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. __________________cards report computer errors and conflicts at POST.






2. POST means __________________.






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






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






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






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






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






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






9. This is how the BIOS communicates errors during POST






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






11. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






12. 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






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






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






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






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






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






18. 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?






19. 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.






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






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






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






23. 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






24. 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?






25. 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.






26. 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.






27. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






28. 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.






29. 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.






30. Temporary drop in AC power.






31. 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






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






33. 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






34. 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.






35. 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.






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






37. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






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






39. Used to repair and reinstall Windows






40. 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.






41. 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.






42. 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.






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






44. Standard computer case form factor for modern computers.






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






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






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






48. 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.






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






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