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. Network with each computer






2. 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.






3. 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.






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






5. The process - you specify the size of the partition and what file system it will use.






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






7. 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.






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






9. Standard computer case form factor for modern computers.






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






11. __________________cards report computer errors and conflicts at POST.






12. Used to repair and reinstall Windows






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






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






15. 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.






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






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






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






19. 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?






20. 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.






21. This is how the BIOS communicates errors during POST






22. 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.






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






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






25. 20-pin or 24-pin internal power supply connector.






26. 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






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






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






29. 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.






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






31. 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






32. 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.






33. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






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






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






38. 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.






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






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






41. The one bootable partition.






42. 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.






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






44. 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






45. 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.






46. A fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus.






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






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. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi






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