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. Delay between the transmission of a signal and its receipt






2. An international organization of scientists - engineers - technicians - and educators that plays a leading role in developing standards for network cabling and data transmissions.






3. Asynchronous digital subscriber line. Method of providing internet service that uses the standard phone line - but transmits data at a different frequency than voice. Faster than ISDN.






4. Uses frame headers






5. Physical Layer






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






7. Voltage is varied and imprecise - more susceptible






8. Layer 2 Troubleshooting






9. Physical layer. 10 giga bit throughput. baseband transmission. twisted pair. max length is 100 meters. cat 6 or 7.






10. GPO






11. Application Layer






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






13. Control frame that indicates to the rest of the network that a particular node has the right to transmit data






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






15. Method of error checking that determines if the contents of an arriving data unit match the contents of the data unit sent by the source






16. A connecting device for a network that accepts messages and forwards them to the correct section of the network. Generally more intelligent than a hub and a switch.






17. Term that describes current anti-intrusion technologies






18. A TCP/Ip troubleshooting utility that displays statistics and the state of current TCP/IP connections. It also displays ports - which can signal whether services are using the correct ports.






19. 192-223






20. Each node passively listens for then accepts data






21. Multiplexing based on priority






22. Computers connected together within a limited geographical area






23. MAC Protocols






24. NLM






25. Follow TIA/EIA 568 specifications






26. DNS - Domain name system






27. Which address is split in to four 8-bit parts called octets?






28. MDI






29. Layer 5






30. Application Layer






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






32. Logical link control






33. A coaxial connector uses a twist and lock style - may be used with Rg-6 and RG-59






34. A fiber-optic data transport method capable of a 100-Mbps transfer rate using a dual ring topology; largely supplanted today by faster Ethernet method.






35. FM






36. Does not operate at the application layer






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






38. A combination of techniques used to detect an intrusion and then to trace it back to its source






39. Frequency hoping spread spectrum: a signal jumps between several different frequencies






40. A network owned and maintained by an organization -such as a campus network operated by a college.






41. The <html> - <head> and <body> tags are all examples of ________ tags






42. Scrambles information into an alternative form that requires a key or password to decrypt the information.






43. Fiber-optic cable used on a network backbone for high-speed communications - such as between floors of a building.






44. A group of two or more computer systems linked together.






45. 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).






46. Trivial file transfer protocol






47. 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 stop. Aborbing the signals ensures they are not reflected back onto the cable after they reach the end-t






48. Type of sensor deployed in such a way that the network traffic it is monitoring must pass through it.






49. A term used to refer to data within the Data-link layer of the OSI model.






50. Techniques that employ hardware and software to provide assurance against equipment failures - computer service interruptions - and data loss.
