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






2. Protocol that encapsulates data for transmission over VPNs






3. A versatile - chainable serial-bus technology that connects up to 127 devices at speeds of 1.5 Mbps and 12 Mbps as well as 480 Mbps.






4. Application Layer






5. A data encryption technique employed between a server and a client - such as between a client's browser and an Internet server.






6. Issue signals along a network medium






7. The general topic of how on one computer - two adjacent layers in a networking architectural model work together - with the lower layer proving services to the higher layer.






8. 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






9. Specify clients configurations to adhere to this subnet






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






11. The organized research of the Internet addresses owned or controlled by a target organization.






12. Progress of a wave over a time in a relationship






13. 4th layer; protocols ensure that data are transferred from point A to point B reliably and without errors; services include flow control - acknowledgment - error correction - segmentation - reassembly - and sequencing






14. The process of enclosing data for transmission






15. Strength of digital signal






16. RJ 45






17. A private network that functions like a tunnel through a larger network






18. Consists of activities that deter intrusion






19. 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






20. Type of punch-down block used to terminate telephone circuits; does not meet Cat 5 or better standards






21. A series of interconnected computers - printing devices - and other computer equipment that shares hardware and software resources. The service area usually is limited to a given office area - floor - or building.






22. Power loss - the amount of signal that is lost as it travels though the communication medium from the source (transmitting node) to the receiving node.






23. Package for data that includes not only the data - or 'payload -' but also the sender's and recipient's addressing and control information. Generated at the Data Link layer and issued to the Physical layer






24. Any device connected to a network - such as a microcomputer - mainframe - midrange computer - network equipment - or printer. Also called a station.






25. Term that describes current anti-intrusion technologies






26. This layer in the OSI network model breaks up the files into packets to allow them to be sent around the network.






27. Network news transfer protocol






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






29. A standard for encoding and interpreting binary files - images - video - and non-ASCII character sets within an e-mail message.






30. Physical Layer






31. Max size of data units on Ethernet networks






32. Basic service set: a group of stations that share an access point






33. 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 stops. Absorbing the signals ensures they are not reflected back onto the cable after they reach the end






34. Logical link control






35. A value or means of identifying a service on a network node - such as socket or port 103 for standerdized e-mail services in the TCP protocol.






36. 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.






37. The actual data - any communication that encodes a message






38. A device that can transmit and receive - such as transmitting and receiving signals on a communication cable






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






40. Connection-less






41. 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.






42. 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.






43. (metropolitan area network) used with a handful of buildings and larger then a LAN - connects two or more Lans






44. Occurs when attacker attempts to gain entry or disrupt normal operations of information systems - almost always with intent to do harm






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






46. Stop signals after they have reached the end of the wire






47. The more resistant to cross talk (STP)






48. Method of controlling how network nodes access communication channels - ex highway






49. Signals traveling on one wire infringes on the signal traveling over an adjacent wire






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