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 physical cables that link computers in a network






2. 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






3. Ethernet communications at speeds up to 100 Mbps as defined under the IEEE 802.3u standard.






4. Also called the star-ring hybrid - topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






5. Wavelength division multiplexing






6. Twist wire so you don't get interference on the memory






7. Carrier Sense Multiple Access with Collision Detection






8. Cross talk with 2+ wires






9. Device that enables networks or segments using different media to interconnect and exchange signals






10. Pointing in a direction






11. ISM






12. Wide area network






13. Manages end-to-end delivery of data






14. FTP-Data - file transfer data






15. Cause by EMI/RFI - and other packets - interference on the signal






16. Name Of Layer 3






17. A standard for encoding and interpreting binary files - images - video - and non-ASCII character sets within an e-mail message.






18. Two twisted wire pairs. It's the oldes type and is only voice grade - it isn't rated for data communication.






19. A connecting device for a network that accepts messages and broadcasts them out to the rest of the network.






20. Change in signal strength as a result of reflection - scattering - or diffraction






21. Style of data transmission in which the pulses that represent bits follow one another along a single transmission line; sequentially issued






22. Strategy in which all control functions are applied at the physical location of each IDPS component






23. A value or means of identifying a service on a network node - such as socket or port 103 for standerdized e-mail services in the TCP protocol.






24. Device similar to a burglar alarm in that it detects a violation and activates an alarm.






25. A connecting device for a network that accepts messages and forwards them to the correct section of the network. Generally more intelligent than a hub and a switch.






26. A far-reaching system of networks that usually extends over approximately 48 kilometers (about 30 miles) and often reaches across states and continents.






27. 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.






28. A very high speed - long distance media that consists of a single strand of fiber glass that carries the signals. Can transmit data 50 times further than multimode fiber at a faster rate






29. A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility - but provides more information - even in its simplest form - than nslookup can.






30. Routing protocol has the poorest convergence time






31. Signal interference caused by magnetic force field generated by electrical devices such as motors.






32. Requires many pulses to transmit same info that an analog can transmit in a wave






33. BERT






34. Media access control






35. 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.






36. 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






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






38. The _____________ allows certain bits of the IP address to be ignored when checking to see if an IP address matches the destination network address.






39. 5th layer; establishes and maintains communication between two nodes on the network; 'traffic cop'






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






41. Amount of data that can be transmitted over media or wireless at a time.






42. (WIde area network) Carry networks longer distances than Lans






43. A remote connection where the client computer is a low-end computer that communicates with a terminal server.






44. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






45. Frequency Division Multiple Access






46. A service on a node






47. An advantage of networks






48. Event that triggers alarms and causes an IDPS to react as if a real attack is in progress






49. Address resolution protocol






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