Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. An end node on a network; used most often in the context of wireless networks. transponder






2. Another term for the UNIX command interpreter.






3. Currently - the most popular version of WiMAX. IEEE improved the mobility and QoS characteristics of the technology - making it better suited to VoIP and mobile phone users.






4. A type of satellite that orbits the Earth roughly 6000 to 12 -000 miles above its surface - positioned between the equator and the poles. These satellites can cover a larger area of the Earth's surface than LEO satellites while using less power and c






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






6. A service in which television signals from broadcast or cable networks travel over packet-switched networks.






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






8. A computer that provides support for multiple H.323 terminals (for example - several workstations participating in a videoconference) and manages communication between them.






9. 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.






10. In IEEE terminology - the identifier for a BSS (basic service set).






11. A Session layer control protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for controlling a session between two nodes. For example - it ensures that the two nodes are communicating in the same format.






12. A standard protocol for accessing network directories.






13. The method for organizing and managing objects associated with the network in the Windows Server 2003 and Server 2008 NOSs.






14. The organization of files and directories (or folders) on a disk in which directories may contain files and other directories. When displayed graphically - this organization resembles a treelike structure.






15. A routine of sequential instructions that runs until it has achieved its goal.






16. A gateway that can translate IP fax data into analog fax data and vice versa.






17. A logical receptacle for holding objects with similar characteristics or privileges in an NOS directory. Containers form the branches of the directory tree.






18. An object in an operating system's directory - such as a printer or user - that does not contain other objects.






19. An access point that provides routing functions.






20. A means of collectively managing users' permissions and restrictions applied to shared resources.






21. A type of permission - or right - that is passed down from one group (the parent) to a group within that group (the child).






22. A type of wireless system in which the locations of the transmitter and receiver are static.






23. A multiprocessing method that assigns each subtask to a specific processor.






24. A type of wireless transmission in which signals travel over a single frequency or within a specified frequency range.






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. A popular remote file system created by Sun Microsystems - and available for UNIX and Linux operating systems.






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






28. The proprietary version of UNIX that comes from Bell Labs.






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






30. A computer that manages multiple media gateways and facilitates the exchange of call control information between these gateways.






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






32. A LAN that uses wireless connections for some or all of its transmissions.






33. The computer instructions written in a programming language that is readable by humans.






34. 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.






35. The term used to refer to a satellite that maintains a constant distance from a point on the equator at every point in its orbit.






36. A method of satellite Internet access in which a subscriber receives data via a satellite downlink transmission - but sends data to the satellite via an analog modem (dialup) connection.






37. A variable property associated with a network object. For example - a restriction on the time of day a user can log on is an attribute associated with that user object.






38. 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.






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






40. A type of wireless transmission in which lower-level signals are distributed over several frequencies simultaneously.






41. A service that transmits faxes over a TCP/IP network.






42. In the context of wireless networking - the process of a station establishing a connection (or associating) with a different access point.






43. A type of antenna that issues wireless signals along a single direction - or path.






44. On a network following the H.323 standard - any node that provides audio - visual - or data information to another node.
