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.

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






3. Another term for the UNIX command interpreter.






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






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






6. An open source software package that provides complete Windows-style file- and printer-sharing capabilities.






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






8. A UNIX distribution that originated at the University of California at Berkeley.






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






10. The relative strength over a three-dimensional area of all the electromagnetic energy an antenna sends or receives.






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






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






13. A part of the organizational structure of an operating system's directory that contains objects or other organizational units.






14. 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.






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






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






17. A continuum of electromagnetic waves used for data and voice






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






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






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






21. In SIP terminology - end-user devices such as workstations - PDAs - cell phones - or IP telephones. It initiates a SIP connection.






22. A proprietary implementation of the UNIX operating system by Sun Microsystems.






23. As specified in RFC 2205 - a QoS technique that attempts to reserve a specific amount of network resources for a transmission before the transmission occurs.






24. A 128-bit number generated and assigned to an object upon its creation in Active Directory.






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






26. 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.






27. 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.






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






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






30. 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.






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






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






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






34. A companion protocol to RTP - defined in RFC 3550 by the IETF - RTCP provides feedback on the quality of a call or videoconference to its participants.






35. 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.






36. The relationship between two domains on a Windows Server 2003 or Server 2008 network that allows a domain controller from one domain to authenticate users from the other domain.






37. 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.






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






39. A proprietary NOS from Apple Computer that is based on a version of UNIX.






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






41. 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.






42. In the context of 802.11n wireless technology - the combination of two 20-MHz frequency band to create one 40-MHz frequency band that can carry more than twice the amount of data that a single 20-MHz band could. It's recommended for use only in the 5






43. The memory that is logically carved out of space on the hard drive and added to physical memory (RAM).






44. A technique for ensuring QoS by prioritizing traffic.






45. 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.






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






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