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. 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.






2. 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:






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






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






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






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






7. 20-pin or 24-pin internal power supply connector.






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






9. A transfer mode used by devices - including the hard drive - to transfer data to memory without involving the CPU.






10. Temporary drop in AC power.






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






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






13. 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.






14. 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






15. 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.






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






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






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






19. __________________cards report computer errors and conflicts at POST.






20. 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?






21. 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






22. 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.






23. 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.






24. Standard computer case form factor for modern computers.






25. 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.






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






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






28. 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






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






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






31. 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






32. 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.






33. 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.






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






35. A number from 0 to 15 assigned to each SCSI device attached to the daisy chain.






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






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






38. 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.






39. 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.






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






41. 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.






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. This is how the BIOS communicates errors during POST






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






45. 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.






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






47. 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






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






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