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. AM






2. Small Form Plug-gables - Plugs in to an interface on a switch






3. MAU






4. Four twisted wire pairs rated for 250 MHz.






5. Long reach. multimode max length is 550 meters. single mode max length is 5000. 1000 mpbs. baseband transmission






6. 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






7. Groups of workstations are star connect to connectivity devices and then networked via single bus - cover long distances - easy to interconnect - more expensive - ethernet






8. The ability to send or receive signals on a medium - but not at the same time.






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






10. First set of six characters that make up the MAC address and that are unique to a particular manufacturer






11. A professional membership society that helps establish technical standards for the internet






12. Power loss - the amount of signal that is lost as it travels though the communication medium from the source (transmitting node) to the receiving node.






13. Data jack






14. Communications that occur in discrete units where the start of a unit is signaled by a start bit at the front and the end of the unit is signaled by a stop bit at the back.






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






17. Simple Mail Transfer Protocol






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






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






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






21. ACL






22. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






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






24. A network design consisting of a continuous path for data with no logical beginning or ending point - and thus no terminators.






25. Transport Layer






26. 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.






27. A worldwide network network of interconnected LANs - and MANs - that uses the TCP/IP protocol to enable people to share e-mail messages and computer files and to access a vast array of infromation.






28. A network transport control method used in Ethernet networks. It regulates transmission by sensing the presence of packet collisions.






29. A specialized device that allows multiple networks or segments to connect and exchange data






30. Maximum arc into which you can loop a cable before you will cause data transmission errors






31. Network Layer






32. Set of routines that make up part of a software application






33. Which protocol is responsible for splitting data into packets and adding a header to each one?






34. Institute of electrical and electronics engineers






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






36. F type (like TV cable) or BNC (crimped)






37. Ethernet cable - high resistance to noise - networks are RG 6






38. IEEE 802.3 Media Access Control (MAC) sublayer of the data link layer






39. Defines the physical characteristics of the network






40. Carrier sense multiple access w collision detection (network access method) ethernet






41. International Organization for Standardization






42. The IEEE standard for Ethernet networking devices and data handling (using the CSMA/CD access method)






43. Measure of strength






44. Application Layer






45. Cross talk that occurs between wire pairs near the source of a signal






46. Multiplexing technique use over single-mode or multimode fiber-optic cable in which each signal is assigned a different wavelength for its carrier wave; little space exists between carrier waves






47. Term that describes current anti-intrusion technologies






48. LPD






49. Data Link Layer






50. Network layer service that subdivides segments it receives from the Transport layer into smaller packets
