  Model of Computation Model of computation is a model which describes how an output of a mathematical function is computed given an input. Example:  A model describes how units of computations, memories, and communications are organized. Mathematical Function (X=A+B) Input: A: 7 B: 3 Output: X= 10

   The computationalcomplexity of an algorithm can be measured given a model of computation.  Using a model allows studying the performance of algorithms independently of the variations that are specific to particular implementations and specific technology. Input:A and B are variables, Output: X are variables Case 1:A=7 and B=3 then X=10 Case 2:A=2 and B=5 then X=7 Case 2:A=6 and B=4 then X=11 A,B and X are variable NowAllVariable are required to declared, means required to save value Memory

   All variableare having on size/space. Ex: int- 2byte float- 4byte char -1 byte variable are reserved some space in specific location in the memory. B X A Memory Unit 2000 3000 1000 Location Of Variable
