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






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






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






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






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






6. 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.






7. 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






8. 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.






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






10. A proprietary implementation of the UNIX operating system by Sun Microsystems.






11. The RAM chips installed on the computer's system board that provide dedicated memory to that computer.






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






13. A type of satellite that orbits the Earth roughly 6000 to 12 -000 miles above its surface - positioned between the equator and the poles. These satellites can cover a larger area of the Earth's surface than LEO satellites while using less power and c






14. 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.






15. A method of multiprocessing that splits all operations equally among two or more processors.






16. 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.






17. A protocol used for communication between media gateway controllers and media gateways.






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






19. 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.






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






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






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






23. A special identifier shared by BSSs that belong to the same ESS.






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






25. 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.






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






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






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






29. A client or server operating system originally developed by researchers at AT&T Bell Laboratories in 1969.






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






31. A customizable - graphical network management interface introduced with Windows Server 2003 and incorporated in Window Server 2008's Server Manager.






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






33. A unique character string used to identify an access point on an 802.11 network.






34. 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.






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






36. A type of permission - or right - that is passed down from one group (the parent) to a group within that group (the child).






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






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






39. 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.






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