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

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






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






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






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






7. 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






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






9. 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.






10. 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.

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






22. 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.






23. 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.






24. 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.






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






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






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






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






29. An access point that provides routing functions and is used as a gateway.






30. 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.






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






32. The centralized management of multiple types of network-based communications - such as voice - video - fax - and messaging services.






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






34. 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.






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






36. The type of multitasking in which tasks are actually performed one at a time - in very brief succession. One program uses the processor for a certain period of time - then is suspended to allow another program to use the processor.






37. A representation of a thing or person associated with the network that belongs in the NOS directory.






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






39. On a network following the H.323 standard - a gateway that provides translation between network devices running H.323 signaling protocols and devices running other types of signaling protocols (for example - SS7 on the PSTN).
