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. Physical Layer






2. Slow wireless standard 11-18 throughput






3. 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.






4. Multiplexing based on priority






5. The physical cables that link computers in a network






6. Physical Layer






7. Digital subscriber line- support multiple data and voice channels over a single line - extraordinary throughput though telephone lines






8. An internetwork is two or more computer networks connected together.






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






10. Http - Hypertext transfer protocol






11. 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






12. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet genation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






13. Medium network 128-191






14. A technique for transmitting data over a network by encapsulating it within another protocol.






15. Type of interference that may be caused by motors - power lines - televisions - copiers - etc






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






17. Is a protocol for defining host groups.






18. Process in which an NIDPS inspects the higher-order protocols (HTTP - FTP - Telnet) are examined for unexpected packet behavior or improper use






19. The process of wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer. For example - Data Link layer protocols encapsulate Network layer packets in frames.






20. A type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.






21. 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






22. Packet a node sends to acknowledge that it received a SYN request for connection; 2nd of three-step connection process






23. Translated network addresses into their physical counterparts






24. A utility for viewing or modifying a host's routing table






25. 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.






26. Manages network communication - available on a CD-ROM for example - that is used to manage communications and how frames or packets are sent using a protocol.






27. Device that enables networks or segments using different media to interconnect and exchange signals






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






29. Performs name resolution






30. An organization composed of more than 100 representatives from industry and government who together determine standards for the electronics industry in addition to other fields - such as chemical and nuclear engineering.






31. Distinct communication path between two or more nodes; may be separated logically or physically






32. SFTP






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






34. SCP






35. Network news transfer protocol






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






37. A network that any user can access with no restrictions. the most familiar example of a public network is the Internet






38. Which class of IP address would be allocated to a very large company?






39. Service data unit






40. NLM






41. What does POP3 stand for?






42. Device that modulates analog signals into digital signals for transmission over telephone lines - and demodulates digital signals into analog for the receiving end






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






44. Ethernet NICs listen on network and wait until they detect no other nodes transmitting data






45. A network design in which every node is connected to every other note - achieving fault tolerance.






46. SLIP






47. Single mode fiber






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






49. 4th layer; protocols ensure that data are transferred from point A to point B reliably and without errors; services include flow control - acknowledgment - error correction - segmentation - reassembly - and sequencing






50. A type of subnet that is created using bits that normally would be reserved for network class information by moving the subnet boundary to the left.
