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. Translates data to a format the receiving node understands - such as from EBCDIC to ASCII - Performs data encryption - Performs data compression






2. The first set of six characters that make up the MAC address and that are unique to a particular manufacturer.






3. A medium that carries 1 signal






4. The process of wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer. For example - Data Link layer protocols encapsulate Network layer packets in frames.






5. Network segment that contains end nodes - such as workstations






6. Used with single mode or multi mode fiber optic cable






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






8. Restructuring data units that have been segmented






9. Open Systems Interconnection model is standard description or reference model for how messages should be transmitted between any 2 points in a telecommunications network.






10. Radio frequency interference






11. A generic term referring to any set of protocols and standards collected into a comprehensive grouping that - when followed by the devices in a network - allows all the devices to communicate. Examples include TCP/IP and OSI.






12. Modulation technique in which the amplitude of the carrier signal is modified by the application of a data signal






13. Public switched telephone network






14. A Data Link sublayer that examines addressing information contained in a network frame and controls how devices share communications on the same network.






15. Unit of data that results from subdividing a larger protocol data unit






16. Radio frequency interference. interference caused by radio.






17. Which protocol provides the user with many functions of the world wide web?






18. Strategy in which all IDPS control functions are implemented and managed in a central location






19. Frequency modulation-frequency of signal is modified






20. Process of grouping almost identical alarms occurring at almost same time into single higher-level alarm






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






22. Which layer in the OSI is responsible for routing and controling the flow of packets around the network?






23. MMF






24. IPX






25. Computers connected together within a limited geographical area






26. Network Layer






27. What does POP3 stand for?






28. Firewall packet inspection that ignores the state of the connection between the internal computer and the external computer - only blocks or allows a packet based on header information.






29. Ethernet NICs listen on network and wait until they detect no other nodes transmitting data






30. Faster wireless standard 20-25






31. The utility that allows you to query ICANN's DNS registration database and find information about a domain.






32. Digital - one signal one channel at a time (half duplexing) ex. ethernet






33. Hardware address of the network interface card






34. Frequency Division Multiple Access






35. Two twisted wire pairs. It's the oldes type and is only voice grade - it isn't rated for data communication.






36. Defines the physical characteristics of the network






37. An 8-bit character-coding method consisting of 96 uppercase and lowercase characters and numbers - plus 32 nonprinting characters.






38. Central component of a cable designed to carry a signal






39. Protocol data unit






40. Signal interference caused by magnetic force field generated by electrical devices such as motors.






41. Tools in order to connect a new RJ45






42. Provides FTP - HTTP - SMTP...






43. A specialized UN agency that provides developing countries with technical expertise and equipment






44. Also called the physical or MAC address - the hexadecimal number permanently assigned to a network interface and used by the MAC sublayer within the DATA Link layer (Layer 2).






45. MX






46. Developed by ISO and ANSI - a model that providees a framework for networked hardware and software communication based on seven layers.






47. Signals travel in both directions but only one at a time






48. A technique for connecting to a network at a remote location using Internet as the medium.






49. Layer 4






50. Layer 3 Troubleshooting
