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. BERT






2. A data communications technique that transmits a packet directly from the sending node - though a switch - and to the receiving node - without passing though other network nodes.






3. LC - ST - SC - or MT RJ






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






5. A gateway that operates on the Internet backbone.






6. Amount of data that can be transmitted over media or wireless at a time.






7. Transport Layer






8. 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.






9. Connection for data exchange between two parties






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






11. Network Layer






12. NLM






13. Translates data to a format the receiving node understands - such as from EBCDIC to ASCII - Performs data encryption - Performs data compression






14. A type of transmission in which there are several transmission channels on a communications medium - allowing more than one node to transmit at the same time.






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






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






17. 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






18. Tool used to determine whether a customers line is obtaining dial tone from the CO






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






20. CDFS






21. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






22. Lower sublayer of the Data Link layer; appends the physical address of the destination computer onto the fram






23. A generic term referring to the header defined by some layer of a networking model - and the data encapsulated by the header ( and possibly trailer) of that layer - but specifically not including an lower-layer headers and trailers.






24. 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.






25. What is the term used when every host on the network has a fixed IP address?






26. An established guidline that specifies how networked data is formatted into packet or frame - how it is transmitted - and how it is interpreted at the receiving end.






27. Helps you identify percentage of traffic that compromises broadcasts






28. Doesn't use frame headers - uses cells






29. Device that separates broadcast domain






30. BDC






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






32. IRC






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






34. Routing protocol has the poorest convergence time






35. The number of times a signal's amplitude changes over a fixed period of time - expressed in cycles per second - Hz






36. PPP






37. Packet






38. 12 digits - A-F/0-9






39. ADSL






40. Transforms data into a form network or applications will understand






41. TFTP is a TCP/IP file transfer protocol that is designed for task such as the transfer of data to enable a diskless workstation to boot using files trasmitted from a server






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






43. On a computer that receives data over a network - the process in which the device interprets the lower-layer headers and - when finished with each header - removes the header - revealing the next-higher-layer PDU.






44. A specialized device that allows multiple networks or segments to connect and exchange data






45. Internet Engineering Task Force






46. An advantage of networks






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






48. Application layer protocol used to access information stored in a directory






49. Serial internet protocol






50. IEEE standard for Ethernet devices and data handling
