discussed below. It must be understood that this technology is evolving rapidly and that the specific devices that are provided as examples are likely to be upgraded inoperational characteristicsor to be replaced altogether in the near future.
While some forms of secondary memory are internally based, there are also secondary storage devices that are external in nature. External storage devices (also called auxiliary storage devices) can be easily unplugged and used with other operating systems, and offer non-volatile storage: HDDs Floppy...
Non-volatile semiconductor memory is also used for secondary storage in various advanced electronic devices and specialized computers. Examples of semiconductor memory include static random access memory (RAM), which relies on transistors, and dynamic random access memory, which uses capacitors to store ...

Secondary storage is the largest and slowest form of memory. Hard disk drives and CD-ROM drives are examples of secondary storage. These days secondary storage may vary from 600 MB to 60 GB. 1.3.3.2 Width The memory width is the number of bits the memory returns on each access—typically...

Each of the national language versions available from the program library (primary or secondary) include cultural- and language-dependent system values for that particular language. Date format, date and time separators, code page and character set, and keyboard types are examples. The system values...
