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. Reverse address resolution protocol






2. Satellite used for broadband internet access






3. Secure Sockets Layer






4. A connecting device for a network that accepts messages and forwards them to the correct section of the network. Generally more intelligent than a hub and a switch.






5. A connecting device for a network that accepts messages and passes them on to other parts of the network. Generally more intelligent than a hub.






6. What is a unique name that identifies an internet site called?






7. Length of time it takes for a packet to go from sender to receiver - then back to sender; measured in milliseconds






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






9. Any end device on the network (for example: computers - printers - copy machines...)






10. Establishes maintains and terminates connections






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






12. The sender transmits the data to the destination without establishment of a connection.






13. Computers connected together within a limited geographical area






14. Type of protocol useful when data must be transferred quickly






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






16. The shorter the wavelength






17. Speed: 100 Mbps - Alternative name: 10BASE-TX - IEEE Standard: IEEE 802.3u - Cable Type: Copper - max length 100m






18. Assigning a unique frequency band to each communication






19. Firewall packet inspection that examines the data contained in a packet as well as the state of the connection between internal and external computers.






20. Most common cabling used in networking. Usually connects nodes to the main network.






21. Radio frequency interference






22. IDPS's ability to dynamically modify its configuration in response to environmental activity






23. The ability to send or receive signals on a medium - but not at the same time.






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






25. Type of transmission in which signals may travel in both directions over a medium simultaneously; also called duplex






26. Total amount of communication cable that make up a network.






27. Carrier sense multiple access w collision detection (network access method) ethernet






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






29. Begins when a system that initiated the connection transmits a PPP frame.






30. Techniques that employ hardware and software to province assurance against equipment failures - computer service interruptions - and data losses






31. Point of division between a telecommunications service carrier's network and a building's internal network






32. A computer on a network that requests services or resources from another computer on a network






33. Feeding everybody in building






34. MMF






35. Each node passively listens for then accepts data






36. ADSL






37. Routers work here






38. 128 -64 -32 -16 -8 -4 -2 -1






39. Routing protocol has the poorest convergence time






40. Unit of data that results from subdividing a larger protocol data unit






41. Internet assigned numbers authority






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






43. Type of switching for multiple data packets make up the same transmission and use identical paths to reach the destination






44. Defines host IP in packet headers






45. A permanent telephone connection between 2 locations that provide a predetermined amount of bandwidth at all times






46. A logical process of combining bits. In ANDing - a bit with a value of 1 plus another bit with a value of 1 results in a 1. A bit with a value of 0 plus any other bit results in a 0.






47. Provides Internet access and/or other services such as email and Web hosting






48. ACL






49. It enables the sending node to obtain the MAC address of the intended recipient before packets are sent.






50. IEEE
