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. 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.






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






3. 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






4. 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?






5. 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.






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






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






8. 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.






9. 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






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






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






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






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






14. Memory that does not lose its data when the power is turned off.






15. 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






16. Temporary drop in AC power.






17. 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.






18. 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.






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






20. 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






21. 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.






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






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






24. 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






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






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






27. 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.






28. 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.






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






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






31. 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.






32. 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.






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






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






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






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






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






38. Another name for the primary volume.






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






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






41. 20-pin or 24-pin internal power supply connector.






42. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






44. 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.






45. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






46. 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.






47. 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






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






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






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