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. POST means __________________.






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






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






4. 20-pin or 24-pin internal power supply connector.






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






6. 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.






7. Network with each computer






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






9. 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.






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






11. 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.






12. 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.






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. Windows Vista technology that supports a hybrid drive.






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






16. 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.






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






18. 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.






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






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






21. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






22. 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.






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






24. __________________cards report computer errors and conflicts at POST.






25. 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.






26. This is how the BIOS communicates errors during POST






27. A___________________can be used to test a USB port.






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






29. 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






30. 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.






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






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






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






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






35. One or more sectors that constitute the smallest unit of space on a disk for storing data (also referred to as a file allocation unit). Files are written to a disk as groups of whole clusters.






36. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






37. 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.






38. 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






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






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






41. 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:






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






43. 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






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






45. 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.






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






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






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






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






50. 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.
