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. 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.






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






3. 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.






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






5. 20-pin or 24-pin internal power supply connector.






6. 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.






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






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






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






10. 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.






11. 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.






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






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






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






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






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






17. 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.






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






19. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






22. 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.






23. 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.






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






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






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






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






28. 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






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






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






31. Standard computer case form factor for modern computers.






32. 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






33. Network with each computer






34. A___________________can be used to test a USB port.






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






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






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






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






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






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






41. 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






42. 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.
