Comptia Network + Wireless NOS Voip

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. A program (usually text-based) that accepts and executes system programs and applications on behalf of users. Often - it includes the ability to execute a series of instructions that are stored in a file.






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






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






4. The capability for operating multiple logical servers






5. An exchange in which a wireless station requests the exclusive right to communicate with an access point and the access point confirms that it has granted that request.






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






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






8. Any implementation of UNIX for which the source code is either unavailable or available only by purchasing a licensed copy from Novell (costing as much as millions of dollars).






9. 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






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






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

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






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






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






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






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






19. In the context of 802.11n wireless networking - the ability for access points to issue multiple signals to stations - thereby multiplying the signal's strength and increasing their range and data-carrying capacity.






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






21. A type of wireless LAN in which stations communicate directly with each other (rather than using an access point).






22. An IEEE standard for wireless MANs. Its networks may use frequencies between 2 and 66 GHz. Their antennas may operate in a line-of-sight or non-line-of-sight manner and cover 50 kilometers (or approximately 30 miles). Its connections can achieve a ma






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






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






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






26. The provision of telephone service over the Internet.






27. A file on the hard drive that is used for virtual memory.






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






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






30. A device used on wireless LANs that transmits and receives wireless signals to and from multiple nodes and retransmits them to the rest of the network segment. Those can connect a group of nodes with a network or two networks with each other. They ma






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






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






33. 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.






34. The process of making a disk partition available.






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






36. 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.






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






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






39. 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.






40. In the context of wireless networking - the process in which a station listens to several channels within a frequency range for a beacon issued by an access point.






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






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