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






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






3. A hard drive whose disk controller is integrated into the drive - eliminating the need for a controller cable and thus increasing speed - as well as reducing price.






4. 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.






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






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






7. POST means __________________.






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






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






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






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






13. 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






14. Standard computer case form factor for modern computers.






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






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






17. 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.






18. Another name for the primary volume.






19. 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






20. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






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






22. 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.






23. This is how the BIOS communicates errors during POST






24. 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.






25. 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






26. 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.






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






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






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






30. 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






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






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






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






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






35. 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.






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






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






38. 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.






39. Temporary drop in AC power.






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






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






42. __________________cards report computer errors and conflicts at POST.






43. 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.






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






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






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






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






48. A___________________can be used to test a USB port.






49. 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.






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