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 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.






2. __________________cards report computer errors and conflicts at POST.






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






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






5. 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






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






7. 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.






8. Windows Vista technology that supports a hybrid drive.






9. 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.






10. 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.






11. Another name for the primary volume.






12. 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






13. 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






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






15. A___________________can be used to test a USB port.






16. 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.






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






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






19. 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.






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. 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:






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






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






24. 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.






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






26. 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.






27. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






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






29. 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.






30. 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.






31. 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.






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






33. 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?






34. 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.






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






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






37. POST means __________________.






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






39. 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






40. Temporary drop in AC power.






41. 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






42. 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.






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






44. 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.






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






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






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






48. 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.






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






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