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






2. This is how the BIOS communicates errors during POST






3. 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.






4. 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.






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






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






7. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






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






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






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






13. 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






14. 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.






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






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






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






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






19. 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






20. POST means __________________.






21. A unit of measure that describes the size of a data file - the amount of space on a disk or other storage medium - or the amount of data being sent over a network. One byte consists of 8 bits of data.






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






23. 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.






24. 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.






25. A single hard drive that works independently of other hard drives.






26. 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?






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






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






29. 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.






30. Temporary drop in AC power.






31. 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.






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






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






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






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






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






38. 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.






39. 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.






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






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






42. 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.






43. 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.






44. 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.






45. 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.






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






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






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






49. 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.






50. 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.
