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. Device that processes signals; multiplexer or modem






2. 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






3. 128-191






4. Internet society






5. AMI






6. Addresses packet size






7. Tracks running and graphing data from any workstations. should ensure that new routers and switches can support it in order to easily automate network management






8. Device that separates multiplexed signals once they are received and regenerates them in their original form






9. IPX






10. Frequency modulation-frequency of signal is modified






11. Network interface card






12. Length of time it takes for a packet to go from sender to receiver - then back to sender; measured in milliseconds






13. Large networks 1-126






14. An enclosed area - such as a false floor - or ceiling - in which pressure from air or gas can be greater than the pressure outside the enclosed area - particularly during a fire. Plenum area in buildings often extend to multiple rooms or extend throu






15. The most commonly used form of Post office protocol.






16. Divides channel into different time slots and assigns data to nodes who are attached to time slots






17. A mail retrieval protocol that improves on the shortcomings of POP. The single biggest advantage IMAP4 has relative to POP is that it allows users to store messages on the mail server - rather than always having to download them to a local machine.






18. LLC






19. Binary values for each bit position






20. Point to point protocol






21. A device that must be located at each end of a leased line.






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






23. 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






24. Device that modulates analog signals into digital signals for transmission over telephone lines - and demodulates digital signals into analog for the receiving end






25. F type (like TV cable) or BNC (crimped)






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






27. Connection based






28. Extended service set: a group of access points






29. A type of point-to-point digital WAN connection that uses standard phone lines to provide high-speed comm.






30. RDP






31. Each computer is connected to a central device






32. Wireless standard






33. Rules determining the format and transmission of data






34. Process by which attacker changes the format and/or timing of their activities to avoid being detected by the IDPS






35. Process of adjusting IDPS to maximize efficiency in detecting true positives - while minimizing false positives and false negatives






36. Bus topology: A network design built by running cable from one PC or file server to the next - like links in a chain.






37. Port used during a domain name lookup






38. 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.






39. A type of address translation in which a limited pool of internet-valid IP addresses is shared by multiple private network hosts.






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






41. NLM






42. Can use WPA to improve the security of data in transit






43. As defined by the EIA/TIA-568 standard - cable that runs between network equipment rooms - floors - and buildings.






44. Braided metal shielding used to insulate some types of coaxial cable






45. Application Layer






46. Direct-sequence spread spectrum: signal bits are distributed over a frequency band






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






48. Four twisted wire pairs rated for 100 Mhz.






49. Ppp over ethernet






50. Speed: 100 Mbps - Alternative name: 10BASE-TX - IEEE Standard: IEEE 802.3u - Cable Type: Copper - max length 100m
