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






2. Windows Vista technology that supports a hybrid drive.






3. 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






4. 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.






5. 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.






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






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






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






9. 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.






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






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






12. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






13. 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.






14. 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






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






16. 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.






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






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






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






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






21. 20-pin or 24-pin internal power supply connector.






22. 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.






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






24. 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






25. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






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






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






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






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






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






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






32. 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






33. 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.






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






35. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






37. 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:






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






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






40. 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.






41. 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.






42. 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






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






44. 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.






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






46. 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.






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






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






49. 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






50. 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.
