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. 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






2. 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.






3. 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.






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. 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






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






7. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






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






12. This is how the BIOS communicates errors during POST






13. 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.






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






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






16. 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?






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






18. 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?






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






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






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






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






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






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






25. 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.






26. Used to repair and reinstall Windows






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






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






29. 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.






30. 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.






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






32. Temporary drop in AC power.






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






34. 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.






35. 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






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






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






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






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






40. 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.






41. When two hard drives are configured as a single 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. 20-pin or 24-pin internal power supply connector.






44. 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






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






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






47. 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






48. Standard computer case form factor for modern computers.






49. __________________cards report computer errors and conflicts at POST.






50. 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.
