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. Unit of data at any layer of the OSI model






2. Addresses packet size






3. Speed: 10 Mbps - Alternative Name: 10BASE-T - IEEE Standard: IEEE 802.3 - Cable Type: Copper - max length 100 meters






4. SMTP - simple mail transfer protocol






5. Layer 2 Troubleshooting






6. Equivalent to OSI Layer 7 Application - Layer 6 Presentation - Layer 5 Session






7. An app. that provides centralized authentication and authorization services for a network.






8. Type of transmission in which signlas may travel in both directions over a medium - but only in one direction at a time






9. Glass or plastic shield around the core of a fiber-optic cable; reflects light back to the core in patterns that vary depending on the transmission mode






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






11. An algorithm used to verify the accuracy of data contained in a data frame.






12. Layer 1 Troubleshooting






13. The process of checking a communication medium - such as cable - for a voltage level - signal transition - or light - indicating the presence of a data-carrying signal.






14. A type of cabling that includes pairs of copper conductors - twisted around each other - inside a metal or foil shield. This type of medium can support faster speeds than unshielded wiring






15. Offers one way for a computer to access another computer over the network or over the Internet. For example - an IBM programmer can use Telnet on a Windows XP or Red Hat Enterprise Linux computer to access a mainframe though the Internet






16. Lower sublayer of the Data Link layer; appends the physical address of the destination computer onto the fram






17. Data changed since the previous fill or incremental backup






18. Cause by length - loss of signals as it travels farther away






19. Device that can detect intrusion and launch an active response






20. Resistance that contributes to controlling an electrical signal; measured in ohms






21. Voltage is varied and imprecise - more susceptible






22. International Organization for Standardization






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






24. 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






25. RJ 45






26. Is a secure form of HTTP






27. Layer 7






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






29. The IEEE standard for token ring networking devices and data handling.






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






31. Wide area network






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






33. Communications cable that consists of one or more glass 0r plastic fiber cores inside a protective cladding material - covered by a plastic PVC outer jacket. Signal transmission along the inside fibers typically uses infrared light.






34. Physical Layer






35. Physical layer. 1 gpbs throughput. baseband transmission. max length is 100 meters. cat 5e or higher utp. twisted pair.






36. Open Systems Interconnection model






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






38. Institute of Electrical and Electronics Engineers






39. SCP






40. Accurate alarm events that do not pose significant threat to information security






41. The device inside a computer that connect a computer to the network media






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






43. Max size of data units on Ethernet networks






44. Encompasses actions an organization takes when intrusion is detected






45. 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






46. Data only






47. Internet Layer






48. IEEE standard for token ring devices and data handling






49. For fiber-optic cable communications - the difference between the transmitted power and the receiver sensitivity - as measured in decibels. It is the minimum transmitter power and receiver sensitivity needed for a signal to be sent and received fully






50. An IP addressing convention that adheres to network class distinctions - in which the first 8 bits of a Class A address - the first 16 bits of a Class B address - and the first 24 bits of a Class C address are used for network Information
