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.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. In IEEE terminology - a group of stations that share an access point.






2. The term used to refer to the different implementations of a particular UNIX or Linux system. For example - different distributions of Linux include Fedora - SUSE - and Ubuntu.






3. A proprietary implementation of the UNIX system distributed by IBM.






4. A character that enables you to combine existing commands to form new commands.






5. The capability for operating multiple logical servers






6. A transmission technique in which a signal's bits are distributed over an entire frequency band at once. Each bit is coded so that the receiver can reassemble the original signal upon receiving the bits.






7. Another term for the UNIX command interpreter.






8. The provision of telephone service over a packet-switched network running the TCP/IP protocol suite.






9. A version of Linux packaged and distributed by Red Hat.






10. An object in an operating system's directory - such as a printer or user - that does not contain other objects.






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






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






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






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






15. In Windows Server 2003 or Server 2008 networking - the single domain from which child domains branch out in a domain tree.






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






17. 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.






18. 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.






19. A long form of an object's name in Active Directory that explicitly indicates the object name - plus the names of its containers and domains. It includes a DC (domain component) - OU (organizational unit) - and CN (common name).






20. The IEEE standard for a wireless networking technique that uses multiple frequency bands in the 5-GHz frequency range and provides a theoretical maximum throughput of 54 Mbps.






21. The provision of telephone service over the Internet.






22. A change in a wireless signal's strength as a result of some of the electromagnetic energy being scattered - reflected - or diffracted after being issued by the transmitter.






23. The technique of splitting tasks among multiple processors to expedite the completion of any single instruction.






24. A Session layer control protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for controlling a session between two nodes. For example - it ensures that the two nodes are communicating in the same format.






25. A command-line utility for viewing and setting wireless interface parameters on Linux and UNIX workstations.






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






27. A portion of the kernel that you can load and unload to add or remove functionality on a running UNIX or Linux system.






28. A UNIX distribution that originated at the University of California at Berkeley.






29. A type of satellite that orbits the Earth with an altitude between 100 and 900 miles - closer to the Earth's poles than the orbits of either GEO or MEO satellites.






30. The IEEE standard for a wireless networking technique designed to be compatible with 802.11b while using different encoding techniques that allow it to reach a theoretical maximum capacity of 54 Mbps. It uses the 2.4-GHz frequency band.






31. A logical representation of multiple - hierarchical levels in a directory.






32. The memory that is logically carved out of space on the hard drive and added to physical memory (RAM).






33. A GUI tool provided with Windows Server 2008 that enables network administrators to manage server roles - features - resources - and users from a single interface.






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






35. An exchange in which a wireless station requests the exclusive right to communicate with an access point and the access point confirms that it has granted that request.






36. The term used to describe the recently released standards for highthroughput - long-distance digital data exchange over wireless connections.






37. In the context of wireless networking - the communication that occurs between a station and an access point to enable the station to connect to the network via that access point.






38. A service that uses the ATM network access method (and ATM cells) to transmit voice signals over a network.






39. A record of a user that contains all of her properties - including rights to resources - password - user name - and so on.






40. A continuum of electromagnetic waves used for data and voice






41. A type of satellite that orbits the Earth roughly 6000 to 12 -000 miles above its surface - positioned between the equator and the poles. These satellites can cover a larger area of the Earth's surface than LEO satellites while using less power and c






42. The IEEE standard for a wireless networking technique that may issue signals in the 2.4- or 5-GHz band and can achieve actual data throughput between 65 and 600 Mbps. It accomplishes this through several means - including MIMO - channel bonding - and






43. A user account that has unlimited privileges to resources and objects managed by a server or domain.






44. A network access method used on 802.11 wireless networks. In it - before a node begins to send data it checks the medium. If it detects no transmission activity - it waits a brief - random amount of time - and then sends its transmission. If the node






45. 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.






46. An area of a computer's hard drive that is logically defined and acts as a separate disk drive.






47. The online documentation for any variety of the UNIX operating system. This documentation describes the use of the commands and the programming interface.






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






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






50. An attribute of an object that identifies the object separately from its related container(s) and domain.
