  • 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 online documentation for any variety of the UNIX operating system. This documentation describes the use of the commands and the programming interface.






2. A standard protocol for accessing network directories.






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






4. 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.






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






6. 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.






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






8. In the DiffServ QoS technique - a forwarding specification that assigns each data stream a minimum departure rate from a given node. This technique circumvents delays that slow normal data from reaching its destination on time and in sequence.






9. In LDAP naming conventions - the name of an object.






10. In the context of wireless - the phenomenon that occurs when an electromagnetic wave encounters an obstacle and bounces back toward its source.






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






12. 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.






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






14. A protocol suite codified by the IETF (in RFC 2543) as a set of Session layer signaling and control protocols for multiservice - packet-based networks.






15. The technique of splitting tasks among multiple processors to expedite the completion of any single instruction.






16. 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






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






18. 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.






19. 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






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






21. Another term for the UNIX command interpreter.






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






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






24. A network access method used on 802.11 wireless networks. In it - before a node begins to send data it checks the medium. If it detects no transmission activity - it waits a brief - random amount of time - and then sends its transmission. If the node






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






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






27. The term used to refer to the different implementations of a particular UNIX or Linux system. For example - different distributions of Linux include Fedora - SUSE - and Ubuntu.






28. 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.






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






30. A nonprofit industry association that owns the UNIX trademark.






31. 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.






32. The geographical area in which signals issued from an antenna or wireless system can be consistently and accurately received.






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






34. A Windows Server 2003 or Server 2008 computer that contains a replica of the Active Directory database.






35. A service in which a video stored as an encoded file is delivered to a viewer upon his request.






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






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






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






39. A UNIX service responsible for printing files placed in the printer queue by the lpr command.






40. 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






41. 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






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






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






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






45. The brand of computer central processing unit invented by and used in Sun Microsystems servers.






46. A type of satellite Internet access service in which a subscriber sends and receives data to and from the Internet over the satellite link. This is a symmetrical technology - in which both upstream and downstream throughputs are advertised to reach 4






47. The ability of a processor to perform multiple activities in a brief period of time (often seeming simultaneous to the user






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






49. A freely distributable implementation of a UNIX-type of system. Finnish computer scientist Linus Torvalds originally developed it.






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