You want some definition about Static Partitioned Allocation..?


What is Static Partitioned Allocation ?

          Static Partitioned allocation refers to the process of allocating memory at compile-time before the associated program is executed, unlike dynamic memory allocation or automatic memory allocation where memory is allocated as required at run-time.
         Static allocation is memory that has been set aside for an application when it is first loaded. This section of memory is kept to be only used with that application, and is made available again once the program is closed.    
  
            

Formula to get Size,Memory used and Unused:

       Size                =    Memory Unused + Unused Memory
Memory Unused   =   Size - Unused Memory
Unused Memory   =   Size + Memory Unused 


Here are some Examples of Static:

a.)  
Residence OS = 412kb
     Total Capacity = 3024kb


Initial state of Memory

b.)  Residence OS = 512kb
     Total Capacity = 3051kb


Initial state of Memory

c.)  Residence OS = 250kb
     Total Capacity = 2058kb
