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






2. 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






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






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






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






6. __________________cards report computer errors and conflicts at POST.






7. 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.






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






9. 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.






10. 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.






11. 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.






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






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






14. 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?






15. 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






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






17. 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.






18. 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.






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






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






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






22. Windows Vista technology that supports a hybrid drive.






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






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






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






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






27. 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






28. 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.






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






30. Network with each computer






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






32. To power up a computer from the off position.






33. 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.






34. 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.






35. 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.






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