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






26. A type of software license that - for a fixed price - allows any number of users in one location to legally access a program.






27. 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.






28. The ability of a processor to perform multiple activities in a brief period of time (often seeming simultaneous to the user






29. 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.






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






31. The relative strength over a three-dimensional area of all the electromagnetic energy an antenna sends or receives.






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






33. In the context of wireless signal propagation - the phenomenon that occurs when an electromagnetic wave encounters an obstruction and splits into secondary waves. The secondary waves continue to propagate in the direction in which they were split. Th
