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. 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.






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






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






4. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






5. POST means __________________.






6. 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






7. 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.






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






9. A single hard drive that works independently of other hard drives.






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






11. A computer's ability to respond to a fault or catastrophe - such as a hardware failure or power outage - so that data is not lost.






12. The top or bottom surface of one platter on a hard drive. Each platter has two of these.






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






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






15. 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






16. A___________________can be used to test a USB port.






17. Protocol suite to network Macintosh computers. It is comprised of a comprehensive set of protocols that span the seven layers of the OSI reference model.






18. __________________cards report computer errors and conflicts at POST.






19. 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.






20. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






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






22. An interface standard - part of the IDE/ATA standards - that allows tape drives - CD-ROM drives - and other drives to be treated like an IDE hard drive by the system.






23. 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.






24. Windows Vista technology that supports a hybrid drive.






25. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






26. 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






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






28. 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.






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






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






31. A fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus.






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






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






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






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






36. Temporary drop in AC power.






37. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






38. High-speed - 32-bit bus technology designed to support the acceleration of 3D computer graphics.






39. 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






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






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






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






43. 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.






44. The one bootable partition.






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






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






47. 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






48. Network with each computer






49. Another name for the primary volume.






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