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. Windows Vista technology that supports a hybrid drive.






2. 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






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






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






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






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






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






8. 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






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






10. This tool can be used to test a USB port.






11. 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






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






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. 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.






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






16. Fastener used to bundle cables inside and outside of a computer.






17. Network with each computer






18. 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






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






20. Used to repair and reinstall Windows






21. 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.






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






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






24. 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.






25. 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.






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






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






28. 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.






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






30. 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






31. 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.






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






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






34. 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:






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






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






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






38. 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.






39. 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.






40. A___________________can be used to test a USB port.






41. 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.






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






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






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






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






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






47. This is how the BIOS communicates errors during POST






48. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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