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. Physical Layer






2. Standard rating that indicates the diameter of a wire






3. A type of transmission in which the entire channel capacity of the communications medium (such as cable) is used by one data signal - enabling only one node to transmit at a time.






4. Rules determining the format and transmission of data






5. Indication a system has just been attacked or is under attack






6. Layer 7






7. An internetwork is two or more computer networks connected together.






8. Method of controlling how network nodes access communication channels - ex highway






9. Tool used to determine whether a customers line is obtaining dial tone from the CO






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






11. A worldwide network network of interconnected LANs - and MANs - that uses the TCP/IP protocol to enable people to share e-mail messages and computer files and to access a vast array of infromation.






12. Requires many pulses to transmit same info that an analog can transmit in a wave






13. An Application layer protocol used to retrieve messages from a mail server. When a client retrieves mail via POP - messages previously stored on the mail server are downloaded to the client's workstation - and then deleted from the mail server.






14. A utility for viewing or modifying a host's routing table






15. A computer that accesses another computer - such as a workstation that accesses a shared file on another workstation - server - or mainframe. The client may use the accessed computer (host) to process data - or may process accessed data using its own






16. Unique identifying number for a network node; follows a hierarchical addressing scheme; can be assigned through OS software; added to data packets and interpreted by protocols at the Network layer






17. The transmission capacity of a communications medium - which is typically measured in bits per second (for data transmissions) or hertz (for data - voice - and video transmissions) - and which is determined by the maximum minus the minimum transmissi






18. The process of determining the best path from Point A on one network to Point B on another






19. The shorter the wavelength






20. Measure of frequency equivalent to the number of amplitude cycles per second






21. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet creation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






22. Protocol data unit. An OSI term to refer generically to a grouping of information by a particular layer of the OSI model. More specifically - an LxPDU would imply the data and headers as defined by Layer x.






23. A single physical/non-physical medium for connecting computers






24. (fix) if analog an amplifier or if digital with repeater






25. Pieces of hardware that connect the wire to the network device






26. Process of retransmitting a digital signal; repeats the pure signal without the noise






27. Associates a MAC address with a given IP address - reverse ARP






28. Connectivity device - data link layer (2) - reads header info to forward packets according to MAC addresses






29. As defined by the EIA/TIA-568 standard - cable that runs between network equipment rooms - floors - and buildings.






30. Connects multiple LANs






31. Twist wire so you don't get interference on the memory






32. An arm of the Internet Society (ISOC) that works on Internet-relateed technical issues.






33. Different upload/download speeds.






34. Provides Internet access and/or other services such as email and Web hosting






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






36. Private connection from a LAN to an internet service provider.






37. Process of breaking large packets into smaller packets.






38. Representatives from electronics manufacturers across the US that sets standards for electronic equipment and lobbies for legislation favorable to the growth of the computer and electronics industries






39. Alert or alarm that occurs in the absence of an actual attack






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






41. MIB






42. Any device connected to a network - such as a microcomputer - mainframe - midrange computer - network equipment - or printer. Also called a station.






43. Is a protocol for defining host groups.






44. Speed: 100 Mbps - Alternative name: 10BASE-TX - IEEE Standard: IEEE 802.3u - Cable Type: Copper - max length 100m






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






46. Vulnerability created in a system by a virus or worm which allows the attacker to access the system at will with special privileges.






47. A wireless station listens on all channels for a bacon frame from an access point






48. Used to determine where patch cable for a specific server terminates on the patch panel - and checks for the presence of noise on a wire






49. This phase begins and end a PPP session.






50. Secures messages being transmitted on the internet - uses RSA for authentication and encyption.
