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. 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.






2. Media through which data is transferred from one part of a computer to another. The bus can be compared to a highway on which data travels within a computer.






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






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






5. 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






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






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






8. 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.






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






11. 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.






12. Network with each computer






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






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






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






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






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






18. 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.






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






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






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






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






23. 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?






24. 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






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






26. The one bootable partition.






27. __________________cards report computer errors and conflicts at POST.






28. 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.






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






30. 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.






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






32. 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.






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






34. 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.






35. 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






36. POST means __________________.






37. 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?






38. 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.






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






40. 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.






41. 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






42. Temporary drop in AC power.






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






44. 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.






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






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






47. 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.






48. Standard computer case form factor for modern computers.






49. 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.






50. 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.
