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. 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






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






3. 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.






4. 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






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






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






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






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






9. 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






10. 20-pin or 24-pin internal power supply connector.






11. 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.






12. 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.






13. POST means __________________.






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






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






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






17. 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






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






19. 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.






20. __________________cards report computer errors and conflicts at POST.






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






22. 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.






23. Windows Vista technology that supports a hybrid drive.






24. 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.






25. 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






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






27. 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






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






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






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






31. 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






32. 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.






33. 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?






34. 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.






35. 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.






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






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






38. 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






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






40. 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.






41. 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.






42. Backs up user-selected files to tape. This backup does not reset the archive bit.






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






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






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






46. 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.






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






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






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






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