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. POST means __________________.






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






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






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






5. 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.






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






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






8. 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






9. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






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






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






12. 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






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






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






15. __________________cards report computer errors and conflicts at POST.






16. The one bootable partition.






17. 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.






18. Temporary drop in AC power.






19. 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






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






21. This is how the BIOS communicates errors during POST






22. 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.






23. 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.






24. 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






25. The ________________makes sure the computer meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process.






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






27. 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.






28. 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.






29. 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






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






31. 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.






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






33. 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.






34. Another name for the primary volume.






35. 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.






36. 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.






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






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






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






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






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






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






43. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






44. 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?






45. 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






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






47. 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






48. 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.






49. 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.






50. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.
