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






2. 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.






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






4. Used to repair and reinstall Windows






5. A drive with no moving parts. Uses nonvolatile flash memory.






6. 20-pin or 24-pin internal power supply connector.






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. To power up a computer from the off position.






9. 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.






10. 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.






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






12. 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.






13. 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.






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






15. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






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






17. 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.






18. 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.






19. A________________CD can be used to boot a system and repair or reinstall Windows.






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






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






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






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






24. The duplication of everything written to a hard drive.






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






26. 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.






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






28. 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?






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






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






31. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






32. 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.






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






34. 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.






35. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






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






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






38. Temporary drop in AC power.






39. Standard computer case form factor for modern computers.






40. 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.






41. 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






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






43. 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






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






45. 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.






46. 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






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. Standard that specifies full SATA cabling for external disks.






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






50. Windows Vista technology that supports a hybrid drive.
