Subject : it-skills
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. Virture privat network






2. Term that describes current anti-intrusion technologies






3. Unit of data at any layer of the OSI model






4. ATM






5. The process of validating a user.






6. Which protocol allows the transfer of a file from one computer to another over the network?






7. A type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.






8. Twisted pair cable consisting of a number of twisted pairs of copper wire with a simple plastic casing. Because - no shielding is used in this cable - it is very susceptible to EMI - RFI - and other types of interference






9. Asynchronous digital subscriber line. Method of providing internet service that uses the standard phone line - but transmits data at a different frequency than voice. Faster than ISDN.






10. OU






11. Long reach. multimode max length is 550 meters. single mode max length is 5000. 1000 mpbs. baseband transmission






12. BSD






13. The process of reconstructing segmented data






14. Networking technology developed by IBM in the 80s; relies upon direct links between nodes and ring topology - using tokens to allow nodes to transmit data






15. EFS






16. An established guideline that specifies how networked data is formatted into a packet or frame - how it is transmitted - and how it is interpreted at the receiving end.






17. Communications arrangement in which a single transmitter issues signals to multiple - defined recipients






18. IPv6 addressing - multicast group






19. A command-line utility that combines the functionality of the tracert and ping commands (similar to UNIX's mtr command) and comes with Windows XP - Vista - and Windows Server 2003 and Server 2008






20. A type of multimode fiber-optic cable that reflects the light-based signals like a mirror within the cable - resulting in different signals arriving at different times and with an increased likeihood of distortion over longer cable runs.






21. The general topic of how on one computer - two adjacent layers in a networking architectural model work together - with the lower layer proving services to the higher layer.






22. A Data Link sublayer of the OSI model that initiates the communication link between nodes and ensures the link is not unintentionally broken.






23. Standards organizations representing 157 countries headquartered in Geneva. Goal is to establish international standards to facilitate global exchange of information and barrier-free trade






24. FDDI






25. An authentication protocol that uses public key technology to provide users with secured access to network resources.






26. Tools in order to connect a new RJ45






27. After typing ping 127.0.0.1 - it tells you the test failed






28. HTTPS - Secure implementation of HTTP






29. Fiber optic - enables one fiber optic connection to carry multiple light signals simultaneously






30. LPD






31. Device that enables networks or segments using different media to interconnect and exchange signals






32. Cross talk that occurs between wire pairs near the source of a signal






33. A app. loaded on a server included with Windows OS that enables remote access






34. Frequency modulation-frequency of signal is modified






35. A network topology in which all of the nodes are connected to a central line or bus






36. Which protocol is responsible for splitting data into packets and adding a header to each one?






37. Used to resolve NetBIOS names w IP address






38. Is usde to communicate time synchronization information between systemson a network






39. Connects networks larger than a LAN - but smaller than a WAN






40. Software that enables a computer to communicate with devices such as NICs - printers - monitors - and hard disk drives.






41. Method of gauging the appropriate rate of data transmission based on how fast he recipient can accept data






42. Loop back address for IPv6






43. Is a host-to-host protocol like TCP - however it does not include mechanisms for ensuring timely delivery






44. Electromagnetic interference. waves from electrical devices. ex. RFI






45. Frequency hoping spread spectrum: a signal jumps between several different frequencies






46. Pipeline used to contain and protect cabling; usually made from metal






47. A type of cable used in network wiring and is usually shielded - which means that it is more immune to interference then unshielded cables






48. Signals travel in one direction






49. Type of interference that may be caused by motors - power lines - televisions - copiers - etc






50. Ppp tunneling protocol
