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. 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.






2. Used to repair and reinstall Windows






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






4. In Windows XP - you should choose the _______________setting for updates.






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. 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






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






8. 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.






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






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






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






12. 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






13. 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.






14. POST means __________________.






15. 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






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






17. Standard computer case form factor for modern computers.






18. 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.






19. 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.






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






21. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






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






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






24. __________________cards report computer errors and conflicts at POST.






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






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






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






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






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






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






32. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






34. 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.






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






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






37. 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






38. 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.






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






40. A___________________can be used to test a USB port.






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






42. 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?






43. 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






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






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






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






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






48. 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.






49. When two hard drives are configured as a single volume.






50. 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.
