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






2. A___________________can be used to test a USB port.






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






4. 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.






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






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






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






8. 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






9. 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?






10. 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.






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






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






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






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






15. POST means __________________.






16. 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.






17. 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






18. 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






19. 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.






20. 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.






21. Standard that specifies full SATA cabling for external disks.






22. 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.






23. 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.






24. A drive with no moving parts. Uses nonvolatile flash memory.






25. Windows Vista technology that supports a hybrid drive.






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






27. 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?






28. 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.






29. 20-pin or 24-pin internal power supply connector.






30. 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






31. 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.






32. __________________cards report computer errors and conflicts at POST.






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






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






35. This is how the BIOS communicates errors during POST






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






38. 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.






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






40. Involves restarting the computer by pressing the on/off switch. Stressful on computers.






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






42. 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.






43. 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.






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






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






46. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






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






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






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






50. Temporary drop in AC power.
