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.

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






3. In Microsoft terminology - the primary purpose of a Windows Server 2008 server.






4. A Session layer call signaling protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for call or videoconference setup between nodes on a VoIP or video-over-IP network - indicating node status - requesting addit






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






6. A service that relies on a DSL connection to transmit packetized voice signals.






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






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






9. A LAN that uses wireless connections for some or all of its transmissions.






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






11. A method used by wireless stations to detect the presence of an access point. The station issues a probe to each channel in its frequency range and waits for the access point to respond.






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






13. 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






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






15. 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.






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






17. 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.






18. A gateway that can translate IP fax data into analog fax data and vice versa.






19. 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.






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






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






22. A standard protocol for accessing network directories.






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






24. 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.






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






26. A protocol suite codified by the IETF (in RFC 2543) as a set of Session layer signaling and control protocols for multiservice - packet-based networks.






27. A service in which a video stored as an encoded file is delivered to a viewer upon his request.






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






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






30. 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.






31. A Transport layer protocol used with voice and video transmission. It operates on top of UDP and provides information about packet sequence to help receiving nodes detect delay and packet loss. It also assigns packets a timestamp that corresponds to






32. 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






33. A UNIX service responsible for printing files placed in the printer queue by the lpr command.






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. A part of the organizational structure of an operating system's directory that contains objects or other organizational units.






36. 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.






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






38. A telephone switch used to connect calls within a private organization.






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






40. A service that transmits faxes over a TCP/IP network.






41. A proprietary NOS from Apple Computer that is based on a version of UNIX.






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






43. 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.






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






45. The diffusion of a wireless signal that results from hitting an object that has smaller dimensions compared to the signal's wavelength.






46. On a network following the H.323 standard - any node that provides audio - visual - or data information to another node.






47. The process of making a disk partition available.






48. A type of wireless transmission in which signals travel over a single frequency or within a specified frequency range.






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






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