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






2. 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






3. __________________cards report computer errors and conflicts at POST.






4. 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






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






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






7. 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






8. 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.






9. 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.






10. 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






11. 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.






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






13. 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?






14. 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






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






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






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






18. 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.






19. Standard computer case form factor for modern computers.






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






21. 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.






22. 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.






23. Temporary drop in AC power.






24. This is how the BIOS communicates errors during POST






25. 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.






26. Memory that does not lose its data when the power is turned off.






27. 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.






28. Used to repair and reinstall Windows






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






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






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






32. 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.






33. POST means __________________.






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






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






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






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






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






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






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






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






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






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






44. 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.






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






46. 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






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






48. 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.






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






50. 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.
