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






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






3. 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.






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






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






6. In LDAP naming conventions - the name of any one of the domains to which an object belongs.






7. 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.






8. In the context of wireless networking - an assessment of client requirements - facility characteristics - and coverage areas to determine an access point arrangement that will ensure reliable wireless connectivity within a given area.






9. In the context of wireless - the phenomenon that occurs when an electromagnetic wave encounters an obstacle and bounces back toward its source.






10. The provision of telephone service over the Internet.






11. The IEEE standard for a wireless networking technique designed to be compatible with 802.11b while using different encoding techniques that allow it to reach a theoretical maximum capacity of 54 Mbps. It uses the 2.4-GHz frequency band.






12. The process of making a disk partition available.






13. 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.






14. A type of wireless system in which the receiver can be located anywhere within the transmitter's range. This allows the receiver to roam from one place to another while continuing to pick up its signal.






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






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






17. 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.






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






19. The GUI environment for UNIX and Linux systems.






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






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






22. 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.






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






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






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






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






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






28. A highly privileged user ID that has all rights to create - delete - modify - move - read - write - or execute files on a UNIX or Linux system.






29. The real-time reception and transmission of images and audio among two or more locations.






30. 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.|






31. A service that uses the ATM network access method (and ATM cells) to transmit voice signals over a network.






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






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






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






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






36. 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






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






38. A long form of an object's name in Active Directory that explicitly indicates the object name - plus the names of its containers and domains. It includes a DC (domain component) - OU (organizational unit) - and CN (common name).






39. An area covered by a wireless access point that provides visitors with wireless services - including Internet access.






40. Currently - the most popular version of WiMAX. IEEE improved the mobility and QoS characteristics of the technology - making it better suited to VoIP and mobile phone users.






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






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






43. Another term for the UNIX command interpreter.






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






45. 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.






46. 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

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






49. A network access method used on 802.11 wireless networks. In it - before a node begins to send data it checks the medium. If it detects no transmission activity - it waits a brief - random amount of time - and then sends its transmission. If the node
