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 unit of data transmitted on a network that contains control and address information corresponding to the OSI Data Link layer - or Layer 2.






2. Which address is split in to four 8-bit parts called octets?






3. Any device connected to a network - such as a microcomputer - mainframe - midrange computer - network equipment - or printer. Also called a station.






4. End-user device - such as a workstation - terminal - or console






5. Term that describes current anti-intrusion technologies






6. Provides services for applications






7. The more resistant to cross talk (STP)






8. A network topology in which all of the nodes are connected to a central line or bus






9. (WIde area network) Carry networks longer distances than Lans






10. A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address - or vice versa. This is useful for verifying that a hos is configured correctly and for troubleshooting DNS resolution problems






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






12. Transforms data into a form network or applications will understand






13. Any end device on the network (for example: computers - printers - copy machines...)






14. These reside on a computer or appliance connected to network segment and monitor network traffic






15. Attacker who utilizes tactics designed to trip the organization's IDPS - essentially causing the organization to conduct its own DoS attack - but overreacting to an actual - but insignificant - attack.






16. 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






17. Network device that makes high-level application connections on behalf of internal hosts and other machines






18. The information transfered between layers in the same OSI stack






19. UDP






20. Frequency modulation-frequency of signal is modified






21. Package for data that includes not only the data - or 'payload -' but also the sender's and recipient's addressing and control information. Generated at the Data Link layer and issued to the Physical layer






22. Panel of data receptors into which twisted pair wire is inserted to complete a circuit






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






24. Addresses packet size






25. One transmitter issues signals to multiple receivers; receivers may be undefined or defined






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






27. Which layer is responsible for putting data into frames as well as providing error checking data?






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






29. Best fault tolerance






30. 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






31. IMAP - internet message access protocol






32. Is used to route electronic mail through the internetwork






33. Encompasses actions an organization takes when intrusion is detected






34. Network news transfer protocol






35. Transport Layer






36. In CIDR notation - the number of bits used for an extended network prefix. For example - the CIDR block for 199.34.89.0/22 is /22






37. Establishes maintains and terminates connections






38. A TCP/IP troubleshooting utility that uses ICMP to trace the path from one networked node to another - identifying all intermediate hops between the two nodes. Traceroute is useful for determining router or subnet connectivity problems. On Windows-ba






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






40. Uses light to communicate a signal; the light is dispersed on numerous paths as it travels through the core and is reflected back. Provides high bandwidth at high speeds over medium distances up to about 3000 feet






41. 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






42. The process of reconstructing segmented data






43. An arm of the Internet Society (ISOC) that works on Internet-relateed technical issues.






44. A set of routines that make up part of a software application






45. Trivial File Transfer Protocol






46. Distance between corresponding points on cycle






47. Physical Layer






48. Institute of electrical and electronics engineers






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






50. A network that any user can access with no restrictions. the most familiar example of a public network is the Internet
