22. The process a wireless station undergoes to find an access point.






23. A type of trust relationship in which two domains that belong to different NOS directory trees are configured to trust each other.






24. 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
