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






2. Temporary drop in AC power.






3. 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.






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






5. How do you change a computer's Boot Sequence?






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






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






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






9. 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.






10. 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






11. 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.






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






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






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






15. 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.






16. 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.






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






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






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






20. 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.






21. 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






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






23. An ATAPI cabling method that uses a narrower and more reliable cable than the 80-conductor cable.






24. 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.






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






26. Used to repair and reinstall Windows






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. 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






29. 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.






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






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






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






33. 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.






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






35. 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.






36. 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






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






38. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






39. 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.






40. 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.






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






42. 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:






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






44. Standard computer case form factor for modern computers.






45. Command used to check the integrity of files and folders on a hard drive by scanning the disk surface for physical errors.






46. 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.






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






48. POST means __________________.






49. 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






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