But how best fit is free from internal fragmentation . In best fit allocation small holes will be created due to allocation . So as per my knowledge both internal and external fragmentation will occour . And solution is Compaction. Correct me if I'm wrong . 2 votes 2 votes SHUBHAM SHASTRI commented Sep 9, 2018 reply Follow Share yes you are correct @Amit pal ...both internal and external Fragmentation are there ... 0 votes 0 votes arvin commented Sep 9, 2018 reply Follow Share yes you are right it will be compaction i did silly.both of the best and worst fit will suffer from both internal and external fragmentation but the only thing we can remove here is external fragmentation with compaction (though its costly). and you cannot remove internal fragmentation with linking or compaction and it can be only done with design change. so option D is best here. 1 votes 1 votes Please log in or register to add a comment.
