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






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






3. 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.






4. 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.






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






6. 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






7. 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.






8. Temporary drop in AC power.






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






10. 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.






11. Used to repair and reinstall Windows






12. 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?






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






14. 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






15. 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.






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






17. 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.






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






19. 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.






20. A___________________can be used to test a USB port.






21. 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






22. 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.






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






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






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






26. The one bootable partition.






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






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






29. 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






30. 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.






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






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






33. 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.






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






35. 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






36. Another name for the primary volume.






37. 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:






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






39. A transfer mode that uses the CPU to transfer data from the hard drive to memory. This mode is slower than DMA mode.






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






41. __________________cards report computer errors and conflicts at POST.






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






43. A nonprofit organization dedicated to creating trade and communications standards.






44. 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.
