List one advantage and one disadvantage of having large block size.
Ans: Advantage: By using a huge block of memory is maximum process's accommodation that resulting is less no. of page faults.
Disadvantage: Use a large block of memory is internal fragmentation's incidence that is allocated memory may be slightly larger than requested memory. For example: assume that memory is assigned in blocks of 4K, single one 1K process will waste 3K of space into its partition that is a 5K process.
