Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

24. In Microsoft terminology - a group of interconnected computers that share each others' resources without relying on a central file server.






25. The organization of files and directories (or folders) on a disk in which directories may contain files and other directories. When displayed graphically - this organization resembles a treelike structure.






26. A logical receptacle for holding objects with similar characteristics or privileges in an NOS directory. Containers form the branches of the directory tree.






27. An area covered by a wireless access point that provides visitors with wireless services - including Internet access.






28. 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






29. A type of satellite Internet access service in which a subscriber sends and receives data to and from the Internet over the satellite link. This is a symmetrical technology - in which both upstream and downstream throughputs are advertised to reach 4






30. A service that runs on a client workstation and determines whether the client's request should be handled by the client or the server.






31. In LDAP naming conventions - the name of any one of the domains to which an object belongs.
