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. 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






2. __________________cards report computer errors and conflicts at POST.






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






4. 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.






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






6. Standard computer case form factor for modern computers.






7. 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






8. Temporary drop in AC power.






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






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






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






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






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






14. 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.






15. 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.






16. 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.






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






18. The one bootable partition.






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






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






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






22. 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.






23. Windows Vista technology that supports a hybrid drive.






24. 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.






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






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






27. POST means __________________.






28. 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.






29. Five possible questions that should be asked of a user who is experiencing computer problems: What had just happened? What recent changes did the user make? When did the computer __________? What error message do you see?






30. 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.






31. 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:






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






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






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






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






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






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






38. 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






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






40. 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.






41. 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.






42. 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






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






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






45. 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.






46. 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.






47. 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.






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






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






50. 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.
