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






2. Digital - one signal one channel at a time (half duplexing) ex. ethernet






3. Provides services for applications






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






5. Consists of activities that deter intrusion






6. Associates a MAC address with a given IP address - reverse ARP






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






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






9. A physical layer standard that defines a method for building a synchronous telecommunications network based on fiber-optic cables.






10. Multimode fiber






11. Type of multiplexing that assigns a unique frequncy band to each communications subchannel






12. Reverse address resolution protocol






13. Form of transmission that allows multiple signals to travel simultaneously over one medium






14. IDPS that reviews log files from servers - network devices - and other IDPSs for signatures indicating an attack or intrusion






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






16. The medium that carries multiple signals simultaneously






17. A remote connection where the client computer is a low-end computer that communicates with a terminal server.






18. Process of directing a datagram from its source through an internetwork to its destination using the most efficient path.






19. Voltage is varied and imprecise - more susceptible






20. CHAP






21. IPv6 addressing - multicast group






22. Is associated with unix/linux networks






23. Supplying electrical power through ethernet






24. A standard for encoding and interpreting binary files - images - video - and non-ASCII character sets within an e-mail message.






25. Data only






26. Also called the physical or MAC address - the hexadecimal number permanently assigned to a network interface and used by the MAC sublayer within the DATA Link layer (Layer 2).






27. Used to resolve NetBIOS names w IP address






28. The process of reconstructing segmented data






29. Round time trip. time it takes for packet to get from sender to receiver and back






30. OTDR






31. PAP






32. 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 stop. Aborbing the signals ensures they are not reflected back onto the cable after they reach the end-t






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






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






35. Unix command at shell prompt to send a file to printer






36. Is used to enable IP address to be assigned automatically by a DHCP server on a network.






37. Software that is stored on a chip in a device - such as in a ROM - and that typically composes some type of system software






38. Electronics industries Alliance






39. Segment






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






41. 2nd set of characteristics that make up a device's MAC address. Added at the factory and is based on the device's model and manufacture date






42. All wires are reversed






43. A generic term referring to any set of protocols and standards collected into a comprehensive grouping that - when followed by the devices in a network - allows all the devices to communicate. Examples include TCP/IP and OSI.






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






45. Logical link control






46. 3rd layer; protocols translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver






47. Requires many pulses to transmit same info that an analog can transmit in a wave






48. Netscape and Microsoft have implemented HTTPS to protect data transported via their Web browsers.






49. Equivalent to OSI Layer 4 Transport






50. Device that receives and retransmits microwave data signals
