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. The term used to describe software that is distributed with few restrictions and whose source code is freely available.






2. An end node on a network; used most often in the context of wireless networks. transponder






3. The IEEE standard for a wireless networking technique that uses multiple frequency bands in the 5-GHz frequency range and provides a theoretical maximum throughput of 54 Mbps.






4. A series of two or more commands in which the output of prior commands is sent to the input of subsequent commands.






5. A method of multiprocessing that splits all operations equally among two or more processors.






6. A customizable - graphical network management interface introduced with Windows Server 2003 and incorporated in Window Server 2008's Server Manager.






7. A representation of a thing or person associated with the network that belongs in the NOS directory.






8. A connection from an orbiting satellite to an Earth-based receiver.






9. 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.






10. A type of antenna that issues and receives wireless signals with equal strength and clarity in all directions. This type of antenna is used when many different receivers must be able to pick up the signal - or when the receiver's location is highly m






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






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






13. A protocol that enables one system to access files on another system.






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






15. A wireless signaling technique in which a signal jumps between several different frequencies within a band in a synchronization pattern known to the channel's receiver and transmitter.






16. The RAM chips installed on the computer's system board that provide dedicated memory to that computer.






17. The process of moving blocks of information - called pages - between RAM and into a page file on disk.






18. In the context of applications - a licensing mode that limits access to an application to specific users or workstations.






19. A small (usually home) network composed of personal communications devices.






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






21. A record of a user that contains all of her properties - including rights to resources - password - user name - and so on.






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






23. A well-defined - self-contained subset of a process. U






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






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






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






27. The name of the primary file system used in most Linux distributions.






28. A service that runs on a client workstation and determines whether the client's request should be handled by the client or the server.






29. A wireless signal or path that travels directly in a straight line from its transmitter to its intended receiver.






30. The provision of telephone service over the Internet.






31. The term used to describe the recently released standards for highthroughput - long-distance digital data exchange over wireless connections.






32. An attribute of an object that identifies the object separately from its related container(s) and domain.






33. A type of WLAN in which stations communicate with an access point and not directly with each other.






34. The IEEE standard for a wireless networking technique that may issue signals in the 2.4- or 5-GHz band and can achieve actual data throughput between 65 and 600 Mbps. It accomplishes this through several means - including MIMO - channel bonding - and






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






36. In the context of Windows Server 2003 or Server 2008 - a collection of domain trees that use different namespaces. It allows for trust relationships to be established between trees.






37. The security relationship between domains in the same domain tree in which one domain grants every other domain in the tree access to its resources and - in turn - that domain can access other domains' resources.






38. A UNIX command that places files in the printer queue.






39. A wireless networking standard that uses FHSS (frequency hopping spread spectrum) signaling in the 2.4-GHz band to achieve a maximum throughput of either 723 Kbps or 2.1 Mbps - depending on the version. IT was designed for use primarily with small of






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






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






42. A type of wireless system in which the receiver can be located anywhere within the transmitter's range. This allows the receiver to roam from one place to another while continuing to pick up its signal.






43. The IEEE standard for a wireless networking technique that uses DSSS (directsequence spread spectrum) signaling in the 2.4-2.4835-GHz frequency range (also called the 2.4-GHz band). It separates the 2.4-GHz band into 14 overlapping 22-MHz channels an






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






45. In the context of IPTV - a device that decodes digital video signals and issues them to the television.






46. A telephone switch used to connect calls within a private organization.






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






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






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






50. The process of copying Active Directory data to multiple domain controllers. This ensures redundancy so that in case one of the domain controllers fails - clients can still log on to the network - be authenticated - and access resources.
