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 type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.






2. Different upload/download speeds.






3. Type of sensor deployed in such a way that the network traffic it is monitoring must pass through it.






4. Frequency modulation-frequency of signal is modified






5. Device that processes signals; multiplexer or modem






6. A connecting device for a network that accepts messages and broadcasts them out to the rest of the network.






7. Twisted pair cable consisting of a number of twisted pairs of copper wire with a simple plastic casing. Because - no shielding is used in this cable - it is very susceptible to EMI - RFI - and other types of interference






8. Multiple signals travel simultaneously - medium is separated into multiple channels






9. LPD






10. Uses multiple frequencies to transmit signal






11. Is usde to communicate time synchronization information between systemson a network






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






13. The communication between two networking devices for the purposes of the functions defined at a particular layer of a networking model - with the communication happening by using a header defined by that layer of the model. The two devices set values






14. FDDI






15. On a computer that receives data over a network - the process in which the device interprets the lower-layer headers and - when finished with each header - removes the header - revealing the next-higher-layer PDU.






16. Open source program that allows you too remotely take over another workstation and walk through support process






17. NLM






18. Measure of the difference between the highest and lowest frequencies that a medium can transmit






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






20. Upper sublayer in the Data Link layer. Provides a common interface and supplies reliability and flow control services






21. Constructs data frames using the appropriate format for the network - reatea CRC information - Checks for errors using CRC information - Retransmits data if there is error - Initiates the communications link and makes sure it is not interrupted - thu






22. A computer that provides client stations with access to files and printers as shared resources to a computer network






23. A utility for viewing or modifying a host's routing table






24. 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.






25. NTP






26. A high-capacity communications medium that joins networks on the same floor in a building - on different floors - and across long distances.






27. Physical Layer






28. CIFS






29. BRI






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






31. A worldwide network of interconnected LANs and MANs that uses the TCP/IP protocol to enable people to shares e-mail messages and computer files and to access a vast array of information.






32. Single mode fiber






33. RAS






34. 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.






35. Hubs and switches work here






36. An established guideline that specifies how networked data is formatted into a packet or frame - how it is transmitted - and how it is interpreted at the receiving end.






37. Layer 1 Troubleshooting






38. Telnet






39. Connector with 9 pins - commonly used in a serial communication that conforms to the rs-232 standard






40. IANA






41. NDS






42. 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).






43. 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.






44. Application layer protocol used to access information stored in a directory






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






46. American national standards institute






47. A private computer network with resources accessible only to internal members.






48. The process of attracting attention to a system by placing tantalizing information in key locations.
