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. 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






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






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






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






5. Standard computer case form factor for modern computers.






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






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






8. 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






9. Troubleshooting tool that allows the computer to boot from a disk when the hard drive will not boot.






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






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






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






13. 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.






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






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






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






17. 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






18. 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:






19. 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.






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






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






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






23. 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






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






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






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






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






28. The ________________makes sure the computer meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process.






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






30. 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






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






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






33. This is how the BIOS communicates errors during POST






34. 20-pin or 24-pin internal power supply connector.






35. 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.






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






38. Another name for the primary volume.






39. 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.






40. 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






41. 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.






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






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






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






45. 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






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






47. 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.






48. 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.






49. 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.






50. 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.
