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. 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.






2. 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.






3. 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?






4. 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.






5. 20-pin or 24-pin internal power supply connector.






6. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






7. 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.






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






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






10. 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.






11. A hard drive whose disk controller is integrated into the drive - eliminating the need for a controller cable and thus increasing speed - as well as reducing price.






12. __________________cards report computer errors and conflicts at POST.






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






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






15. Standard computer case form factor for modern computers.






16. Involves restarting the computer by pressing the on/off switch. Stressful on computers.






17. 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.






18. Fastener used to bundle cables inside and outside of a computer.






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






20. This is how the BIOS communicates errors during POST






21. 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.






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






23. 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.






24. 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






25. 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






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






27. 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






28. POST means __________________.






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






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






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






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






33. 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






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 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






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






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






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






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






40. 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.






41. Windows Vista technology that supports a hybrid drive.






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






43. 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.






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






45. 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.






46. 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.






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






48. The one bootable partition.






49. Five possible questions that should be asked of a user who is experiencing computer problems: What had just happened? What recent changes did the user make? When did the computer __________? What error message do you see?






50. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.
