IT: Networking Vocab

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. Layer 1






2. The cabling or radio waves used to connect one network computer to another - or one network to another - and transport data between them. - Means by which a communications signal is carried from one system to another (for example - twisted-pair wire






3. 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






4. The combination of an IP address's network ID and subnet information. By interpreting the address's extended network prefix - a device can determine the subnet to which an address belongs.






5. TFTP - trivial file transfer protocol






6. Presentation Layer






7. A type of address translation in which a limited pool of internet-valid IP addresses is shared by multiple private network hosts.






8. Braided metal shielding used to insulate some types of coaxial cable






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






10. More reliable then analog - noise doesn't affect as much - more efficient - fewer errors






11. Glass/plastic - light pulses high throughput - resistant to noise - most expensive cable






12. What is the currency of Denmark?






13. HTTP/web/internet - change this port to make it more difficult for someone to connect to your web server






14. HTTP - SMTP - POP3 - VoIP






15. Layer 2






16. Serial internet protocol






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






18. International Organization for Standardization






19. Application layer protocol used to access information stored in a directory






20. Fiber Distributed Data Interface






21. Unit of data that results from subdividing a larger protocol data unit






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






23. Domain Name System






24. Signals travel in one direction






25. IDPS that uses profiles to detect anomalous protocol behavior






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






27. An app. that provides centralized authentication and authorization services for a network.






28. Carrier sense multiple access w collision detection (network access method) ethernet






29. Data transmission that involves one transmitter and one receiver






30. Physical layer standard for serial communications






31. Open source program that allows you too remotely take over another workstation and walk through support process






32. Connects multiple LANs






33. In CIDR notation - the number of bits used for an extended network prefix. For example - the CIDR block for 199.34.89.0/22 is /22






34. Provides service that ensure accurate and timely delivery of network communications between two hosts






35. NIDPS system that examines network traffic in order to identify problems related to the flow of traffic. Most sensors are passive mode deployment only.






36. Network news transfer protocol






37. Each node passively listens for then accepts data






38. NIS






39. Service that supports email






40. Frame






41. Individual insulated wire pairs - less expensive then STP - less resistant to noise






42. The IEEE stanard for error and flow control in data frames.






43. Translates data to a format the receiving node understands - such as from EBCDIC to ASCII - Performs data encryption - Performs data compression






44. On a network using the MIcrosoft Internet Connections Sharing service - the computer whose Internet connection other computers share. The ICS host must contain two network interfaces: one that connects to the Internet and one that connects to the LAN






45. 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.






46. Degradation of a light signal on a fiber-optic network






47. Using part of a leased line






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






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






50. A worldwide network network of interconnected LANs - and MANs - that uses the TCP/IP protocol to enable people to share e-mail messages and computer files and to access a vast array of infromation.
