TIA Test 2 The Test Write your name at the beginning of the test Save the test as TIA Test 2 Your Name. If your name is Fred Smith then same the test as TIA Test 2 Fred Smith Write your answers to each statement at the end of each statement. Your answers are either true or false. You may write T for true and F for false After the test create an e-mail Without zipping the test, attach the test to the e-mail Write TIA Test 2 in the e-mail’s body Write your name in the e-mail’s subject field Attach your test to the e-mail Send the e-mail to [email protected] Do not leave the classroom until you make sure that I got your email TIA Test 2 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 38. 39. 40. 41. A device driver facilitates the communication between an OS and a device A MAN usually has more computers than a HAN A PAN usually has more computers than a WAN A router transfers data between 2 or more networks A switch and a router perform the same tasks Actual data throughput is usually higher on wired networks than on wireless networks All computers have operating systems An operating system facilitates the communication between a device and its device driver Android 3.0 runs on laptops, desk-tops and all-in-ones Bandwidth is always greater than data transfer Bandwidth is always greater than throughput Cache memory transfers data faster than RAM Data transfer rate is always greater than bandwidth Data transfer rate is the maximum speed at which data can be transmitted between two nodes of a network Each node on a network needs a network adapter Home networks are P2P networks In a client-server network each node is connected on the network can communicate directly with every other node on the network Lands are not a feature of optical disks Linux runs on cell phones and tablets Many routers allow you to restrict access to the network to only certain MAC addresses Mechanical hard drives have no mechanical motors or moving parts Mechanical hard drives transfer data faster than cache memory More than one operating system can run on a computer No computer has an operating system Only one operating system can run on a computer Over-clocking decreases CPU life tm. Over-clocking increases CPU life time Pits are a feature of optical disks Restricting the range of your wireless network’s signal makes it tougher for interlopers to poach your signal Solid state drives have no mechanical motors or moving parts Some computers have operating systems The audio subsystem has its own processor The BIOS is a component of the POST The BIOS runs after the POST The BIOS runs before the POST The operating system’s memory manager does not manage cache memory The operating system’s memory manager manages cache memory The POST is a component of the BIOS The servers on peer-to-peer networks have specialized network operating system software installed The solution to thrashing is to increase virtual memory The visual subsystem has its own processor TIA Test 2 42. 43. 44. 45. 46. 47. 48. Thrashing occurs when your computer has more virtual memory than actual memory Throughput is always greater than bandwidth Throughput is the actual speed of data transfer between two nodes of a network Turning off your SSID broadcasting makes it easier for hackers to detect your network Wired networks are more vulnerable to hackers than wireless networks Wireless networks transmit data faster than wired networks because fiber-optic cables transmit data at extremely high speeds With multiple-core technology, two or more complete processors live on the same chip.
