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. Fastener used to bundle cables inside and outside of a computer.






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






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






4. 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:






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






6. The one bootable partition.






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






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






9. 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.






10. 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.






11. A________________CD can be used to boot a system and repair or reinstall Windows.






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






13. 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






14. 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.






15. POST means __________________.






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. 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.






18. A___________________can be used to test a USB port.






19. 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.






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






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






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






23. Windows Vista technology that supports a hybrid drive.






24. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






26. Network with each computer






27. 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






28. 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.






29. 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.






30. 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






31. Standard computer case form factor for modern computers.






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






33. Command used to check the integrity of files and folders on a hard drive by scanning the disk surface for physical errors.






34. 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.






35. 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.






36. 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






37. 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






38. __________________cards report computer errors and conflicts at POST.






39. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






40. 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.






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. 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.






43. 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?






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