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. IP






2. A route discovery and analysis utility that comes with UNIX and Linux operating systems. Mtr combines with functions of the ping and traceroute commands and delivers an easily readable chart as its output






3. Also called the star-bus hybrid topology - a network design that combines the logial comunications of a bus with the physical layout of a star.






4. A form of fiber-optic cable that supports only one signal transmission at a time and that is used mainly for long- distance communication.






5. 192-223






6. A form of address translation that uses Tcp port numbers to distinguish each client's transmission - thus allowing multiple clients to share a limited number of Internet-recognized IP addresses.






7. Signals composed ot pulses that can have a value of only 1 or 0






8. The placement of data from a higher-layer protocol behind the header (and in some cases - between a header and trailer) of the next-lower-layer protocol. For example - an IP packet could be encapsulated in an Ethernet header and trailer before being






9. Digital subscriber line- support multiple data and voice channels over a single line - extraordinary throughput though telephone lines






10. Similar to FTP. lets you transfer files between a host and an FTP server






11. The shorter the wavelength






12. A type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.






13. The <html> - <head> and <body> tags are all examples of ________ tags






14. The seventh layer of the OSI model. Application layer protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network.






15. The transmission capacity of a communications medium - which is typically measured in bits per second (for data transmissions) or hertz (for data - voice - and video transmissions) - and which is determined by the maximum minus the minimum transmissi






16. A device used to connect thicknet cable with a transceiver. A vampire bypasses the need to serve the cable - because the vampire tap has a metal tooth that pierces through the outside cable insulation (like a vampire) and connects with the copper wir






17. A systematic survey of all of the target organization's Internet addresses that is conducted to identify network services offered by hosts in that range






18. Decreasing the size of data units when moving data from a network that can handle larger units to one that can handle only smaller units






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






20. Data Link Layer






21. Layer 1 Troubleshooting






22. Technology that uses standard telephone wires and allows transmission of voice and data information. Slower than ADSL.






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






24. Data changed since the previous fill or incremental backup






25. Theoretical. difference b/w highest and lowest frequency.






26. SSID






27. More variable - convey greater subtleties with less energy






28. Wall-mounted panel of data receptors into which cross-connect patch cables from the punch-down block are inserted






29. The sender transmits the data to the destination without establishment of a connection.






30. Layer 2 Troubleshooting






31. Telephone jacks






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






33. The scheme for assigning a unique identifying number to every node on a network






34. FTP-Data - file transfer data






35. 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






36. The capacity to send and receive signals at the same time on the same medium.






37. Tools in order to connect a new RJ45






38. Data Link Layer






39. Provides a generic method of transferring files






40. Equivalent to OSI Layer 4 Transport






41. Response generated atTransport layer confirming to sender that its frame was received; 3rd step in establishing a connection






42. Also called coax - a network cable medium that consists of a copper core - surrounded by insulation.






43. Cabling that transmit data using light waves. Higher bandwidth than other types of cabling.






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






45. Fiber-optic cable used on a network backbone for high-speed communications - such as between floors of a building.






46. Techniques that employ hardware and software to provide assurance against equipment failures - computer service interruptions - and data loss.






47. Round time trip. time it takes for packet to get from sender to receiver and back






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






49. Layer 2






50. Application layer protocol that formulates and interprets requests between Web clients and servers
