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






2. 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.






3. 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






4. Temporary drop in AC power.






5. The one bootable partition.






6. In Windows XP - you should choose the _______________setting for updates.






7. 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.






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






9. 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






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






11. 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.






12. 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.






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






14. 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:






15. 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






16. 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






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






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






19. 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.






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






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 drive with no moving parts. Uses nonvolatile flash memory.






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






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






25. 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.






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






27. 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.






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






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






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






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






32. A drive that uses both solid state and magnetic technologies.






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






34. 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.






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






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






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






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






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






40. 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?






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






42. POST means __________________.






43. __________________cards report computer errors and conflicts at POST.






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






46. Standard computer case form factor for modern computers.






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. 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






49. 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.






50. Media through which data is transferred from one part of a computer to another. The bus can be compared to a highway on which data travels within a computer.
