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






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






3. 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.






4. 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.






5. 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.






6. 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






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






8. 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.






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






10. Windows Vista technology that supports a hybrid drive.






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






12. 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






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






14. 20-pin or 24-pin internal power supply connector.






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






16. 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:






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






18. Another name for the primary volume.






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






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






21. A___________________can be used to test a USB port.






22. POST means __________________.






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






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






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






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






27. 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.






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






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






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






31. 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






32. 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.






33. Temporary drop in AC power.






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






35. Used to repair and reinstall Windows






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






37. 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.






38. 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.






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. 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.






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






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






43. 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






44. 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.






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






46. Media through which data is transferred from one part of a computer to another. The bus can be compared to a highway on which data travels within a computer.






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






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