(But remember it is not equal to always frame number, there might be some more bits such as reference bit, dirty page bit, etc present, but don't worry about that here, that would explicitly mentioned in the question) So, PTE = frame number no of frames = MM size/PS = 264 /216 = hence total frames = 2^48 (bits req =48= frame number = PTE) 1 votes 1 votes Pawan Kumar 2 commented Dec 29, 2017 reply Follow Share got it sir thank you everyone 1 votes 1 votes Please log in or register to add a comment.
