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. The information transfered between layers in the same OSI stack






2. Wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer






3. A device that must be located at each end of a leased line.






4. Works closely with IP in providing error and control information - by allowing hosts to exchange packet status information to help move the packets along the internetwork






5. Area above the ceiling tile or below the subfloor in a building






6. A computer (mainframe - minicomputer - server - or workstation) that has an operating system enabling multiple computers to access it at the same time for files - data - and services.






7. A network that links multiple LAN's in large city or metropolitan region.






8. To make more efficient use of limited numbers of legitimate IP addressing






9. 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






10. An adapter board designed to connect a workstation - server - or other network device to a network medium.






11. Delay between the transmission of a signal and its receipt






12. A cable TV company - such as Comcast Broadband.






13. Equals a single pulse in the digital encoding system






14. F type (like TV cable) or BNC (crimped)






15. Four twisted wire pairs with three twists per foot. This type can handle transmissions up to 16 MHz. Now limited to telecommunication equipment






16. MSAU






17. Http - Hypertext transfer protocol






18. Fiber Distributed Data Interface






19. Layer 5






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






21. A computer on a network that requests services or resources from another computer on a network






22. POE standard






23. Application Layer






24. A service provided with Windows 98 - Me - 2000 - and 32-bit versions of XP operating systems that allows one computer - the ICS host - to share its Internet connection with other computers on the same network.






25. SLIP






26. LDAP






27. Application Layer






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






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






30. A protocol data unit that has been transfered between OSI layers and then stripped of control information and transfere instructions.






31. In TCP - a term used to describe a TCP header and its encapsulated data (also called an L4PDU). Also in TCP - the process of accepting a large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In






32. Communications for continuous burst of data controlled by a clock signal that starts each burst.






33. Regular voice-grade telephone service.






34. Each node is connected to the two nearest nodes so that the entire network forms a circle - active - twisted pair of fiber optic - single malfunction in workstation can disable entire network - not flexible or scalbe






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






36. Is a secure form of HTTP






37. A station checks for existing wireless transmissions before starting the transmission






38. Method of data modulation in which the frequency of the carrier signal is modified by the application of the data signal






39. A TCP/IP troubleshooting utility that uses ICMP to trace the path from one networked node to another - identifying all intermediate hops between the two nodes. Traceroute is useful for determining router or subnet connectivity problems. On Windows-ba






40. Uses frame headers






41. Process in which an NIDPS inspects the higher-order protocols (HTTP - FTP - Telnet) are examined for unexpected packet behavior or improper use






42. Running system for a while to track types of false positives it generates and then adjusting IDPS alarm classifications






43. A series of interconnected computers - printing devices - and other computer equipment that shares hardware and software resources. The service area usually is limited to a given office area - floor - or building.






44. A variation of CHAP designed by Microsoft






45. 500 meters - 10Mbps






46. Physical Layer






47. All wires are reversed






48. ISDN






49. Unwanted signals from sources near network cabling - such as motors and power lines






50. A resistor that is connected to the end of a segment on a bus network - so that data-carrying signals are absorbed at the point where the segment stops. Absorbing the signals ensures they are not reflected back onto the cable after they reach the end
