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. Media Access Unit (transmitter/ receiver)






2. Example of an internetwork






3. Enables sharing remote drivers - Enables sharing remote printers - Handles e-mail messages - Provides file transfer services - Provides file management services - Provides terminal emulation






4. Measure of frequency equivalent to the number of amplitude cycles per second






5. (fix) if analog shield twisted pairs or if digital with a repeater






6. Secure CoPy-utility that allows you to copy files securely from host to another






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






8. String used to identify an access point - configure on your new access points to match the settings on existing access points






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






10. Transmission that involves one transmitter and multiple - undefined receivers






11. The oldest type of network design - this topology consists of multiple nodes attached to a central hub - switch - or router.






12. Transport Layer






13. A cable that consists of a single cable sheath containing a combination of fibers and copper cable.






14. Is a file transfer protocol that uses s ecure shell (SSH)






15. A termination unit also called a transceiver or DSL modem






16. IEEE standard for wireless networking






17. Short reach. only multimode-max length is 500. baseband transmission. 1000 mpbs.






18. Is used to route electronic mail through the internetwork






19. Layer 1 Troubleshooting






20. Resistance that contributes to controlling an electrical signal; measured in ohms






21. Uses frame headers






22. Crimp into pins 1 and 2 of RJ 45 connector






23. An adapter board designed to connect a workstation - server - or other network device to a network medium.






24. Data jack






25. Actual. how much data is transmitted during given time






26. Wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer






27. Nondata info that must accompany data for it to be properly routed. addition to data






28. Eight bits of information; in a digital signaling system - one byte carries one piece of information






29. 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






30. A digital communication service that uses the same network infrastructure as PSTN - but is expensive






31. A mail retrieval protocol that improves on the shortcomings of POP. The single biggest advantage IMAP4 has relative to POP is that it allows users to store messages on the mail server - rather than always having to download them to a local machine.






32. A system of computers - printer devices - network devices - and computer software linked by communications cabling or radio waves.






33. A TCP/Ip troubleshooting utility that displays statistics and the state of current TCP/IP connections. It also displays ports - which can signal whether services are using the correct ports.






34. Control frame that indicates to the rest of the network that a particular node has the right to transmit data






35. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






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






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






38. IPX






39. Metropolitan area network






40. A variation of CHAP designed by Microsoft






41. 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.






42. The physical layout of a computer network






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






44. For fiber-optic cable communications - the difference between the transmitted power and the receiver sensitivity - as measured in decibels. It is the minimum transmitter power and receiver sensitivity needed for a signal to be sent and received fully






45. On a cable-TV WAN - a central receiving point for signals from various sources - including satellite - major cable sources - and local tevevision sources.






46. Packet one node sends to request a connection with another; 1st of three-step process of establishing a connection






47. Data terminal equipment - little independent data processing capability. ex. workstation






48. A connector that is used for thin coax cable and that has a boyonet-like shell.






49. Equivalent to OSI Layer 3 Network






50. NNTP
