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.

2. An open source software package that provides complete Windows-style file- and printer-sharing capabilities.






3. A series of two or more commands in which the output of prior commands is sent to the input of subsequent commands.






4. A client or server operating system originally developed by researchers at AT&T Bell Laboratories in 1969.






5. 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.






6. An IEEE standard for wireless MANs. Its networks may use frequencies between 2 and 66 GHz. Their antennas may operate in a line-of-sight or non-line-of-sight manner and cover 50 kilometers (or approximately 30 miles). Its connections can achieve a ma






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






8. The name given to the public software project to implement a complete - free source code implementation of UNIX. It also refers to the collection of UNIX-inspired utilities and tools that are included with Linux distributions.|






9. A domain established within another domain in a Windows Server 2003 or Server 2008 domain tree.






10. A proprietary implementation of the UNIX operating system by Sun Microsystems.






11. Any implementation of UNIX for which the source code is either unavailable or available only by purchasing a licensed copy from Novell (costing as much as millions of dollars).






12. The geographical area in which signals issued from an antenna or wireless system can be consistently and accurately received.






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






14. A customizable - graphical network management interface introduced with Windows Server 2003 and incorporated in Window Server 2008's Server Manager.






15. Another term for the UNIX command interpreter.






16. A group of access points and associated stations (or basic service sets) connected to the same LAN.






17. The type of multitasking in which tasks are actually performed one at a time - in very brief succession. One program uses the processor for a certain period of time - then is suspended to allow another program to use the processor.






18. A computer that provides support for multiple H.323 terminals (for example - several workstations participating in a videoconference) and manages communication between them.






19. A well-defined - self-contained subset of a process. U






20. The term used to refer to a satellite that maintains a constant distance from a point on the equator at every point in its orbit.






21. The relationship between two domains on a Windows Server 2003 or Server 2008 network that allows a domain controller from one domain to authenticate users from the other domain.






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






23. The process of making a disk partition available.






24. A logical representation of a networked printer's functionality.






25. The description of object types - or classes - and their required and optional attributes that are stored in an NOS's directory.






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






27. A type of antenna that issues wireless signals along a single direction - or path.






28. A protocol suite codified by the IETF (in RFC 2543) as a set of Session layer signaling and control protocols for multiservice - packet-based networks.






29. 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.






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






31. An ITU standard that describes an architecture and a suite of protocols for establishing and managing multimedia services sessions on a packet-switched network.






32. A program (usually text-based) that accepts and executes system programs and applications on behalf of users. Often - it includes the ability to execute a series of instructions that are stored in a file.






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






34. The proprietary version of UNIX that comes from Bell Labs.






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






36. In the context of wireless networking - the process of a station establishing a connection (or associating) with a different access point.






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






38. 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.






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






40. The IEEE standard for a wireless networking technique that uses DSSS (directsequence spread spectrum) signaling in the 2.4-2.4835-GHz frequency range (also called the 2.4-GHz band). It separates the 2.4-GHz band into 14 overlapping 22-MHz channels an
