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. An algorithm used to verify the accuracy of data contained in a data frame.






2. Point to point protocol






3. Institute of electrical and electronics engineers






4. A network design in which every node is connected to every other node - achieving fault tolerance.






5. Signal that uses variable voltage to create continuous waves - resulting in an inexact transmission






6. Allows you and eight coworkers to share a single internet routable IP address






7. Networking technology developed at Xerox in the 70s and improved by Digital Equipment Corp - Inel - and Xerox. Most common form of network transmission - follows IEEE 802.3 standard






8. Type of multiplexing that assigns a unique frequncy band to each communications subchannel






9. Hardware device located at the ISP side of ADSL connections.






10. IEEE






11. A combination of LAN's - MAN's - or WAN's that provides computer users with an array of computer and network resources to complete different tasks.






12. Process in which an NIDPS look for invalid data packets - packets that are malformed under the rules of the TCP/IP protocol






13. Frame






14. Translated network addresses into their physical counterparts






15. IEEE standard for wireless networking






16. Dynamic host configuration protocol






17. The physical layout of the cable and wireless network devices and the logical path followed by network frames and packets sent on the cable or by wireless transmissions






18. Secures messages being transmitted on the internet - uses RSA for authentication and encyption.






19. The NIC and network equipment are set up so they cannot send and receive at the same time






20. Type of transmission in which signlas may travel in both directions over a medium - but only in one direction at a time






21. CSMA / CD






22. Sequences packets in correct order






23. Logical link control






24. HDLC






25. 5 segments b/w two nodes - 4 repeating devices - and 3 segments connected by two repeating devices






26. The general topic of how on one computer - two adjacent layers in a networking architectural model work together - with the lower layer proving services to the higher layer.






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






28. 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






29. The first set of six characters that make up the MAC address and that are unique to a particular manufacturer.






30. Defines the physical characteristics of the network






31. IGMP






32. A network whose access is restricted to only clients or machines with proper credentials.






33. Ppp over ethernet






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






35. A transport system that uses the CSMA/CD access method for data transmission on a network. Typically it is implemented in a bus or star-bus hybrid topology.






36. Protocol data unit. An OSI term to refer generically to a grouping of information by a particular layer of the OSI model. More specifically - an LxPDU would imply the data and headers as defined by Layer x.






37. A computer on a network that requests services or resources from another computer on a network






38. The distinct units of data that are exchanged between nodes on a network






39. A process that ensures one device does not send information faster than it can be received by another device.






40. Shielded twisted pair






41. Firewalls perform two basic security functions






42. A device that can transmit and receive - such as transmitting and receiving signals on a communication cable






43. BootP






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






45. Vulnerability created in a system by a virus or worm which allows the attacker to access the system at will with special privileges.






46. A digital communication service that uses the same network infrastructure as PSTN - but is expensive






47. A computer that accesses another computer - such as a workstation that accesses a shared file on another workstation - server - or mainframe. The client may use the accessed computer (host) to process data - or may process accessed data using its own






48. A type of fiber optic connector. These connectors are square shaped and have release mechanisms to prevent the cable from accidentally being unplugged






49. A set of routines that make up part of a software application






50. Layer 1 Troubleshooting
