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. A connector used to terminate coaxial cable used for transmitting television and broadband cable signals






2. Synchronises data exchange






3. A network design in which every node is connected to every other node - achieving fault tolerance.






4. Why are web pages viewed using HTTP?






5. Form of transmission in which digital signals are sent through direct current pulses applied to a wire; can only send one signal at a time






6. Virture privat network






7. Measure of the difference between the highest and lowest frequencies that a medium can transmit






8. Maximum arc into which you can loop a cable before you will cause data transmission errors






9. Name Of Layer 1






10. SSID






11. Standard rating that indicates the diameter of a wire






12. Extent to which a signal has weakened after traveling a given distance






13. A versatile - chainable serial-bus technology that connects up to 127 devices at speeds of 1.5 Mbps and 12 Mbps as well as 480 Mbps.






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






15. System founded on using 1s and 0s to encode information






16. Several ethernet nodes can be connected and can monitor traffic or access media simultaneously






17. Signal that uses variable voltage to create continuous waves - resulting in an inexact transmission






18. Uses frame headers






19. Transport Layer






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






21. The organized research of the Internet addresses owned or controlled by a target organization.






22. User datagram protocol






23. Coordinates and maintains communications between two nodes on the network






24. Protocol data unit






25. Telnet






26. The IEEE standard for broadband wireless metropolitan area networking (also known as WiMax)






27. Physical layer standard for serial communications






28. 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.






29. This phase begins and end a PPP session.






30. When pulses that represent bits follow one another along a single transmission






31. A logical process of combining bits. In ANDing - a bit with a value of 1 plus another bit with a value of 1 results in a 1. A bit with a value of 0 plus any other bit results in a 0.






32. Secure sockets layer-encyrpts TCP/IP transmission including web forms- en route b/w the client server using public key encryption technology






33. International Organization for Standardization






34. Physical Layer






35. Term that describes current anti-intrusion technologies






36. Short reach. only multimode-max length is 500. baseband transmission. 1000 mpbs.






37. Simple Network Management Protocol






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






39. The combination of an IP address's network ID and subnet information. By interpreting the address's extended network prefix - a device can determine the subnet to which an address belongs.






40. Ppp over ethernet






41. Also called the star-wired bus topology - a network design that combines the logial comunications of a bus with the physical layout of a star.






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






43. T1






44. Default subnet mask for 154.13.44.87






45. Using part of a leased line






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






47. Provides strung security for HTTP- transpored information - but it is only used by some vendor's application






48. Multiplexing technique use over single-mode or multimode fiber-optic cable in which each signal is assigned a different wavelength for its carrier wave; little space exists between carrier waves






49. A flexible communications cable that contains pairs of insulated copper wires that are twisted together for reduction of EMI and RFI and covered with an outer insulating jacket.






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