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






2. 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.






3. 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.






4. The one bootable partition.






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






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






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






8. POST means __________________.






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






10. 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






11. 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






12. 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.






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






14. 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.






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






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






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






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






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






20. 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.






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






22. 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.






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






24. Standard computer case form factor for modern computers.






25. 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.






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






27. 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






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






29. 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.






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






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






32. 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.






33. 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.






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






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






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






37. 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.






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






39. 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?






40. 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:






41. 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






42. 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






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






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






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. 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.






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






48. A___________________can be used to test a USB port.






49. Temporary drop in AC power.






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