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






2. The communication between two networking devices for the purposes of the functions defined at a particular layer of a networking model - with the communication happening by using a header defined by that layer of the model. The two devices set values






3. Provides a generic method of transferring files






4. Provides FTP - HTTP - SMTP...






5. Data Link Layer






6. Network Layer

8. Device that connects network segments and directs data based on information in the data packet






9. Integrated digital network






10. A variation of CHAP designed by Microsoft






11. A very high speed - long distance media that consists of a single strand of fiber glass that carries the signals. Can transmit data 50 times further than multimode fiber at a faster rate






12. 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.






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






14. Enables the establishment of a Web connection - but it also provides for the exchange of resources - for example - displaying AOL's Web page in your brower.






15. Application Layer






16. Network layer service that subdivides segments it receives from the Transport layer into smaller packets






17. A network topology in which all of the nodes are connected to a central line or bus






18. Ethernet LAN-all forms of Ethernet media and interface






19. Used connecting a workstation to a routers console part






20. Specify clients configurations to adhere to this subnet






21. SONET






22. 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.






23. An adapter board designed to connect a workstation - server - or other network device to a network medium.






24. Networking technology developed by IBM in the 80s; relies upon direct links between nodes and ring topology - using tokens to allow nodes to transmit data






25. System founded on using 1s and 0s to encode information






26. Device that can detect intrusion and launch an active response






27. A logical communication path established by the OSI Network layer for sending and receiving data.






28. A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address - or vice versa. This is useful for verifying that a hos is configured correctly and for troubleshooting DNS resolution problems






29. A network owned and maintained by an organization -such as a campus network operated by a college.






30. Is used to allow searching and updating of a directory service






31. Gives each node unique address
