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






2. Data Link Layer






3. Techniques that employ hardware and software to provide assurance against equipment failures - computer service interruptions - and data loss.






4. Every node on the network is connected through a central device like a switch - cannot be disabled by a single malfunction in a workstation - scalable - - popular - expensive - cable malfunction will only effect 2 workstations - more fault tolerant.






5. Device that separates broadcast domain






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






7. HTTP/web/internet - change this port to make it more difficult for someone to connect to your web server






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






9. The physical cables that link computers in a network






10. A system of computers - printer devices - network devices - and computer software linked by communications cabling or radio waves.






11. 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.






12. Alert or alarm that occurs in the absence of an actual attack






13. The pattern used to install a network medium






14. A flexible communications cable that contains pairs of insulated copper wires that are twisted together for reduction of EMI and RFI and covered with an outer insulating jacket.






15. Layer 2






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






17. Which layer in the OSI is responsible for routing and controling the flow of packets around the network?






18. NDS






19. The device inside a computer that connect a computer to the network media






20. Regular voice-grade telephone service.






21. A cable that consists of a single cable sheath containing a combination of fibers and copper cable.






22. Open source program that allows you too remotely take over another workstation and walk through support process






23. Physical Layer






24. Associates a MAC address with a given IP address - reverse ARP






25. The general topic of how on one computer - two adjacent layers in a networking architectural model work together - with the lower layer proving services to the higher layer.






26. RJ 11






27. BERT






28. LLC






29. Unlicensed band with 11 channels






30. QoS






31. 6th layer; protocols translate between Application and Network layers; data are formatted so that the network can understand - with the format varying according to the type of network; manages data encryption and decryption - such as scrambling of sy






32. 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.






33. Internet Layer






34. Application Layer






35. IPv4






36. 1-126






37. 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






38. FDDI






39. Degradation of a light signal on a fiber-optic network






40. Tools in order to connect a new RJ45






41. A situation in which two or more packets are detected at the same time on an Ethernet network.






42. Public switched telephone network






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






44. Used with single mode or multi mode fiber optic cable






45. A private network that functions like a tunnel through a larger network






46. EMI interference induced on one cable by signals traveling on a nearby cable






47. Device that acts as a wireless switch so that nodes can connect wirelessly to a network.






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






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






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