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






2. 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.






3. 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.






4. 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?






5. 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.






6. Standard computer case form factor for modern computers.






7. 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.






8. Network with each computer






9. 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






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






11. 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.






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






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






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






15. You should write down or backup changes to CMOS/BIOS setup ____________________.






16. 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.






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






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






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






20. 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.






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






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






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






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






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






26. 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.






27. __________________cards report computer errors and conflicts at POST.






28. 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






29. 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






30. 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.






31. A___________________can be used to test a USB port.






32. 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.






33. Windows Vista technology that supports a hybrid drive.






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






35. 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






36. 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.






37. 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.






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






39. Another name for the primary volume.






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






41. 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.






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






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






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






45. 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






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