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.

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






18. A network design consisting of a continuous path for data with no logical beginning or ending point - and thus no terminators.






19. In TCP - a term used to describe a TCP header and its encapsulated data (also called an L4PDU). Also in TCP - the process of accepting a large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In






20. RJ 45






21. A connecting device for a network that accepts messages and passes them on to other parts of the network. Generally more intelligent than a hub.

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






26. A switching method that enables multiple devices to communicate over the same commnications medium by creating time slots in which each device transmits.






27. Prevents broadcast storms by enabling switches to calculate paths that avoid potential loops and artificially block the links that would complete a loop






28. Device that modulates analog signals into digital signals for transmission over telephone lines - and demodulates digital signals into analog for the receiving end
