26. On a network following the H.323 standard - a gateway that provides translation between network devices running H.323 signaling protocols and devices running other types of signaling protocols (for example - SS7 on the PSTN).






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






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






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

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






32. 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.






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






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






35. A type of WLAN in which stations communicate with an access point and not directly with each other.






36. A type of wireless LAN in which stations communicate directly with each other (rather than using an access point).






37. An internal or externally attached adapter that converts analog telephone signals into packet-switched voice signals and vice-versa.






38. A type of antenna that issues and receives wireless signals with equal strength and clarity in all directions. This type of antenna is used when many different receivers must be able to pick up the signal - or when the receiver's location is highly m
