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






3. POST means __________________.






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. 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.






6. 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.






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






8. The one bootable partition.






9. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






11. 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.






12. __________________cards report computer errors and conflicts at POST.






13. Network with each computer






14. 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.






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






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






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






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






19. 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.






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






21. 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.






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






23. 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.






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






25. Temporary drop in AC power.






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






27. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






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






29. 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.






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






31. 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.






32. 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






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 drive that uses both solid state and magnetic technologies.






35. 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.






36. How do you change a computer's Boot Sequence?






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






38. 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






39. 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.






40. 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.






41. 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.






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






43. Another name for the primary volume.






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






45. Used to repair and reinstall Windows






46. 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.






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






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






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






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