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






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






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






4. 20-pin or 24-pin internal power supply connector.






5. 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.






6. 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.






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






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






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






10. 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.






11. 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






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






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






14. 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.






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






16. Standard computer case form factor for modern computers.






17. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






20. __________________cards report computer errors and conflicts at POST.






21. Used to repair and reinstall Windows






22. 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.






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






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






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






26. 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.






27. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






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






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






30. 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.






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






32. The one bootable partition.






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






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






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






36. 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.






37. 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






38. Another name for the primary volume.






39. 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.






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






41. 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.






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






43. 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.






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






45. A___________________can be used to test a USB port.






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