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. Four twisted wire pairs rated for 250 MHz.






2. What is the term used when every host on the network has a fixed IP address?






3. Determines the network path on which to route packets - Help reduce network congestion - Establishes virtual circuits - Routes packets to other networks - resequencing packet transmissions when needed - Translates between protocols






4. Is a system that is distributed throughout the internetwork to provide address/name resolution.






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






6. A generic term for data being transmitted






7. Manages IP address allocation and the domain name system






8. SMTP - simple mail transfer protocol






9. The shorter the wavelength






10. Measure of the difference between the highest and lowest frequencies that a medium can transmit






11. A logical grouping of information that includes the network layer header and encapsulated data - but specifically does not include any headers and trailers below the network layer.






12. Transport Layer






13. On a computer that receives data over a network - the process in which the device interprets the lower-layer headers and - when finished with each header - removes the header - revealing the next-higher-layer PDU.






14. SSID






15. Also called the star-wired ring topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






16. The physical layout of cable and wireless network devices and the logical path followed by network frames or packets sent on the cable or by wireless transmissions.






17. Defines host IP in packet headers






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






19. 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.






20. Moving from one BSS to another without losing connectivity






21. A protocol data unit that has been transfered between OSI layers and then stripped of control information and transfere instructions.






22. L2TP






23. 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






24. 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.






25. A combination of LAN's - MAN's - or WAN's that provides computer users with an array of computer and network resources to complete different tasks.






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






27. Protocol data unit






28. Layer 3 Troubleshooting






29. The wave bounces back when encountering an object






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






31. The organized research of the Internet addresses owned or controlled by a target organization.






32. Process of directing a datagram from its source through an internetwork to its destination using the most efficient path.






33. Honey pot that has been protected so it cannot be easily compromised






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






35. A network that links multiple LANs in a large city or metropolitan region.






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






37. Supplying electrical power through ethernet






38. An International organization of scientists - engineers - technicians - and educators that play a leading role in developing standards for network cabling and data transmissions.






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






40. Divides channel into different time slots and assigns data to nodes who are attached to time slots






41. Type of interference caused by signals traveling on nearby wire pairs infringing on another pair's signal






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






43. A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility - but provides more information - even in its simplest form - than nslookup can.






44. A type of transmission in which there are several transmission channels on a communications medium - allowing more than one node to transmit at the same time.






45. Most common cabling used in networking. Usually connects nodes to the main network.






46. IPX & SPX






47. Physical layer. 10 giga bit throughput. baseband transmission. twisted pair. max length is 100 meters. cat 6 or 7.






48. Guarantees that a server continually has power even if a buildings electrical service is interrupted - continuous voltage to a device by switching virtually instantaneously to the battery when it detects loss of power






49. Max number of hops a packet can take b/w its source and destination using RIP on a LAN






50. Describes the relative strength over a three dimensional area of an antenna
