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.
1. How do you change a computer's Boot Sequence?






2. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






3. Troubleshooting tool that allows the computer to boot from a disk when the hard drive will not boot.






4. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






5. A unit of measure that describes the size of a data file - the amount of space on a disk or other storage medium - or the amount of data being sent over a network. One byte consists of 8 bits of data.






6. A___________________can be used to test a USB port.






7. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






8. A transfer mode used by devices - including the hard drive - to transfer data to memory without involving the CPU.






9. This is how the BIOS communicates errors during POST






10. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.






11. An ATAPI cabling method that uses a narrower and more reliable cable than the 80-conductor cable.






12. A transfer mode that uses the CPU to transfer data from the hard drive to memory. This mode is slower than DMA mode.






13. A method of data transfer between hard drive and memory that allows multiple data transfers on a single software interrupt.






14. This tool can be used to test a USB port.






15. Standard that specifies full SATA cabling for external disks.






16. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi






17. List managed by a network administrator that itemizes what a user is permitted to access and the type of access granted.






18. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






19. Windows Vista technology that supports a hybrid drive.






20. Command used to check the integrity of files and folders on a hard drive by scanning the disk surface for physical errors.






21. You should write down or backup changes to CMOS/BIOS setup ____________________.






22. Is a type of drive imaging. It duplicates data on one drive to another drive and is used for fault tolerance.






23. One or more sectors that constitute the smallest unit of space on a disk for storing data (also referred to as a file allocation unit). Files are written to a disk as groups of whole clusters.






24. The advantages of ______________: To reduce the likelihood that the events that causes PC failures will occur and to lessen the damage if they do.






25. The one bootable partition.






26. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






27. Another name for the primary volume.






28. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






29. An IDE cable that has 40 pins but uses 80 wires - 40 of which are ground wires designed to reduce crosstalk on the cable.






30. The volume is assigned a drive letter (such as drive C: or drive D:) and is formatted using a file system. Also called simple volume.






31. The process - you specify the size of the partition and what file system it will use.






32. Used to repair and reinstall Windows






33. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






34. The first sector of a floppy disk or logical drive in a partition; it contains information about the disk or logical drive. On a hard drive - if the THING is in the active partition - then it is used to boot the OS. Also called boot sector.






35. A nonprofit organization dedicated to creating trade and communications standards.






36. The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. This device controls communication between the SCSI bus and the PC.






37. When troubleshooting a failed boot - if you do not see any lights or hear any noises - what hardware system do you first assume is at fault?






38. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






39. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






40. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






41. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






42. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






43. A sealed - magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.






44. Data storage area that provides high-speed access for the system.






45. A drive that uses both solid state and magnetic technologies.






46. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






47. The overall structure an OS uses to name - store - and organize files on a drive. In it - a cluster is the smallest unit of space on a disk for storing a file and is made up of one or more sectors. A it tracks how these clusters are used for each fil
