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






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






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






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






5. 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.






6. Standard computer case form factor for modern computers.






7. A________________CD can be used to boot a system and repair or reinstall Windows.






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






9. 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.






10. 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:






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






12. 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.






13. 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.






14. 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.






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






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






17. 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.






18. 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.






19. 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






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






21. 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






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






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






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






25. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






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






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






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






29. 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?






30. 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






31. Temporary drop in AC power.






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






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






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






35. 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.






36. 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.






37. 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.






38. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi






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






41. 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.






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






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






44. Another name for the primary volume.






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






46. 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






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






48. 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.






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






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