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 wave splits into secondary waves






2. Unwanted signals from sources near network cabling - such as motors and power lines






3. Domain Name System






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






5. SONET






6. Field in a frame responsible for ensuring that data carried by the frame arrives intact. Uses an algorithm - such as CRC - to accomplish verification






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






8. IEEE 802.2 Logical Link Control (LLC) sublayer of the data link layer

10. FTP-Data - file transfer data






11. Open Systems Interconnection model is standard description or reference model for how messages should be transmitted between any 2 points in a telecommunications network.






12. ISDN






13. Data Link Layer






14. Routing protocol has the poorest convergence time






15. Only two wire pairs are reversed






16. A digital communication service that uses the same network infrastructure as PSTN - but is expensive






17. A Data Link sublayer that examines addressing information contained in a network frame and controls how devices share communications on the same network.






18. Nondata information that mus accompany data in order for a signal to be properly routed and interpreted by the network






19. Multiplexing based on priority






20. Is part of theTCP/IP protcol suite and used to retrive e-mail from a remote server to a local client over a TCP/IP connection






21. Fiber-optic cable used on a network backbone for high-speed communications - such as between floors of a building.






22. HTTP/web/internet - change this port to make it more difficult for someone to connect to your web server






23. Gives each node unique address






24. An international organization of scientists - engineers - technicians - and educators that plays a leading role in developing standards for network cabling and data transmissions.






25. 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.






26. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






27. A computer (mainframe - minicomputer - server - or workstation) that has an operating system enabling multiple computers to access it at the same time for files - data - and services.






28. RADIUS






29. A network design consisting of a continuous path for data with no logical beginning or ending point - and thus no terminators.






30. A Data Link sublayer of the OSI model that initiates the communication link between nodes and ensures the link is not unintentionally broken.






31. FHSS






32. Secure Sockets Layer






33. When pulses that represent bits follow one another along a single transmission






34. Hypertext Transfer Protocol






35. Theoretical. difference b/w highest and lowest frequency.






36. Strength of digital signal






37. Radio frequency interference






38. ACL






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. Network configuration that allows selected outside organizations to access internal information systems.






41. Application Layer






42. Session Layer






43. Data jack






44. 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






45. A term used to refer to data within the Data-link layer of the OSI model.






46. Manages end-to-end delivery of data






47. CNAME






48. NLM






49. An IDPS that resides on particular computer or server (the host) and monitors activity only on that system. Also known as system integrity verifiers.
