Extract from Course Notes:

In this age of convenience, new and varied storage methods are being developed to enable us to quickly and easily transfer information between computers and other electronic devices.

The need for cheap, reliable, fast, high capacity, portable storage is at an all time high and electronic manufacturers have responded with a variety of solutions.

CD\'s, minidisks, tapes and DVD\'s are all portable storage mediums that most people are familiar with. The DVD format squeezes more data onto a single disc than is possible with a regular CD. CD-ROMs can fit about 700MB onto a disc, whereas DVDs can fit greater than 17 gigabytes (17GB). Because of their large memory capacity, DVDs are generally used to store MPEG file types such as movies, and high-resolution video games. Also, business applications are increasingly being stored on a single DVD that would otherwise have required multiple CDs. Another commonly used yet generally overlooked form of storage is \'Flash Memory\'. Flash memory allows a huge amount of data to be stored reliably on very small \'cards\', offering a viable alternative to the common disk or CD. Mobile phones use flash memory cards the size of a postage stamp to store information such
