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.

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






19. Layer 4






20. TCP is a Layer 4 protocol (Due to the close match or the OSI Transport Layer and TCP within the TCP/IP Transport Layer.






21. A drawback of certification






22. Which protocol is responsible for splitting data into packets and adding a header to each one?






23. Layer 3 Troubleshooting






24. Presentation Layer






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






26. A app. loaded on a server included with Windows OS that enables remote access

31. Hardware address of the network interface card






32. ATM






33. Form of transmission that allows multiple signals to travel simultaneously over one medium






34. Firewall packet inspection that ignores the state of the connection between the internal computer and the external computer - only blocks or allows a packet based on header information.






35. Radio frequency interference. interference caused by radio.






36. 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.

46. Provides services for applications






47. An advantage of networks






48. Services that handle hardware diagnoses and failure alerts






49. Constructs data frames using the appropriate format for the network - reatea CRC information - Checks for errors using CRC information - Retransmits data if there is error - Initiates the communications link and makes sure it is not interrupted - thu






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