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. Media through which data is transferred from one part of a computer to another. The bus can be compared to a highway on which data travels within a computer.






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






3. 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?






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






5. 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.






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






7. 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.






8. Used to repair and reinstall Windows






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






10. 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






11. 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.






12. 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






13. 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






14. This is how the BIOS communicates errors during POST






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






16. 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.






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






18. __________________cards report computer errors and conflicts at POST.






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






20. Network with each computer






21. 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.






22. 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:






23. Another name for the primary volume.






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






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






26. 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.






27. 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.






28. 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






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






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. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






33. 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






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






35. 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.






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






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






38. 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?






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






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






41. 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






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






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






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






45. 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.






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






47. 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.






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






49. 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.






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