IT: Networking Vocab

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.

8. Progress of a wave over a time in a relationship






9. Media access control






10. Groups of workstations are star connect to connectivity devices and then networked via single bus - cover long distances - easy to interconnect - more expensive - ethernet






11. A protocol data unit that has been transfered between OSI layers and then stripped of control information and transfere instructions.






12. Equivalent to OSI Layer 3 Network






13. Communications for continuous burst of data controlled by a clock signal that starts each burst.






14. Prevents two nodes transmitting at the same time






15. Glass/plastic - light pulses high throughput - resistant to noise - most expensive cable






16. Routing protocol has the poorest convergence time






17. RJ 11






18. A cable TV company - such as Comcast Broadband.






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






20. Security for https://






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






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






23. What type of browser is designed for use on small handheld devices such as palmtop computers and iPhones?






24. Physical layer. 100 mpbs throughout. baseband transmission. cat 5 or higher utp. max length is 100 meters. two wire twisted pair-full duplexing.






25. Is usde to communicate time synchronization information between systemson a network






26. Power loss - the amount of signal that is lost as it travels though the communication medium from the source (transmitting node) to the receiving node.






27. The device inside a computer that connect a computer to the network media






28. Control frame that indicates to the rest of the network that a particular node has the right to transmit data






29. Braided metal shielding used to insulate some types of coaxial cable






30. A device that can transmit and receive - such as transmitting and receiving signals on a communication cable






31. The most popular type of network for medium- and large-scale organizations






32. Stop signals after they have reached the end of the wire






33. Describes a theoretical representation of what happens between two nodes communicating on a network






34. Backbone: A high-capacity communications medium that joins networks on the same floor in a building - on different floors - and across long distances.






35. Open System Interconnection






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






37. Used to log on to a UNIX host






38. Data jack






39. Helps you identify percentage of traffic that compromises broadcasts






40. The physical layout of a computer network






41. NIS






42. Networking technology developed at Xerox in the 70s and improved by Digital Equipment Corp - Inel - and Xerox. Most common form of network transmission - follows IEEE 802.3 standard






43. OSPF






44. A poplar alternative to FTP is NFS software offered by Sun Microsystems - which uses Sun's remotr procedure call specification via TCP port 111.






45. Method of controlling how network nodes access communication channels - ex highway
