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






2. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






3. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






4. 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.






5. 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.






6. 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






7. 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.






8. Another name for the primary volume.






9. 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






10. 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.






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






12. 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.






13. POST means __________________.






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






15. 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






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






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






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






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






20. 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.






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






22. The one bootable partition.






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






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






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






26. 20-pin or 24-pin internal power supply connector.






27. 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.






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






29. A___________________can be used to test a USB port.






30. A drive with no moving parts. Uses nonvolatile flash memory.






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






32. 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?






33. 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.






34. 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






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






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






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






38. The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. This device controls communication between the SCSI bus and the PC.






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






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






41. 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






42. Windows Vista technology that supports a hybrid drive.






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






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






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






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






47. 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






48. 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.






49. 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.






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