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






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






3. __________________cards report computer errors and conflicts at POST.






4. 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






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






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






7. 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?






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






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






10. 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.






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






12. 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






13. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






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






15. Standard computer case form factor for modern computers.






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






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






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






19. 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.






20. 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.






21. 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.






22. 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.






23. A___________________can be used to test a USB port.






24. 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.






25. 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






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






27. Used to repair and reinstall Windows






28. 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.






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






30. 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.






31. 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






32. Network with each computer






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






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






35. 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.






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






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






38. The one bootable partition.






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






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






41. 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.






42. 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






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






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






45. 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.






46. Another name for the primary volume.






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






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






49. 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






50. 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.
