Comparison of 8-bit (8085),16-bit (8086) and 32-bit (80386) microprocessor

Microprocessor is the heart of the computer and the power of microprocessor is depends on the amount of data handled by it. Microprocessor is manufactured into the lightweight IC structure. So mostly when the study goes on about revolution of microprocessors or something about its family the question is always asked, "what is the difference between them" so we have sorted out some points about their differences as below:
