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. The distinct units of data that are exchanged between nodes on a network






2. Cross talk with 2+ wires






3. 6th layer; protocols translate between Application and Network layers; data are formatted so that the network can understand - with the format varying according to the type of network; manages data encryption and decryption - such as scrambling of sy






4. String used to identify an access point - configure on your new access points to match the settings on existing access points






5. Fiber optic - enables one fiber optic connection to carry multiple light signals simultaneously






6. Source emits a RTS (request to send) signal to the access point - and the access point replies with CTS (clear to send) for the source to begin its transmission






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






8. A cable that consists of a single cable sheath containing a combination of fibers and copper cable.






9. (WIde area network) Carry networks longer distances than Lans






10. Transport Layer






11. Every node on the network is connected through a central device like a switch - cannot be disabled by a single malfunction in a workstation - scalable - - popular - expensive - cable malfunction will only effect 2 workstations - more fault tolerant.






12. A data communications technique that transmits a packet directly from the sending node - though a switch - and to the receiving node - without passing though other network nodes.






13. 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).






14. Is a system that is distributed throughout the internetwork to provide address/name resolution.






15. Each computer is connected to a central device






16. Layer 3 Troubleshooting






17. Twisted pair patch cable in which the termination locations of the transmit and receive wires on one end of the cable are reversed






18. Transport protocol and TCP/IP port that uses telnet utility use






19. NCP






20. A system of computers - print devices - network devices - and computer software linked by communications cabling or radio waves.






21. Attachment Unit Interface Cable equipped with 15 pin connectors






22. OU






23. FM






24. The seventh layer of the OSI model. Application layer protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network.






25. 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.






26. Measure of a signal's strength






27. Provides a generic method of transferring files






28. Hardware device located at the ISP side of ADSL connections.






29. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






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






31. Device used to regenerate a signal






32. AFP






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






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






35. Equivalent to OSI Layer 3 Network






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






37. 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






38. Secure Hypertext Transfer Protocol






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






40. Also called coax - a network cable medium that consists of a copper core - surrounded by insulation.






41. MDI






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






43. Network cable that contains pairs of insulated wires that are twisted together and surrounded by a shielding material for added EMI and RFI protection - all inside a protective jacket.






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






45. Guarantees that a server continually has power even if a buildings electrical service is interrupted - continuous voltage to a device by switching virtually instantaneously to the battery when it detects loss of power






46. Strategy that combines the best of the other two strategies; while individual agents still analyze and respond to local threats - their reporting to a hierarchical central facility enables the organization to detect widespread attacks






47. Which address is split in to four 8-bit parts called octets?






48. Glass or plastic shield around the core of a fiber-optic cable; reflects light back to the core in patterns that vary depending on the transmission mode






49. Defines host IP in packet headers






50. Faster networking and inexpensive - flexible - easy to install
