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. Stripes data across three or more drives and uses parity checking - so that if one drive fails - the other drives can re-create the data stored on the failed drive. Data is not duplicated - and - therefore - THIS makes better use of volume capacity.






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






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






4. 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






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






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






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






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






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






10. 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?






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






12. A___________________can be used to test a USB port.






13. 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.






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






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






16. 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.






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






18. 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






19. 20-pin or 24-pin internal power supply connector.






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






21. 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






22. 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.






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






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






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






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






27. 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.






28. 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:






29. 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.






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






31. 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.






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






33. __________________cards report computer errors and conflicts at POST.






34. Another name for the primary volume.






35. 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.






36. 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.






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






38. 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.






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






40. 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?






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






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






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






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






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






46. 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.
