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.

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






29. A generic term referring to any set of protocols and standards collected into a comprehensive grouping that - when followed by the devices in a network - allows all the devices to communicate. Examples include TCP/IP and OSI.






30. Computers connected together within a limited geographical area






31. PRI






32. Multiple signals travel simultaneously - medium is separated into multiple channels






33. Communications that occur in discrete units where the start of a unit is signaled by a start bit at the front and the end of the unit is signaled by a stop bit at the back.

37. A TCP/IP utility that at its simplest returns either to IP address of a host if its host name is specified or its host name if its IP address is specified






38. An IP addressing and subnetting method in which network and host information is manipulated without adhering to the limitations imposed by traditional network class distinctions. CIDR is also known as classless routing or supernetting. Older routing






39. A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't - the one carrying a signal will induce a 'ghost' signal in the other cable
