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. Temporary drop in AC power.






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






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






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






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






7. 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






8. 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






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






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






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






12. 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.






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






14. 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






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






16. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






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






18. POST means __________________.






19. 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






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






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






22. Another name for the primary volume.






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






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






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






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






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






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






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






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






31. 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






32. __________________cards report computer errors and conflicts at POST.






33. 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






34. 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:






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






36. 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.






37. 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.






38. 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.






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






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






41. 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.






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






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






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






45. 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.






46. 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.






47. 20-pin or 24-pin internal power supply connector.






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






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






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