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.

4. 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.






5. Defines the physical characteristics of the network






6. More reliable then analog - noise doesn't affect as much - more efficient - fewer errors






7. Electromagnetic interference






8. An international organization of scientists - engineers - technicians - and educators that plays a leading role in developing standards for network cabling and data transmissions.






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






10. 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.






11. Services that allow remote users to connect to the network






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






13. The action of luring an individual into committing a crime.






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






15. Method of trasmitting data from a satellite






16. Point of division between a telecommunications service carrier's network and a building's internal network






17. Connection based






18. UDP






19. Local area network






20. A digital communication service that uses the same network infrastructure as PSTN - but is expensive






21. LPD






22. RSA






23. Connectivity device - data link layer (2) - reads header info to forward packets according to MAC addresses






24. Constructs data frames using the appropriate format for the network - reatea CRC information - Checks for errors using CRC information - Retransmits data if there is error - Initiates the communications link and makes sure it is not interrupted - thu






25. Device used to regenerate a signal






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. Functions at the network layer that add logical addresses and properly route data






28. IIS






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






30. Data Link Layer






31. MIB






32. A form of address translation that uses Tcp port numbers to distinguish each client's transmission - thus allowing multiple clients to share a limited number of Internet-recognized IP addresses.






33. A Data Link sublayer of the OSI model that initiates the communication link between nodes and ensures the link is not unintentionally broken.






34. SMTP - simple mail transfer protocol

36. Basic error correction and detection






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






38. A data transmission rate






39. Time Division Multiple Access
