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. NTP






2. NDS






3. Wireless standard






4. Layer 4






5. Narrow core - light travels in one path - longest distance - more expensive then MMF






6. BDC






7. Secure sockets layer-encyrpts TCP/IP transmission including web forms- en route b/w the client server using public key encryption technology






8. Consists of procedures and systems that identify system intrusions






9. Transport Layer






10. An error detection method that calculates a value for the total size of the information fields contained in a frame. The value is inserted near the end of a frame by the Data Link layer on the sending node - and checked by the Data Link layer on the






11. More reliable then analog - noise doesn't affect as much - more efficient - fewer errors






12. Constructs data frames using the appropriate format for the network - reatea CRC information - Checks for errors using CRC information - Retransmits data if there is error - Initiates the communications link and makes sure it is not interrupted - thu






13. A form of fiber-optic cable that supports only one signal transmission at a time and that is used mainly for long- distance communication.






14. AFP






15. An IP addressing and subnetting method in which network and host information is manipulated without adhering to the limitations imposed by traditional network class distinctions. CIDR is also known as classless routing or supernetting. Older routing






16. Twist wire so you don't get interference on the memory






17. 128-191






18. Controls the transport of data between systems






19. 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






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






21. ISM






22. Hubs and switches work here






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






24. IRC






25. Physical layout of a star topology and also ring logical topology






26. Physical layer. 100 mpbs throughout. baseband transmission. cat 5 or higher utp. max length is 100 meters. two wire twisted pair-full duplexing.






27. Is a host-to-host protocol like TCP - however it does not include mechanisms for ensuring timely delivery






28. A transport system that uses the CSMA/CD access method for data transmission on a network. Typically it is implemented in a bus or star-bus hybrid topology.






29. A gateway that operates on the Internet backbone.






30. Hard-to-define skills such as dependability






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






32. A unit of data formatted for transmission over a network that contains control and other information that corresponds to the OSI Networklayer; also called Layer 3.






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






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






35. Internet corporation for assigned names and numbers






36. A service on a node






37. Feeding everybody in building






38. Port used during a domain name lookup






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






40. Internet group management protocol






41. 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.






42. Is a TCP/IP service that converts a computer or domain name to an IP address or that converts an IP address to a computer or domain name.






43. Protocol that encapsulates data for transmission over VPNs






44. Method of error checking that determines if the contents of an arriving data unit match the contents of the data unit sent by the source






45. CNAME






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






47. 12-character string that uniquely identifies a network node - hard coded into the NIC by the manufacturer; composed ot the block ID and device ID






48. Used connecting a workstation to a routers console part






49. Device that separates multiplexed signals once they are received and regenerates them in their original form






50. BRI
