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. Which protocol is responsible for splitting data into packets and adding a header to each one?






2. Four twisted wire pairs rated for 250 MHz.






3. Communications cable that consists of one or more glass 0r plastic fiber cores inside a protective cladding material - covered by a plastic PVC outer jacket. Signal transmission along the inside fibers typically uses infrared light.






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






5. What is a unique name that identifies an internet site called?






6. A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility - but provides more information - even in its simplest form - than nslookup can.






7. QoS






8. Can use WPA to improve the security of data in transit






9. Event that triggers alarm when no actual attack is in progress






10. Type of transmission in which signals may travel in both directions over a medium simultaneously; also called duplex






11. The wave splits into secondary waves






12. FM






13. A versatile - chainable serial-bus technology that connects up to 127 devices at speeds of 1.5 Mbps and 12 Mbps as well as 480 Mbps.






14. A process in which a digital signature is placed in a driver. The digital signature helps ensure that the driver is tested and is compatible with the operating system and device for which it is written.






15. Collection of honey pots connecting several honey pot systems on a subnet






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






17. Supplying electrical power through ethernet






18. A network on which any computer can communicate with other networked computers on an equal (peer) basic without going though an intermediary - such as a server. Peer-to-Peer networking enables each computer to offer and access shared resoures - such






19. A single computer that provides extensive multiuser access to network resources - such as shared files - shared disks - and shared printers.






20. Wireless standard






21. A cable TV company - such as Comcast Broadband.






22. Techniques that employ hardware and software to province assurance against equipment failures - computer service interruptions - and data losses






23. In TCP - a term used to describe a TCP header and its encapsulated data (also called an L4PDU). Also in TCP - the process of accepting a large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In






24. Pointing in a direction






25. Analog - only one direction. radio frequency analog waves w differences in frequency. expensive - longer distance. ex. cable TV






26. Largest data unit a network will accept for transmission






27. An app. that provides centralized authentication and authorization services for a network.






28. Open System Interconnection






29. Controls the transport of data between systems






30. Application Layer






31. Requires CSU/DSU-the connection point for a t1 live at customers site






32. Network Layer






33. Modulates digital into analog in transmitting end and demodulates analog into digital in recieving end






34. Each node passively listens for then accepts data






35. Prevents broadcast storms by enabling switches to calculate paths that avoid potential loops and artificially block the links that would complete a loop






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

41. Device used to regenerate a signal






42. FTP - file transfer- control






43. Network Access Layer






44. A wireless station listens on all channels for a bacon frame from an access point






45. Braided metal shielding used to insulate some types of coaxial cable






46. FTP is an application that enables the transfer of data from one remote device to another - using TCP/IP






47. Device typically used to create a VLAN






48. Consists of single cable that connects all nodes on a network without intervening connectivity devices - inexpensive - hard to find source of error - not very fault tolerant - data is transmitted in one direction in the ring.






49. Transport layer protocol that requires the establishment of a connection between communicating nodes before it will transmit data
