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. Physical layer. 10 mpbs throughput. baseband transmission. max length is 100 meters. follows 5-4-3 rule. star topology. cat 3 or higher utp. twisted pair.






2. Used on many UNIX/LINUX systems to provide authentication security for TCP/IP applications such as Telnet and FTP






3. The _____________ allows certain bits of the IP address to be ignored when checking to see if an IP address matches the destination network address.






4. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






5. UDP






6. Multiple physical/non-physical mediums for connecting computers






7. Name Of Layer 6






8. A device that must be located at each end of a leased line.






9. BERT






10. Running system for a while to track types of false positives it generates and then adjusting IDPS alarm classifications






11. Signal that uses variable voltage to create continuous waves - resulting in an inexact transmission






12. Connectivity device - data link layer (2) - reads header info to forward packets according to MAC addresses






13. Not individually insulated but shielded. use when there is noise.






14. The most widely-used protocol that manages notes posted on usenet newsgroups






15. 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






16. Technique for formatting signals in which one property of a carrier wave is modified by the addition of a data signal during transmission






17. Default subnet mask for 154.13.44.87






18. Representatives from electronics manufacturers across the US that sets standards for electronic equipment and lobbies for legislation favorable to the growth of the computer and electronics industries






19. MAU






20. NFS






21. Speed: 10 Mbps - Alternative Name: 10BASE-T - IEEE Standard: IEEE 802.3 - Cable Type: Copper - max length 100 meters






22. First set of six characters that make up the MAC address and that are unique to a particular manufacturer






23. 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.






24. 4th layer; protocols ensure that data are transferred from point A to point B reliably and without errors; services include flow control - acknowledgment - error correction - segmentation - reassembly - and sequencing






25. Device that receives and retransmits microwave data signals






26. A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't - the one carrying a signal will induce a 'ghost' signal in the other cable






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






28. Developed by ISO and ANSI - a model that providees a framework for networked hardware and software communication based on seven layers.






29. 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.






30. Tools in order to connect a new RJ45






31. Provides Internet access and/or other services such as email and Web hosting






32. Measure of strength






33. QoS technique enables packet switches technologies to travel over traditionally circuit switched connections






34. An international body that establishes communications and networking standards - and that is particularly known for its contributions to network protocol standards.






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






36. A type of cable used in network wiring and is usually shielded - which means that it is more immune to interference then unshielded cables






37. Assigning a placeholder to each piece of a block of data to allow the receiving node's Transport layer to reassemble the data in the correct order






38. Transport protocol and TCP/IP port that uses telnet utility use






39. A type of multimode fiber-optic cable that reflects the light-based signals like a mirror within the cable - resulting in different signals arriving at different times and with an increased likeihood of distortion over longer cable runs.






40. Supplying electrical power through ethernet






41. 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






42. The first set of six characters that make up the MAC address and that are unique to a particular manufacturer.






43. Rules determining the format and transmission of data






44. This layer in the OSI transforms bits into electromagnetic signals.






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






46. Error detection and correction






47. UN agency that regulates international telecommunications and provides developing countries with technical expertise and equipment to advance their technological bases






48. A transmission method that has distinct signal levels to represent binary zeroes or ones - such as +5 volts and 0 volts.






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






50. Used to log on to a UNIX host
