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






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






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






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






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






7. The organization of files and directories (or folders) on a disk in which directories may contain files and other directories. When displayed graphically - this organization resembles a treelike structure.






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






9. A change in a wireless signal's strength as a result of some of the electromagnetic energy being scattered - reflected - or diffracted after being issued by the transmitter.






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






11. 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






12. The exchange of information between the components of a network or system for the purposes of establishing - monitoring - or releasing connections as well as controlling system operations.






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






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






15. 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.






16. A portion of the kernel that you can load and unload to add or remove functionality on a running UNIX or Linux system.






17. The provision of telephone service over a packet-switched network running the TCP/IP protocol suite.






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






19. In Microsoft terminology - a group of interconnected computers that share each others' resources without relying on a central file server.






20. In the context of wireless signal propagation - the phenomenon that occurs when an electromagnetic wave encounters an obstruction and splits into secondary waves. The secondary waves continue to propagate in the direction in which they were split. Th






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






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






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






24. 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.






25. 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.






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






27. A standard protocol for accessing network directories.






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






29. The brand of computer central processing unit invented by Apple Computer - IBM - and Motorola - Inc. - and used in IBM servers.






30. A pictorial representation of computer functions and elements that - in the case of NOSs - enables administrators to more easily manage files - users - groups - security - printers - and other issues.






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






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






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






34. 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.






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






36. 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.






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






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






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






40. A method of satellite Internet access in which a subscriber receives data via a satellite downlink transmission - but sends data to the satellite via an analog modem (dialup) connection.






41. A type of object recognized by an NOS directory and defined in an NOS schema.






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






43. In Microsoft terminology - the type of client/server network that relies on domains - rather than workgroups.






44. 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.






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






46. 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).






47. In the context of wireless networking - a frame issued by an access point to alert other nodes of its existence.






48. 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.






49. In the context of wireless networking - the communication that occurs between a station and an access point to enable the station to connect to the network via that access point.






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