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. 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






2. Saturation of network bandwidth caused by excessive traffic - as when a large number of computers or devices attemp to transmit simultaneously - or when computers or devices presist in transmitting repeatedly.






3. Assigning a placeholder to each piece of a block of data to allow the receiving node's Transport layer to reassemble the data in the correct order






4. 3rd layer; protocols translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver






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






6. Dynamic Host Configuration Protocol






7. NTP






8. CSMA / CD






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






10. 6th layer; protocols translate between Application and Network layers; data are formatted so that the network can understand - with the format varying according to the type of network; manages data encryption and decryption - such as scrambling of sy






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






12. Which protocol allows the transfer of a file from one computer to another over the network?






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






14. Wavelength division multiplexing






15. You may set up a web server on companys access server - allowing global connections - for employees to access






16. Strength of digital signal






17. A type of transmission in which the entire channel capacity of the communications medium (such as cable) is used by one data signal - enabling only one node to transmit at a time.






18. Developed by ISO and ANSI - a model that providees a framework for networked hardware and software communication based on seven layers.






19. The Application layer TCP/IP subprotocol responsible for moving messages from one e-mail server to another.






20. A cable TV company - such as Comcast Broadband.






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






22. The information transfered between layers in the same OSI stack






23. The physical cables that link computers in a network






24. Compatible with 802.11a - b - g 600-65 throughput






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






26. 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






27. The process in which an attacker obtains confidential information by contacting employees and deceiving them into giving up passwords - IP addresses - server names - and so on.






28. AM






29. IANA






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






31. Network time protocol






32. Twisted pair patch cable in which the termination locations of the transmit and receive wires on one end of the cable are reversed






33. User watching an episode of TV show over the internet is what kind of communication






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






35. Gigabit Interface Converter - Plugs in to an interface on a switch






36. Internet Engineering Task Force






37. Point or stage in a wave's progress over time






38. Secure sockets layer-encyrpts TCP/IP transmission including web forms- en route b/w the client server using public key encryption technology






39. Is usde to communicate time synchronization information between systemson a network






40. Data Link Layer






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






42. FDM






43. Transport layer protocol that services a request without requiring a verified session and without guaranteeing delivery data






44. PPPoE






45. Standard rating that indicates the diameter of a wire






46. Anything - hardware or software - that monitors transmission of packets of digital information that attempt to pass the perimeter of a network






47. Provides FTP - HTTP - SMTP...






48. Performs name resolution






49. Is a TCP/IP service that converts a computer or domain name to an IP address or that converts an IP address to a computer or domain name.






50. IEEE standard for error and flow control in data frames
