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






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






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






5. Network with each computer






6. Standard computer case form factor for modern computers.






7. A___________________can be used to test a USB port.






8. 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.






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






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






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






12. 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.






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






14. Temporary drop in AC power.






15. Used to repair and reinstall Windows






16. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






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






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






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






20. This is how the BIOS communicates errors during POST






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






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. 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.






24. 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






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






26. The one bootable partition.






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






28. POST means __________________.






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






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. Another name for the primary volume.






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






33. Command used to check the integrity of files and folders on a hard drive by scanning the disk surface for physical errors.






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






35. 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.






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






37. 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.






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






39. 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.






40. 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.






41. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






42. 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






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






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






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






46. 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.






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






48. 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






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






50. 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
