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 unit of data transmitted on a network that contains control and address information corresponding to the OSI Data Link layer - or Layer 2.






2. Type of interference caused by signals traveling on nearby wire pairs infringing on another pair's signal






3. Form of transmission in which signals are modulated as radiofrequency analog pulses with different frequency ranges; does not involve binary coding






4. Application that will allow you to configure the workstation to tally these errors and send you and email message every time a problem occured






5. LC - ST - SC - or MT RJ






6. Network Access Layer






7. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






8. Which protocol is responsible for splitting data into packets and adding a header to each one?






9. 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






10. A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address - or vice versa. This is useful for verifying that a hos is configured correctly and for troubleshooting DNS resolution problems






11. 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.






12. Transmission that involves one transmitter and multiple - undefined receivers






13. 5th layer; establishes and maintains communication between two nodes on the network; 'traffic cop'






14. Secure Shell






15. An organization composed of more than 100 representatives from industry and government who together determine standards for the electronics industry in addition to other fields - such as chemical and nuclear engineering.






16. A transport system that uses the CSMA/CD access method for data transmission on a network. Typically it is implemented in a bus or star-bus hybrid topology.






17. Reverse address resolution protocol






18. Four twisted wire pairs rated for 250 MHz.






19. Wireless standard






20. TFTP - trivial file transfer protocol






21. 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.






22. Rules and configuration guidelines governing implementation and operation of IDPSs within an organization






23. 5 segments b/w two nodes - 4 repeating devices - and 3 segments connected by two repeating devices






24. A unit of data formatted for transmission over a network that contains control and other information that corresponds to the OSI Networklayer; also called Layer 3.






25. Data Link Layer






26. Communications cable that has no shielding material between the pair of insulated wires twisted together and the cable's outside jacket.






27. 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






28. Collection of honey pots connecting several honey pot systems on a subnet






29. The most popular type of network for medium- and large-scale organizations






30. A device used to connect thicknet cable with a transceiver. A vampire bypasses the need to serve the cable - because the vampire tap has a metal tooth that pierces through the outside cable insulation (like a vampire) and connects with the copper wir






31. Amplitude modulation-amplitude of signal is modified






32. FM






33. The cableing or radio waves used to connect one network computer to another - or one network to another - and transport data between them.






34. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet creation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






35. Electromagnetic interference






36. Core TCP/IP protocol that operates in the Network layer and provided information about how and where data should be delivered; subprotocol that enables TCP/IP to inernetwork






37. Hub/repeaters






38. GSNW






39. Translated network addresses into their physical counterparts






40. Data Link Layer






41. The oldest type of network design - this topology consists of multiple nodes attached to a central hub - switch - or router.






42. Allows clients to communicate in different floors






43. Eight bits of information; in a digital signaling system - one byte carries one piece of information






44. Allows for secure interactive control of remote systems






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






46. Connection based






47. Communications arrangement in which a single transmitter issues signals to multiple - defined recipients






48. The process of validating a user.






49. Max size of data units on Ethernet networks






50. IDPS that compares sampled network activity to established baseline
