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






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






3. Windows Vista technology that supports a hybrid drive.






4. 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.






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






6. The one bootable partition.






7. 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.






8. 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.






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






10. __________________cards report computer errors and conflicts at POST.






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






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






13. 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.






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






15. 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






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






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






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






20. 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






21. 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.






22. 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.






23. POST means __________________.






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






25. 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.






26. 20-pin or 24-pin internal power supply connector.






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. 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.






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






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






31. Network with each computer






32. You should write down or backup changes to CMOS/BIOS setup ____________________.






33. 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.






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






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






36. 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






37. 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.






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






39. 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






40. 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






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






42. How do you change a computer's Boot Sequence?






43. 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.






44. This is how the BIOS communicates errors during POST






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






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






47. Standard computer case form factor for modern computers.






48. 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?






49. 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.






50. 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.
