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. 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.






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






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






4. This is how the BIOS communicates errors during POST






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






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






7. 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






8. 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.






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






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






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






12. Network with each computer






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






14. 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.






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






16. 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






17. 20-pin or 24-pin internal power supply connector.






18. A___________________can be used to test a USB port.






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






20. POST means __________________.






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






22. __________________cards report computer errors and conflicts at POST.






23. 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.






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






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






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






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






28. Standard computer case form factor for modern computers.






29. 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






30. 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.






31. 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






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






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






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






35. 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.






36. 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.






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






38. 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?






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






40. 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.






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






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






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






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






45. 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.






46. Another name for the primary volume.






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






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






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






50. 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.
