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.

19. Port used during a domain name lookup






20. 7th layer; protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network






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

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






24. QoS






25. The process of checking a communication medium - such as cable - for a voltage level - signal transition - or light - indicating the presence of a data-carrying signal.






26. 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.






27. Session Layer






28. A standard method or format for communication between networked devices
