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.

2. 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?






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






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






5. A___________________can be used to test a USB port.






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

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






9. Network with each computer






10. 20-pin or 24-pin internal power supply connector.






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






12. 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






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






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






15. 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






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






17. The one bootable partition.






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






19. 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.






20. 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.






21. 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.






22. Another name for the primary volume.






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






24. 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:






25. 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






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






28. 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






29. 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.






30. A computer's ability to respond to a fault or catastrophe - such as a hardware failure or power outage - so that data is not lost.






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






32. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






34. Temporary drop in AC power.






35. 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.






36. Windows Vista technology that supports a hybrid drive.






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






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






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






40. 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.






41. 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.






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






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






44. 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.
