What is the practical significance of fork

[Chaitannya Mahatme]

Hello Everyone, I tried finding answer to this question in many books but never quite got a satisfactory answer to this question. A fork process would replicate it parent, my question is Why is fork necessary to create a process. Why replicate a existing process before creating a new process. The exec algorithm is executed after fork which overrides what fork has done, then why do fork. Why can't we directly do exec. -- Cheers !!!
