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. 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.






2. 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.






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






4. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






5. 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.






6. 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






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






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






9. The one bootable partition.






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






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






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






13. 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






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






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






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






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






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






19. 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.






20. 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.






21. 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.






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






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






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






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






26. Standard computer case form factor for modern computers.






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






28. 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.






29. 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






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






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






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






33. 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.






34. This can be divided into one or more logical drives. Each logical drive is assigned a drive letter (such as drive G:) and is formatted using its own file system.






35. 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.






36. 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.






37. 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






38. 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






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






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






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






42. 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.






43. 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.






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






45. 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






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






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






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






49. 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.






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