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






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






9. Any implementation of UNIX for which the source code is either unavailable or available only by purchasing a licensed copy from Novell (costing as much as millions of dollars).






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






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






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






13. 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.






14. 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.






15. A version of Linux packaged and distributed by Red Hat.






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






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






18. The IEEE standard for a wireless networking technique that uses DSSS (directsequence spread spectrum) signaling in the 2.4-2.4835-GHz frequency range (also called the 2.4-GHz band). It separates the 2.4-GHz band into 14 overlapping 22-MHz channels an






19. The brand of computer central processing unit invented by Apple Computer - IBM - and Motorola - Inc. - and used in IBM servers.






20. 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.






21. An object in an operating system's directory - such as a printer or user - that does not contain other objects.






22. 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






23. 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.






24. 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






25. 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.






26. 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.






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






28. A character that enables you to combine existing commands to form new commands.






29. 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.

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






37. 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
