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






2. Which protocol is responsible for routing packets around the network?






3. Communications cable that consists of one or more glass 0r plastic fiber cores inside a protective cladding material - covered by a plastic PVC outer jacket. Signal transmission along the inside fibers typically uses infrared light.






4. The process of wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer. For example - Data Link layer protocols encapsulate Network layer packets in frames.






5. Length of time it takes for a packet to go from sender to receiver - then back to sender; measured in milliseconds






6. Professional organization with 90 chapters around the world that helps to establish technical standards for the internet






7. IEEE standard for wireless networking






8. Pieces of hardware that connect the wire to the network device






9. Amplitude modulation-amplitude of signal is modified






10. Aka main cross-connect - first point of interconnection between an organization's LAN or WAN and a service provider's facility






11. A type of subnet that is created using bits that normally would be reserved for network class information by moving the subnet boundary to the left.






12. 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.






13. Type of protocol useful when data must be transferred quickly






14. A medium that carries 1 signal






15. Protocol used to transfer mail between a send mail server and microsoft exchange server






16. LC - ST - SC - or MT RJ






17. Software that is stored on a chip in a device - such as in a ROM - and that typically composes some type of system software






18. WAN transmission technologies that contains a segment that relied on 10GBase-EW standard






19. 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






20. This layer in the OSI network model manages log on procedures and password recognition.






21. Radio frequency interference. interference caused by radio.






22. Small network 192-223






23. Large diameter. led/light is generated at different angles. high throughput - high noise resistance - excellent security - and long distances






24. AH






25. A shell protocol that enables systems to use various authenticaion mechanisms.






26. Performs name resolution






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






28. The IEEE standard for broadband wireless metropolitan area networking (also known as WiMax)






29. AD






30. Open Systems Interconnection model is standard description or reference model for how messages should be transmitted between any 2 points in a telecommunications network.






31. Used to log on to a UNIX host






32. 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






33. A service provided with Windows 98 - Me - 2000 - and 32-bit versions of XP operating systems that allows one computer - the ICS host - to share its Internet connection with other computers on the same network.






34. Upper sublayer in the Data Link layer. Provides a common interface and supplies reliability and flow control services






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






36. Frequency hoping spread spectrum: a signal jumps between several different frequencies






37. HDLC






38. A connector used to terminate coaxial cable used for transmitting television and broadband cable signals






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






40. Layer 5 through 7 Troubleshooting






41. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






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






43. A series of interconnected computers - printing devices - and other computer equipment that shares hardware and software resources. The service area usually is limited to a given office area - floor - or building.






44. Reflection in multiple different directions of a signal






45. Unix command at shell prompt to send a file to printer






46. Enables the establishment of a Web connection - but it also provides for the exchange of resources - for example - displaying AOL's Web page in your brower.






47. The most commonly used form of Post office protocol.






48. Layer 2 Troubleshooting






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






50. IPX
