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. First set of six characters that make up the MAC address and that are unique to a particular manufacturer






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






3. Device that enables networks or segments using different media to interconnect and exchange signals






4. PRI






5. Also called the physical or device address - the hexadecimal number permanently assigned to a network interface and used by the MAC sublayer within the DATA Link layer (Layer 2).






6. Communications that occur in discrete units where the start of a unit is signaled by a start bit at the front and the end of the unit is signaled by a stop bit at the back.






7. Frequency modulation-frequency of signal is modified






8. Extended service set: a group of access points






9. NIDPS system that examines network traffic in order to identify problems related to the flow of traffic. Most sensors are passive mode deployment only.






10. Media Access Unit (transmitter/ receiver)






11. The process in which an attacker obtains confidential information by contacting employees and deceiving them into giving up passwords - IP addresses - server names - and so on.






12. OTDR






13. Saturation of network bandwidth caused by excessive traffic - as when a large number of computers or devices attemp to transmit simultaneously - or when computers or devices presist in transmitting repeatedly.






14. A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility - but provides more information - even in its simplest form - than nslookup can.






15. Device that acts as a wireless switch so that nodes can connect wirelessly to a network.






16. A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't - the one carrying a signal will induce a 'ghost' signal in the other cable






17. The most widely-used protocol that manages notes posted on usenet newsgroups






18. GSNW






19. Useful for troubleshooting a network connectivity problem from workstation to another workstation






20. Service that supports email






21. A far-reaching system of networks that usually extends over approximately 48 kilometers (about 30 miles) and often reaches across states and continents.






22. Amplitude modulation-amplitude of signal is modified






23. Wavelength division multiplexing






24. 185 meters - 10Mbps






25. Technique for formatting signals in which one property of a carrier wave is modified by the addition of a data signal during transmission






26. Doesn't use frame headers - uses cells






27. Public switched telephone network






28. Has 25 pins also commonly used with serial communication that conforms to the rs-232 standard






29. IEEE standard for wireless networking






30. Bootstrap Protocol






31. A very high speed - long distance media that consists of a single strand of fiber glass that carries the signals. Can transmit data 50 times further than multimode fiber at a faster rate






32. Defines host IP in packet headers






33. Electromagnetic interference






34. Institute of electrical and electronics engineers






35. An authentication protocol that uses public key technology to provide users with secured access to network resources.






36. Decreasing the size of data units when moving data from a network that can handle larger units to one that can handle only smaller units






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






38. The medium that carries multiple signals simultaneously






39. Domain Name System






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






41. A cable that consists of a single cable sheath containing a combination of fibers and copper cable.






42. Ethernet communications at speeds up to 100 Mbps as defined under the IEEE 802.3u standard.






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






44. Network time protocol






45. Most resistant to EMI






46. Specify clients configurations to adhere to this subnet






47. Is a protocol for defining host groups.






48. Controls how applications access network






49. A type of multimode fiber-optic cable that reflects the light-based signals like a mirror within the cable - resulting in different signals arriving at different times and with an increased likeihood of distortion over longer cable runs.






50. Uses multiple frequencies to transmit signal
