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






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






3. 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.






4. A___________________can be used to test a USB port.






5. 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.






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






7. 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.






8. 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.






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






10. 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.






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






12. 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.






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






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






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






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






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






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






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






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






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






25. 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.






26. 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






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






28. Another name for the primary volume.






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






30. POST means __________________.






31. 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






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






33. 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.






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






35. __________________cards report computer errors and conflicts at POST.






36. 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.






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






38. Windows Vista technology that supports a hybrid drive.






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






40. 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.






41. 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.






42. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






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






44. Network with each computer






45. 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.






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






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






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