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. 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.






2. 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.






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






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






5. 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.






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






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






8. In Windows XP - you should choose the _______________setting for updates.






9. 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.






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






11. 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.






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






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






14. 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.






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






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






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






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






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






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






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






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






23. __________________cards report computer errors and conflicts at POST.






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






25. 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






26. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






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






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






29. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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. 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.






32. 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.






33. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






34. 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






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






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. Standard computer case form factor for modern computers.






38. A___________________can be used to test a USB port.






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. 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.






41. 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.






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






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






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






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






46. 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
