Question 1:                                                                                                                               Marks 10      Can we use DMA in protected mode or virtual mode of memory? Explain your answer with a solid reason. Solution:  The process for performing DMA transfers in the protected mode Windows environment should be similiar to the process for performing DMA transfers in the real mode MS-DOS environment. In both environments, […]
