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. The one bootable partition.






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






3. 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.






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






5. 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.






6. 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






7. 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.






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






9. Windows Vista technology that supports a hybrid drive.






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. 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.






12. 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.






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






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






15. Network with each computer






16. Temporary drop in AC power.






17. This is how the BIOS communicates errors during POST






18. 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.






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






20. Used to repair and reinstall Windows






21. Standard computer case form factor for modern computers.






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






23. 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.






24. 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






25. 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?






26. Another name for the primary volume.






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






28. 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






29. 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.






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






31. 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.






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






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






34. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






35. 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.






36. 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.






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