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. 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.






2. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






5. POST means __________________.






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






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. 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.






9. 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.






10. 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






11. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






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






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






14. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






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. Another name for the primary volume.






17. 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.






18. The 12-bit wide - one-column file allocation table for a floppy disk - containing information about how each cluster or file allocation unit on the disk is currently used.






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






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






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






22. 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






23. 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.






24. 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






25. Protocol suite to network Macintosh computers. It is comprised of a comprehensive set of protocols that span the seven layers of the OSI reference model.






26. Temporary drop in AC power.






27. Windows Vista technology that supports a hybrid drive.






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






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






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






31. Network with each computer






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






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






34. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






35. 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.






36. The one bootable partition.






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






38. List managed by a network administrator that itemizes what a user is permitted to access and the type of access granted.






39. 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.






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






41. 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.






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






43. 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.






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






45. 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.






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






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






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






49. 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






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