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.

10. A coaxial connector uses a twist and lock style - may be used with Rg-6 and RG-59






11. The process of checking a communication medium - such as cable - for a voltage level - signal transition - or light - indicating the presence of a data-carrying signal.






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






13. L2F

15. The actual data - any communication that encodes a message






16. Two twisted wire pairs. It's the oldes type and is only voice grade - it isn't rated for data communication.






17. Media access control






18. Digital - one signal one channel at a time (half duplexing) ex. ethernet






19. A type of cabling that includes pairs of copper conductors - twisted around each other - inside a metal or foil shield. This type of medium can support faster speeds than unshielded wiring






20. Layer 5 through 7 Troubleshooting






21. Is a method for automatically assigning address and other configuration parameters to network hosts.






22. A far-reaching system of networks that usually extends over approximately 48 kilometers (about 30 miles) and often reaches across states and continents.






23. Equivalent to OSI Layer 7 Application - Layer 6 Presentation - Layer 5 Session






24. A term used to refer to data within the Data-link layer of the OSI model.






25. Software that enables a computer to communicate with devices such as NICs - printers - monitors - and hard disk drives.






26. Where demarc is located if an organization follows structured cabling standards






27. An authentication protocol that uses public key technology to provide users with secured access to network resources.






28. Virture privat network






29. Saturation of network bandwidth caused by excessive traffic - as when a large number of computers or devices attemp to transmit simultaneously - or when computers or devices presist in transmitting repeatedly.






30. An 8-bit character-coding method consisting of 96 uppercase and lowercase characters and numbers - plus 32 nonprinting characters.






31. A type of point-to-point digital WAN connection that uses standard phone lines to provide high-speed comm.






32. Cyclic redundancy check






33. An enclosed area - such as a false floor - or ceiling - in which pressure from air or gas can be greater than the pressure outside the enclosed area - particularly during a fire. Plenum area in buildings often extend to multiple rooms or extend throu






34. The physical layout of a computer network






35. String used to identify an access point - configure on your new access points to match the settings on existing access points






36. A fixed number associated with a device's NIC

40. Ethernet cable - high resistance to noise - networks are RG 6






41. A TCP/IP troubleshooting utility that uses ICMP to trace the path from one networked node to another - identifying all intermediate hops between the two nodes. Traceroute is useful for determining router or subnet connectivity problems. On Windows-ba






42. 2nd set of characteristics that make up a device's MAC address. Added at the factory and is based on the device's model and manufacture date






43. 192-223
