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






2. 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.






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






4. 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






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






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






7. 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.






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






9. A___________________can be used to test a USB port.






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






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






12. 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.






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






14. 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.






15. 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.






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






17. 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.






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






19. 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.






20. 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.






21. 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






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






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






24. 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






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






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






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






28. 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.






29. 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






30. 20-pin or 24-pin internal power supply connector.






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






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






33. 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.






34. Troubleshooting tool that allows the computer to boot from a disk when the hard drive will not boot.






35. 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.






36. In Windows XP - you should choose the _______________setting for updates.






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






38. 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.






39. 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.






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






41. 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






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






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






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






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






46. 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.






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






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






49. List managed by a network administrator that itemizes what a user is permitted to access and the type of access granted.






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