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. 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






2. A digital communication service that uses the same network infrastructure as PSTN - but is expensive






3. UN agency that regulates international telecommunications and provides developing countries with technical expertise and equipment to advance their technological bases






4. Wavelength division multiplexing






5. Amplitude - frequency (Hz) - wavelength - wavy line






6. The way nodes responds to a collision






7. A unit of data transmitted on a network that contains control and address information corresponding to the OSI Data Link layer - or Layer 2.






8. Transport Layer






9. Controls how applications access network






10. Total amount of communication cable that make up a network.






11. AH






12. A mail retrieval protocol that improves on the shortcomings of POP. The single biggest advantage IMAP4 has relative to POP is that it allows users to store messages on the mail server - rather than always having to download them to a local machine.






13. Metropolitan area network






14. Encrypts






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






16. Layer 1 Troubleshooting






17. (fix) if analog shield twisted pairs or if digital with a repeater






18. Which protocol allows users to send emails?






19. Example of an internetwork






20. Hub/repeaters






21. Layer 1 Troubleshooting






22. This layer in the OSI network model breaks up the files into packets to allow them to be sent around the network.






23. Connector used with single mode and multimode fiber optic cable






24. Two communication systems establish 2-way communication prior to the exchange of data






25. IDPS that reviews log files from servers - network devices - and other IDPSs for signatures indicating an attack or intrusion






26. AMI






27. Zeroconf






28. Layer 2 Troubleshooting






29. Why are web pages viewed using HTTP?






30. Is used to route electronic mail through the internetwork






31. A term referring to a data-link header and trailer - plus the data encapsulated between the header and trailer.






32. Technique for formatting signals in which one property of a carrier wave is modified by the addition of a data signal during transmission






33. Reverse address resolution protocol






34. Does not operate at the application layer






35. NNTP






36. Analog - only one direction. radio frequency analog waves w differences in frequency. expensive - longer distance. ex. cable TV






37. User datagram protocol






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






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






40. Faster networking and inexpensive - flexible - easy to install






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






42. A systematic survey of all of the target organization's Internet addresses that is conducted to identify network services offered by hosts in that range






43. Multiple signals travel simultaneously - medium is separated into multiple channels






44. OSPF






45. Consists of single cable that connects all nodes on a network without intervening connectivity devices - inexpensive - hard to find source of error - not very fault tolerant - data is transmitted in one direction in the ring.






46. Also called the star-wired ring topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






47. What is a unique name that identifies an internet site called?






48. A data link protocol used for remote networking that is rarely used today.






49. Layer 4 Troubleshooting






50. Generates signals as changes in voltage at the NIC
