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 IEEE standard for a wireless networking technique designed to be compatible with 802.11b while using different encoding techniques that allow it to reach a theoretical maximum capacity of 54 Mbps. It uses the 2.4-GHz frequency band.






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






3. 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.






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






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






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






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






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






9. Another term for the UNIX command interpreter.






10. 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.






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






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






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






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






15. 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






16. The process a wireless station undergoes to find an access point.






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






18. 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






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






20. A collection of H.323 terminals - gateways - and MCUs that are managed by a single H.323 gatekeeper.






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






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






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






24. The name given to the public software project to implement a complete - free source code implementation of UNIX. It also refers to the collection of UNIX-inspired utilities and tools that are included with Linux distributions.|






25. A transmission technique in which a signal's bits are distributed over an entire frequency band at once. Each bit is coded so that the receiver can reassemble the original signal upon receiving the bits.






26. The signals made of electromagnetic energy that travel through the atmosphere.






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






28. Any type of video service - including IPTV - videoconferencing - and streaming video - that delivers video signals over packet-switched networks using the TCP/IP protocol suite.






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






30. A version of Linux packaged and distributed by Red Hat.






31. 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.






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






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






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






35. 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.






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






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






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






39. 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.






40. 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.






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






42. A protocol for communications and resource access between systems - such as clients and servers.






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






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






45. A streaming video - either on demand or live - that is delivered via the Web.






46. In SIP terminology - a server that responds to user agent clients' requests for session initiation and termination.






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






48. A logical representation of a networked printer's functionality.






49. 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.






50. A form of filename substitution - similar to the use of wildcards in Windows and DOS.
