7.1.10+Logical+&+Physical+Data+Organization

=**__Explain how the Logical Organization of Data differs from Physical Organization__**=

**__Physical Structure:__**

 * Physical data is stored linearly in the RAM
 * Those linear pieces of data are stored in Bits
 * On a form of Secondary Storage is simply stored in linear form and is encoded in a certain way

**__Logical Structures__**

 * In RAM logic is represented in form of data structures
 * There are different form of searching this:
 * Arrayed Structure uses a linear search through the RAM
 * Linked Lists follow a similar pattern of the Physical Structure
 * Binary Trees where the data is stored and linked differently


 * On Secondary Storages files are accessed through an index

To summarise: Physical Storage is always linear and Logical Structures are imposed over this suing some method of organisation.
