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 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






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






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






4. A nonprofit organization dedicated to creating trade and communications standards.






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






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






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






8. 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.






9. 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






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






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






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






14. The process - you specify the size of the partition and what file system it will use.






15. Layer 7 of the OSI reference model. This layer provides services to application processes such as electronic mail - file transfer - and terminal emulation that are outside of the OSI model. The application layer identifies and establishes the availab






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






17. 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.






18. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






19. Is a type of drive imaging. It duplicates data on one drive to another drive and is used for fault tolerance.






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






21. 20-pin or 24-pin internal power supply connector.






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






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






24. 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.






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






26. 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.






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






28. Another name for the primary volume.






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






30. 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






31. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






32. 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.






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






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






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






36. 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?






37. 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.






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






39. 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






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






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






43. 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.






44. __________________cards report computer errors and conflicts at POST.






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