Under the best possible circumstances (where an adversary gets to choose which 512K is occupied), what is the largest possible size process that can still fit in memory? Explain your answer

Solution

2^nd if it is out off order it would be depend on the size of the requested memory and located to the enough biggest list with round off size.

Under the best possible circumstances the biggest memory size would be 512k for first condition that is free after allocation of 512k from the 1M (1024k) and for the second condition whatever the sequential byte of free memory is available.
