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






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






4. 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






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






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






7. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






8. 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.






9. __________________cards report computer errors and conflicts at POST.






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






11. 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






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






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






14. In Windows XP - you should choose the _______________setting for updates.






15. 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.






16. This is how the BIOS communicates errors during POST






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






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






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






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






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






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






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






24. 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.






25. 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






26. 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.






27. 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.






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






29. The 12-bit wide - one-column file allocation table for a floppy disk - containing information about how each cluster or file allocation unit on the disk is currently used.






30. To power up a computer from the off position.






31. 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.






32. 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






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






34. 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






35. 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.






36. 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






37. 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.






38. The one bootable partition.






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






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






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






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






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






44. 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






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






46. 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.






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






48. 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:






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






50. 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.
