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






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






3. 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.






4. 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.






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






6. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






7. Memory that does not lose its data when the power is turned off.






8. 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






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






10. A number from 0 to 15 assigned to each SCSI device attached to the daisy chain.






11. 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.






12. POST means __________________.






13. Temporary drop in AC power.






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






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






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






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






18. 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






19. 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






20. 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:






21. A___________________can be used to test a USB port.






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






23. 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.






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






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






26. 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.






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






28. Used to repair and reinstall Windows






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






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






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






32. 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.






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






34. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






35. 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.






36. 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.






37. 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






38. 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






39. 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.






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






41. __________________cards report computer errors and conflicts at POST.






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






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






44. Network with each computer






45. 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.






46. 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.






47. 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.






48. 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.






49. Standard computer case form factor for modern computers.






50. 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.
