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 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






2. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






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






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






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






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






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






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






11. 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.






12. 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.






13. 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






14. 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.






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






16. 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






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






18. 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.






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






20. 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.






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






22. 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.






23. __________________cards report computer errors and conflicts at POST.






24. Cable that contains four pairs of wires - with a maximum data rate of 1 Gbps.






25. 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.






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






27. 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.






28. Windows Vista technology that supports a hybrid drive.






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






30. 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?






31. A___________________can be used to test a USB port.






32. 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






33. 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






34. 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.






35. 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.






36. 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.






37. 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.






38. 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.






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






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






41. Another name for the primary volume.






42. 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






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






44. 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.






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






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






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






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






49. Used to repair and reinstall Windows






50. 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.
