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






2. 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.






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






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






5. Windows Vista technology that supports a hybrid drive.






6. 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






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






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






9. 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.






10. 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.






11. 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.






12. 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.






13. 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.






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






15. 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






16. 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?






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






18. 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






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






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






22. 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.






23. 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






24. A single hard drive that works independently of other hard drives.






25. 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?






26. 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:






27. 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






28. 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






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






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






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






32. 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.






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






34. 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.






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






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






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






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






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






40. 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.






41. This is how the BIOS communicates errors during POST






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






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






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






45. 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.






46. A___________________can be used to test a USB port.






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






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






49. Network with each computer






50. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.
