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






2. 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:






3. 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.






4. 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






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






6. 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.






7. 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.






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






9. A hard drive whose disk controller is integrated into the drive - eliminating the need for a controller cable and thus increasing speed - as well as reducing price.






10. 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






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






12. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






13. The one bootable partition.






14. 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.






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. 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.






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






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






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






20. 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.






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






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






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 nonprofit organization dedicated to creating trade and communications standards.






25. 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.






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






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






28. 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






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






30. 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.






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






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






33. 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.






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






35. 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






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






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






38. 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






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






40. 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.






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






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






43. 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






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






45. 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.






46. This is how the BIOS communicates errors during POST






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






48. Network with each computer






49. 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.






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