Storage Structures

It describes how the data items are stored in the memory.

• It provides a map of how data elements are allocated memory space
• Elements are stored in conseccutive or in disjoint storage locations
• Each location is identified by unique number called memory address
• The figure contigous allocation of storage space to set of characters

To access any element, the address of the first element is needed

 

• As shown in the figure character A, B, C are stored in non-contigous locations
• Each character A is followed by integer 3000, which is the storage address of character B.
