*Logical address is address generated by CPU during execution* whereas Physical Address refers to location in memory unit(the one that is loaded into memory).Note that user deals with only logical address(Virtual address). The logical address undergoes translation by the MMU or address translation unit in particular. source: Geeksforgeeks

13:30 . I have a doubt, In the numerical the P0 process PA(Physical Add.) starts at 1200 and has limit of 500 therefore the PA should end at 1700. But then the Process P3 is starting at 1400. Is it possible? (Overlapping of Addresses).

[@kirtitripathi563]

It's only a example to understand the concept....for a program/ process base address will same......

4:40 Sir aapne kha ki logical address me instruction no. Hai and hm usme base address add karke main memory me usse search krte hai But agr logical address me sirf program ka instruction no. Hai to vo usse secondary memory me kaise search krte hai Kyuki secondary memory me to bohot saare programs hai. Khali program ke instruction no. Se kaise milega program. Secondary memory ke liye koi base address nhi chahiye kya!?? Kyuki cpu ko to pta hi nhi ki bich me main memory hai to vo to khali logical address se hi search krne wala tha s.m. me wha bhi to use base address chahiye hoga So my question is kya secondary memory me bhi base address jaisa kuchh hota hai. Please clear my doubt sir

[@shreyshreyansh]
