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. Application Layer






2. Physical Layer






3. PPTP






4. Aka main cross-connect - first point of interconnection between an organization's LAN or WAN and a service provider's facility

6. Type of switching for multiple data packets make up the same transmission and use identical paths to reach the destination






7. Device that processes signals; multiplexer or modem






8. A connector that is used for thin coax cable and that has a boyonet-like shell.

10. Cause by length - loss of signals as it travels farther away






11. Services that handle hardware diagnoses and failure alerts






12. Does not operate at the application layer






13. Describes a theoretical representation of what happens between two nodes communicating on a network






14. Name Of Layer 4






15. Eight bits of information; in a digital signaling system - one byte carries one piece of information

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






37. A private network that functions like a tunnel though a large network-such as the Internet or an enterprise network-that is restricted to designated member clients only.






38. Is a protocol designed for managing complex networks






39. Is a host-to-host protocol like TCP - however it does not include mechanisms for ensuring timely delivery






40. ISM






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






42. IDPS that compares sampled network activity to established baseline






43. Which layer in the OSI network model handles data format information for networked communications?
