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. Network with each computer






3. Temporary drop in AC power.






4. Windows Vista technology that supports a hybrid drive.






5. Another name for the primary volume.






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






7. 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.






8. Standard computer case form factor for modern computers.






9. 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.






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






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






12. 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.






13. 20-pin or 24-pin internal power supply connector.






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






15. 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.






16. 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






17. 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.






18. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






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






20. 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.






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






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






23. This is how the BIOS communicates errors during POST






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






25. 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:






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






27. 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






28. 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.






29. 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.






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






31. 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






32. 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.






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






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






35. 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.






36. 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.






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






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






39. 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






40. A table on a hard drive or floppy disk that tracks how space on a disk is used to store files.






41. 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.






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






43. 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.






44. 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?






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






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






47. The one bootable partition.






48. A___________________can be used to test a USB port.
