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. Issue signals along a network medium






2. A type of multimode fiber-optic cable in which the light-based signals follow uniform curved routes inside the cable - resulting in signals that all arrive at the same time and with less long-distance distortion than step-index cable.






3. A single physical/non-physical medium for connecting computers






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






5. Layer 2 Troubleshooting






6. After typing ping 127.0.0.1 - it tells you the test failed






7. Brief delay in processing - length of cable can contribute to this






8. 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.






9. Allows an attached computer to act as a dumb terminal - with data processing taking place on the TCP/IP host computer






10. A connector used to terminate coaxial cable used for transmitting television and broadband cable signals






11. A computer that accesses another computer - such as a workstation that accesses a shared file on another workstation - server - or mainframe. The client may use the accessed computer (host) to process data - or may process accessed data using its own






12. The shorter the wavelength






13. 128-191






14. Unique identifying number for a network node; follows a hierarchical addressing scheme; can be assigned through OS software; added to data packets and interpreted by protocols at the Network layer






15. Distance between corresponding points on cycle






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






17. MSAU






18. Set of protocols that specify how wireless networks works. Most common are currently B and G. N is an emerging standard.






19. Routes packets through network






20. More variable - convey greater subtleties with less energy






21. Networking technology developed by IBM in the 80s; relies upon direct links between nodes and ring topology - using tokens to allow nodes to transmit data






22. 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






23. 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.






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






25. Hardware that constitutes the enterprise-wide cabling system






26. (fix) if analog an amplifier or if digital with repeater






27. The process of connecting to a wireless network






28. PPP






29. IEEE






30. Address resolution protocol






31. Device that processes signals; multiplexer or modem






32. Pointing in a direction






33. Open System Interconnection






34. Packet






35. Used by web browser and web servers to exchange files






36. Local area network






37. Hardware device typically used to connect multiple LANs






38. Provides FTP - HTTP - SMTP...






39. 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






40. Multiplexing based on priority






41. User datagram protocol






42. A network that links multiple LAN's in large city or metropolitan region.






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






44. Layer 3 Troubleshooting






45. 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






46. Short reach. only multimode-max length is 500. baseband transmission. 1000 mpbs.






47. Uses frame headers






48. A gateway that operates on the Internet backbone.






49. A data link protocol used for remote networking that is rarely used today.






50. Electromagnetic interference
