    Part IITrue/False Questions 21. The process of saving information to a secondary storage device is referred to as embedding. True False 22. Hard disks use tracks, sectors, and cylinders to store files. True False 23. A head crash occurs typically on a floppy disk when it makes contact with particles on its surface. False 24. Disk caching improves hard-disk performance by compressing files. True False 25. A digital versatile disk (DVD) is about the same size as a CD-ROM, stores more data than a CD-ROM, and

    provides much faster access to the data. True False 26. Blu-Ray discs have a capacity less than DVD discs. True False 27. USB drives (U) are solid-state storage devices which have no moving parts. True False 28. Internet hard drives give users unlimited storage capacity. True False 29. Mass storage devices are primary storage devices designed to store large amounts of data for an

    organization. True False (Mass storage) 30. Flash memory cards are a form of a solid-state storage device that is widely used in digital camera. True Part III: Fill-In-The-Blank questions 31. Tracks are divided into invisible wedge-shaped sections called sectors 32. Each sector can store up to 512 bytes or characters. 33. Improving hard-disk performance by storing anticipated data in a high-speed memory location is called

    disk cashing . 34. Due to its expanded storage capability, fast access speed, and high reliability RAID is often used by

    Internet servers and large organizations. 35. CD-ROM is an example of a(n) optical type of storage medium.

    Part IV: Open-Ended Questions 36. Describe the three basic types of CDs.

    The three basic types of CDs are: (1) Read onlyCD-ROM - Read only means it cannot be written on or erased by the user. (2) Write onceCD-R - which stands for CD-recordable, can be written to once. After that they can be read many times but cannot be written on or erased. (3) RewriteableCD-RW stands for compact disc rewritable. Also known as erasable optical discs, these disks are very similar to CD-Rs except that the disk surface is not permanently altered when data is recorded.

    37. Explain the advantages and the disadvantages of having an Internet hard drive. Advantages of Internet hard drives include low cost and the flexibility to access information from any location using the Internet. Disadvantages include slow access speed. And sometimes non-availability () and the security procedures of the service site should be considered. Because of these limitations, Internet hard drives are typically used as a specialized secondary storage device and not for storing highly personalized or sensitive information.

    38. Contrast sequential access () with direct access (). Sequential storage () stores data one record after another. Cassette tapes () are an example of storage that must be accessed sequentially. In order to search for a specific record you must search sequentially until the record is found. Direct access media allow records to be retrieved in random order. CDs and floppy diskettes provide direct access.
