains to which an object belongs.






14. The core of a UNIX or Linux system. This part of the operating system is loaded and run when you turn on your computer. It mediates between user programs and the computer hardware.






15. A licensing mode that allows a fixed quantity of clients to use one software package simultaneously.






16. A file system developed by Microsoft and used with its Windows NT - Windows 2000 Server - Windows Server 2003 - and Windows 2008 operating systems.

19. The exchange of information between the components of a network or system for the purposes of establishing - monitoring - or releasing connections as well as controlling system operations.






20. A file on the hard drive that is used for virtual memory.






21. The characteristic of wireless signals that follow a number of different paths to their destination (for example - because of reflection - diffraction - and scattering).






22. A cost-savings benefit that results from organizations completing long-distance telephone calls over their packet-switched networks - thus bypassing tolls charged by common carriers on comparable PSTN calls.






23. A special identifier shared by BSSs that belong to the same ESS.






24. A GUI tool provided with Windows Server 2008 that enables network administrators to manage server roles - features - resources - and users from a single interface.






25. The centralized management of multiple types of network-based communications - such as voice - video - fax - and messaging services.

27. A service that uses the ATM network access method (and ATM cells) to transmit voice signals over a network.






28. An IEEE standard for wireless MANs. Its networks may use frequencies between 2 and 66 GHz. Their antennas may operate in a line-of-sight or non-line-of-sight manner and cover 50 kilometers (or approximately 30 miles). Its connections can achieve a ma






29. In the context of 802.11n wireless networking - the ability for access points to issue multiple signals to stations - thereby multiplying the signal's strength and increasing their range and data-carrying capacity.






30. 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.






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






32. A type of satellite that orbits the Earth with an altitude between 100 and 900 miles - closer to the Earth's poles than the orbits of either GEO or MEO satellites.






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






34. The software that sits between the client and server in a 3-tier architecture.






35. The action of associating a disk - directory - or device with a drive letter.






36. A type of trust relationship in which two domains that belong to different NOS directory trees are configured to trust each other.






37. A group of hierarchically arranged domains that share a common namespace in the Windows Server 2003 or Server 2008 Active Directory.






38. In the context of wireless signal propagation - the phenomenon that occurs when an electromagnetic wave encounters an obstruction and splits into secondary waves. The secondary waves continue to propagate in the direction in which they were split. Th






39. In Windows Server 2003 or Server 2008 networking - the single domain from which child domains branch out in a domain tree.






40. An area of a computer's hard drive that is logically defined and acts as a separate disk drive.






41. An ITU standard that describes an architecture and a suite of protocols for establishing and managing multimedia services sessions on a packet-switched network.
