Subject : it-skills
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. Standard that specifies full SATA cabling for external disks.






2. 20-pin or 24-pin internal power supply connector.






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






4. __________________cards report computer errors and conflicts at POST.






5. Network with each computer






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






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






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






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






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. This is how the BIOS communicates errors during POST






12. 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






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






14. 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.






15. 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.






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






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






18. 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.






19. 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?






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






21. 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






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






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






24. 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.






25. A___________________can be used to test a USB port.






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






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. POST means __________________.






29. 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






30. 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.






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






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






33. Standard computer case form factor for modern computers.






34. 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.






35. 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.






36. Speed at which bits are transmitted - usually expressed in bits per second (bps).






37. 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.






38. 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.






39. 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.






40. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






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






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






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






46. 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






47. 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.






48. Windows Vista technology that supports a hybrid drive.






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






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