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. Coordinates and maintains communications between two nodes on the network






2. Allows an attached computer to act as a dumb terminal - with data processing taking place on the TCP/IP host computer






3. TFTP - trivial file transfer protocol






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






5. You may set up a web server on companys access server - allowing global connections - for employees to access






6. 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.






7. IEEE standard for Ethernet devices and data handling






8. Fiber optic - enables one fiber optic connection to carry multiple light signals simultaneously






9. Moving from one BSS to another without losing connectivity






10. A generic term for data being transmitted






11. A data-link protocol used for remote networking that can exchange IP addresses - carry data by multiple network layer protocols - and support different app. protocols.






12. Hackers sending emails to make it look like its legit and its actually dangerous to the workstation






13. Each node is connected to the two nearest nodes so that the entire network forms a circle - active - twisted pair of fiber optic - single malfunction in workstation can disable entire network - not flexible or scalbe






14. A TCP/IP troubleshooting utility that provides information about NetBIOs names and their addresses. If you know the NetBIOs name of a workstation - you can use nbtstat to determine its IP address






15. When pulses that represent bits follow one another along a single transmission






16. Gives each node unique address






17. Session initiation protocol-performed on VoIP - determines location of endpoints - and establishes sessions between endpoints






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






19. BDC






20. AFP






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






22. TFTP is a TCP/IP file transfer protocol that is designed for task such as the transfer of data to enable a diskless workstation to boot using files trasmitted from a server






23. Type of multiplexing that assigns a unique frequncy band to each communications subchannel






24. Connector with 9 pins - commonly used in a serial communication that conforms to the rs-232 standard






25. Backbone: A high-capacity communications medium that joins networks on the same floor in a building - on different floors - and across long distances.






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






27. Network File System






28. Unwanted signals from sources near network cabling - such as motors and power lines






29. (metropolitan area network) used with a handful of buildings and larger then a LAN - connects two or more Lans






30. Device similar to a burglar alarm in that it detects a violation and activates an alarm.






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






32. Slow wireless standard 11-18 throughput






33. Several ethernet nodes can be connected and can monitor traffic or access media simultaneously






34. File Transfere Protocol






35. A systematic survey of all of the target organization's Internet addresses that is conducted to identify network services offered by hosts in that range






36. MIB






37. Enables network managers to continuously monitor network activity






38. A technique for connecting to a network at a remote location using Internet as the medium.






39. LDAP






40. Physical Layer






41. Device with little - if any - of it's own processing or disk capacity; depends on a host to supply it with applications and data-processing services






42. The scheme for assigning a unique identifying number to every node on a network






43. Connector used with single mode and multimode fiber optic cable






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






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






46. Glass/plastic - light pulses high throughput - resistant to noise - most expensive cable






47. Equivalent to OSI Layer 3 Network






48. A technique in which IP address used on a private network are assigned a public IP address by a gateway when accessing a public network.






49. 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.






50. Authentication prtocol that does not issue a challenge or require 3rd party verification of the computer requestiing authentication
