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. 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.






2. 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.






3. Another name for the primary volume.






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






5. POST means __________________.






6. 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






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






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






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






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






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






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






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






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






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






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






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






19. The one bootable partition.






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






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






22. A unit of measure that describes the size of a data file - the amount of space on a disk or other storage medium - or the amount of data being sent over a network. One byte consists of 8 bits of data.






23. 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?






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






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






26. 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.






27. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






28. 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.






29. 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:






30. 20-pin or 24-pin internal power supply connector.






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






32. 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.






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






34. Temporary drop in AC power.






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






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






37. 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






38. Network with each computer






39. 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






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






41. 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.






42. 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






43. 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.






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






45. 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.






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






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






48. 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.






49. 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.






50. 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
