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






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






3. Windows Vista technology that supports a hybrid drive.






4. 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.






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






6. __________________cards report computer errors and conflicts at POST.






7. 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.






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






9. 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






10. 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.






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






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






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






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






15. 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.






16. Standard computer case form factor for modern computers.






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






18. 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






19. 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.






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






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






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






23. 20-pin or 24-pin internal power supply connector.






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






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






26. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






27. 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






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






29. 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.






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






31. A________________CD can be used to boot a system and repair or reinstall Windows.






32. A___________________can be used to test a USB port.






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






34. 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.






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






36. 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.






37. 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?






38. 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.






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






40. 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.






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






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






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






44. 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.






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






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






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






48. 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.






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






50. 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?
