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 access protocol. It runs over TCP/IP and is the standard file access protocol used by Windows operating systems.






2. 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.






3. A type of trust relationship in which two domains that belong to different NOS directory trees are configured to trust each other.






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






5. A protocol that enables one system to access files on another system.






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






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






8. 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.|






9. A logical representation of multiple - hierarchical levels in a directory.






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






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






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






13. A service that runs on a client workstation and determines whether the client's request should be handled by the client or the server.






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






15. 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.






16. 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.






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






18. A type of wireless transmission in which lower-level signals are distributed over several frequencies simultaneously.






19. A series of two or more commands in which the output of prior commands is sent to the input of subsequent commands.






20. The GUI environment for UNIX and Linux systems.






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






22. A variable property associated with a network object. For example - a restriction on the time of day a user can log on is an attribute associated with that user object.






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






24. 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.






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 the context of applications - a licensing mode that limits access to an application to specific users or workstations.






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






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






29. 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.






30. The process of copying Active Directory data to multiple domain controllers. This ensures redundancy so that in case one of the domain controllers fails - clients can still log on to the network - be authenticated - and access resources.






31. In Windows Server 2003 or Server 2008 networking - the single domain from which child domains branch out in a domain tree.






32. A wireless networking standard that uses FHSS (frequency hopping spread spectrum) signaling in the 2.4-GHz band to achieve a maximum throughput of either 723 Kbps or 2.1 Mbps - depending on the version. IT was designed for use primarily with small of






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






34. A private switch that accepts and interprets both analog and digital voice signals (although some IP-PBXs do not accept analog lines). It can connect with both traditional PSTN lines and data networks. |






35. A group of users - servers - and other resources that share account and security policies through a Windows Server 2003 or Server 2008 NOS.






36. 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.






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






38. In the context of 802.11n wireless technology - the combination of two 20-MHz frequency band to create one 40-MHz frequency band that can carry more than twice the amount of data that a single 20-MHz band could. It's recommended for use only in the 5






39. The brand of computer central processing unit invented by and used in Sun Microsystems servers.






40. 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.






41. The provision of telephone service over the Internet.






42. On a SIP network - a server that accepts requests for location information from user agents - then queries the nearest registrar server on behalf of those user agents. If the recipient user agent is in the SIP proxy server's domain - then that server






43. In wireless networking - the process that describes a station moving between BSSs without losing connectivity.






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






45. Another term for the UNIX command interpreter.






46. A record of a user that contains all of her properties - including rights to resources - password - user name - and so on.






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






48. The nerve center for networks that adhere to H.323. IT authorize and authenticate terminals and gateways - manage bandwidth - and oversee call routing - accounting - and billing.






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






50. In IEEE terminology - a group of stations that share an access point.
