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. 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






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






3. 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






4. 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






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. 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






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






8. Temporary drop in AC power.






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






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






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






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






13. 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.






14. 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.






15. Used to repair and reinstall Windows






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






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






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. The one bootable partition.






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






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






22. 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.






23. 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.






24. 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?






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






26. 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?






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






28. Another name for the primary volume.






29. POST means __________________.






30. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






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






32. Standard computer case form factor for modern computers.






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






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






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






36. 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






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






38. 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.






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






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






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






42. 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.






43. 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.






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






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






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






47. 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:






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