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






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






3. 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.






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






5. 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.






6. 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






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






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






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






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






11. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






12. 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.






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






14. 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.






15. 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.






16. 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.






17. A Data Link layer device that connects and passes frames between two network segments. The frames are filtered and forwarded using MAC addresses.






18. 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






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






20. 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






21. 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.






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






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






24. 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.






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






26. Temporary drop in AC power.






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






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






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






30. 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?






31. 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.






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






33. This is how the BIOS communicates errors during POST






34. 20-pin or 24-pin internal power supply connector.






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






36. Four Main Parts of the boot process: 1. BIOS checks hardware through POST. 2. The ___________ searches for and loads an OS. 3. The OS configures the system and completes its own loading. 4. The user executes application software.






37. 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.






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






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






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






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






43. 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.






44. The one bootable partition.






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






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






47. 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.






48. 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.






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






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