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






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






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






4. 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






5. Network with each computer






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






7. 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.






8. This is how the BIOS communicates errors during POST






9. Temporary drop in AC power.






10. Another name for the primary volume.






11. 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






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






13. 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.






14. 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.






15. 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.






16. 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.






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






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






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






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






21. 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.






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






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






24. 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.






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






26. 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
