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. A number from 0 to 15 assigned to each SCSI device attached to the daisy chain.






2. Windows Vista technology that supports a hybrid drive.






3. This is how the BIOS communicates errors during POST






4. Expansion card that increases the number of controllers and ports available on a computer.






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






6. Backs up user-selected files to tape. This backup does not reset the archive bit.






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






8. To power up a computer from the off position.






9. The 12-bit wide - one-column file allocation table for a floppy disk - containing information about how each cluster or file allocation unit on the disk is currently used.






10. 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






11. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






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






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






14. Stripes data across three or more drives and uses parity checking - so that if one drive fails - the other drives can re-create the data stored on the failed drive. Data is not duplicated - and - therefore - THIS makes better use of volume capacity.






15. A drive with one - two - or more platters - or disks that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bot






16. Uses space from two or more physical disks to increase the disk space available for a single volume. THIS writes to the physical disks evenly across all disks so that no one disk receives all the activity - and therefore improves performance. Windows






17. 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.






18. Commonly called the host adapter. The host adapter is inserted into an expansion slot on the motherboard and is responsible for managing all devices on the SCSI bus. A host adapter can support both internal and external SCSI devices - using one conne






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






20. __________________cards report computer errors and conflicts at POST.






21. A set of tools - routines and protocols used to develop software applications that will be compatible with an operating system.






22. Four Main Parts of the boot process: 1. BIOS checks hardware through POST. 2. The ___________ searches for and loads an OS. 3. The OS configures the system and completes its own loading. 4. The user executes application software.






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






24. A Data Link layer device that connects and passes frames between two network segments. The frames are filtered and forwarded using MAC addresses.






25. A table on a hard drive or floppy disk that tracks how space on a disk is used to store files.






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






27. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






28. Layer 7 of the OSI reference model. This layer provides services to application processes such as electronic mail - file transfer - and terminal emulation that are outside of the OSI model. The application layer identifies and establishes the availab






29. The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain.






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






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






33. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






34. 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






35. 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.






36. 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.






37. 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






38. This can be divided into one or more logical drives. Each logical drive is assigned a drive letter (such as drive G:) and is formatted using its own file system.






39. 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:






40. POST means __________________.






41. Formatting performed by means of the DOS or Windows Format program (for example - FORMAT C:/S creates the boot record - FAT - and root directory on drive C and makes the drive bootable). Also called OS formatting.






42. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






43. 20-pin or 24-pin internal power supply connector.






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






45. Speed at which bits are transmitted - usually expressed in bits per second (bps).






46. When two hard drives are configured as a single volume.






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






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






49. The ________________makes sure the computer meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process.






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