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






2. The NIC and network equipment are set up so they cannot send and receive at the same time






3. A station checks for existing wireless transmissions before starting the transmission






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






5. 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






6. # of times that waves amplitude cycles - hertz






7. (local area network) network of computers and others that is confined to a relatively small space






8. Style of data transmission in which the pulses that represent bits follow one another along a single transmission line; sequentially issued






9. The wave splits into secondary waves






10. Also called the star-bus hybrid topology - a network design that combines the logial comunications of a bus with the physical layout of a star.






11. Layer 1






12. Controls how applications access network






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






14. Device that connects network segments and directs data based on information in the data packet






15. Provides th transfer medium (such as cable) - Translates data into a transmission signal appropriate to the transfer medium - Sends the signal along the transfer medium - Includes the pyical layout of the network - Monitors for transmission error - D






16. RDP






17. HDLC






18. One transmitter issues signals to multiple receivers; receivers may be undefined or defined






19. Event that triggers alarm when no actual attack is in progress






20. 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






21. Which layer in the OSI network model is responsible for providing a set of interfaces for applications to obtain access to networked services?






22. Prevents two nodes transmitting at the same time






23. Facilities necessary for a service provider to connect with another organization LAN or WAN






24. Twist wire so you don't get interference on the memory






25. Enables sharing remote drivers - Enables sharing remote printers - Handles e-mail messages - Provides file transfer services - Provides file management services - Provides terminal emulation






26. Issue signals along a network medium






27. Each node is connected to the two nearest nodes so that the entire network forms a circle - active - twisted pair of fiber optic - single malfunction in workstation can disable entire network - not flexible or scalbe






28. What is an agreed set of rules that two parties agree on in order to communicate with each other commanly known as?






29. RAS






30. Software that is stored on a chip in a device - such as in a ROM - and that typically composes some type of system software






31. Uses light to communicate a signal; the light is dispersed on numerous paths as it travels through the core and is reflected back. Provides high bandwidth at high speeds over medium distances up to about 3000 feet






32. Amplitude - frequency (Hz) - wavelength - wavy line






33. The process of enclosing data for transmission






34. Similar to FTP. lets you transfer files between a host and an FTP server






35. The process of reconstructing segmented data






36. NAT






37. Unit of data at any layer of the OSI model






38. PAP






39. Scrambles information into an alternative form that requires a key or password to decrypt the information.






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






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






42. CHAP






43. Similar to bus topology - but the ends are connected






44. Institute of electrical and electronics engineers






45. Data Link Layer






46. Error detection and correction






47. Response generated atTransport layer confirming to sender that its frame was received; 3rd step in establishing a connection






48. 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






49. A physical layer standard that defines a method for building a synchronous telecommunications network based on fiber-optic cables.






50. The Application layer TCP/IP subprotocol responsible for moving messages from one e-mail server to another.
