12. In 802.11 wireless networking - a type of frame issued by a station during active scanning to find nearby access points.






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






14. 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.






15. 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.






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






17. 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

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






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






34. 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.






35. A telephone used for VoIP on a TCP/IP-based network.






36. A service in which television signals from broadcast or cable networks travel over packet-switched networks.






37. A small (usually home) network composed of personal communications devices.






38. In SIP terminology - a server that responds to user agent clients' requests for session initiation and termination.






39. A wireless signaling technique in which a signal jumps between several different frequencies within a band in a synchronization pattern known to the channel's receiver and transmitter.

45. In Microsoft terminology - the type of client/server network that relies on domains - rather than workgroups.






46. 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






47. 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.






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






49. 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
