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. Term that describes current anti-intrusion technologies






2. A device used to connect thicknet cable with a transceiver. A vampire bypasses the need to serve the cable - because the vampire tap has a metal tooth that pierces through the outside cable insulation (like a vampire) and connects with the copper wir






3. Application Layer






4. Basic error correction and detection






5. QoS






6. 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.






7. The NIC and network equipment are set up so that they have the capacity to send and receive simultaneously. which is possible because od buffering at the NIC.






8. Process of breaking large packets into smaller packets.






9. Computers - devices - and connectivity necessary to rebuild a network exist - and all have appropriated configured updated and connected to match your networks current state. most expensive disaster recovery contingency to maintain






10. The placement of data from a higher-layer protocol behind the header (and in some cases - between a header and trailer) of the next-lower-layer protocol. For example - an IP packet could be encapsulated in an Ethernet header and trailer before being






11. Hardware that constitutes the enterprise-wide cabling system






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






13. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






14. 128-191






15. (fix) if analog an amplifier or if digital with repeater






16. Sequences packets in correct order






17. Radio frequency interference






18. IEEE






19. What is an agreed set of rules that two parties agree on in order to communicate with each other commanly known as?






20. Voltage is varied and imprecise - more susceptible






21. SSH






22. A poplar alternative to FTP is NFS software offered by Sun Microsystems - which uses Sun's remotr procedure call specification via TCP port 111.






23. HTTPS - Secure implementation of HTTP






24. Type of interference that may be caused by motors - power lines - televisions - copiers - etc






25. Decoy systems designed to lure potential attackers away from critical systems






26. Also called the star-ring hybrid - topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






27. A network transport control method used in Ethernet networks. It regulates transmission by sensing the presence of packet collisions.






28. User watching an episode of TV show over the internet is what kind of communication






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






30. Physical Layer






31. Positive and zero. 1 and 0's.






32. A type of fiber optic connector. These connectors are square shaped and have release mechanisms to prevent the cable from accidentally being unplugged






33. Data jack






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






35. Network-max segment length-100 meters






36. Layer 2






37. FM






38. A protocol data unit that has been transfered between OSI layers and then stripped of control information and transfere instructions.






39. Cross talk that occurs between wire pairs near the source of a signal






40. A network that offers services to members of the public - such as network services offered by a telecommunications company or a cable TV company.






41. Delay between the transmission of a signal and its receipt






42. IEEE standard for error and flow control in data frames






43. Provides FTP - HTTP - SMTP...






44. 2nd layer; bridges the networking media with the Network layer. Primary function is to divide the data it receives from the Network layer into frames to be transmitted by the Physical layer






45. Protocol data unit






46. NFS






47. AD






48. 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.






49. Layer 3 Troubleshooting






50. Media Access Unit (transmitter/ receiver)
