is this question answer correct there

(USERS WHICH POST SOLUTION AND COMMENTS ARE NOT ACTIVE SO POSTING HERE

I THINK EXTERNAL FRAGMENTATION SHOULD BE 0 AS EXTERNAL FRAG GENERALLY MEANS WE HAVE SPACE BUT WE CANT PUT PROCESS IN THAT SPACE DUE TO EITHER NOT CONTINOUS OR LESS SPACE . BUT HERE WE HAVE SPACE . SO I THINK IT SHOULD BE 0

Comments

as per my understanding, external fragmentation occurs in a variable partitioned memory systems, and that too when the requested memory size is there in the memory but not contiguous. had it be continuous, it would have been allocated to the process.

here as we're having the enough size of memory available, we can two blocks to the processes if the requested size is greater than the available size of blocks, to the processes. if we're not allowed to do the compaction, then what is the point of asking external fragmentation in the fixed partition scheme.

the point is i myself don't know the right answer. it's just what i've searched and didn't get any satisfiable answer, so i just made it up from my understanding. please let me know if you get answer from reliable source.

it occurs both in static and variable .so what about external fragmentation of above question what is it u think
