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 cable TV company - such as Comcast Broadband.






2. Helps you identify percentage of traffic that compromises broadcasts






3. Pulses of precise - positive voltages and zero voltages (binary)






4. Fiber Distributed Data Interface






5. Event that triggers alarms and causes an IDPS to react as if a real attack is in progress






6. The physical cables that link computers in a network






7. The process of connecting to a wireless network






8. The wave bounces back when encountering an object






9. Ppp over ethernet






10. Technology that uses standard telephone wires and allows transmission of voice and data information. Slower than ADSL.






11. Used to determine where patch cable for a specific server terminates on the patch panel - and checks for the presence of noise on a wire






12. Equivalent to OSI Layer 2 Data Link & Layer 1 Physical






13. IPX & SPX






14. Used by web browser and web servers to exchange files






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






16. 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






17. Facilities necessary for a service provider to connect with another organization LAN or WAN






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






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






20. Ensures outgoing traffic can traverse public networks by replacing each outgoing packets source addresss field w valid IP address






21. # of times that waves amplitude cycles - hertz






22. Not individually insulated but shielded. use when there is noise.






23. (fix) if analog shield twisted pairs or if digital with a repeater






24. Layer 3 Troubleshooting






25. A unit of data formatted for transmission over a network that contains control and other information that corresponds to the OSI Networklayer; also called Layer 3.






26. A transmission method that has distinct signal levels to represent binary zeroes or ones - such as +5 volts and 0 volts.






27. Signals travel in one direction






28. Allows for secure interactive control of remote systems






29. Prevents two nodes transmitting at the same time






30. 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.






31. Extent to which a signal has weakened after traveling a given distance






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






33. Modulation technique in which the amplitude of the carrier signal is modified by the application of a data signal






34. A network design built by running cable from one PC of file server to the next - like links in a chain.






35. The IEEE stanard for error and flow control in data frames.






36. A cable that consists of a single cable sheath containing a combination of fibers and copper cable.






37. The <html> - <head> and <body> tags are all examples of ________ tags






38. Also called coax - a network cable medium that consists of a copper core - surrounded by insulation.






39. RSA






40. Method of data modulation in which the frequency of the carrier signal is modified by the application of the data signal






41. Is a file transfer protocol that uses s ecure shell (SSH)






42. Lowest or 1st layer; protocols generate and detect signals so as to transmit and receive data over a network medium - also set the data transmission rate and monitor data error rates - but do not provide error correction






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






44. Aversion of the traceroute utility found on some Linux distributions.






45. Large diameter. led/light is generated at different angles. high throughput - high noise resistance - excellent security - and long distances






46. An advantage of networks






47. Style of data transmission in which the pulses that represent bits follow one another along a single transmission line; sequentially issued






48. Signals on bus that would travel endlessly between two nodes






49. Data jack
