In this post, we will understand the difference between contiguous and non-contiguous memory allocation −Contiguous Memory AllocationIn this allocation type, the consecutive blocks of memory is allocated to a file/process.It executes quickly in comparison to non-contiguous memory.It is easy to be controlled by the operating system.Minimum overhead since there are not many address translation when a process is being executed.There is internal fragmentation in contiguous memory allocation.There are different types of partitions: Single partition allocation and multi-partition allocation.Memory gets wasted.The swapped-in process is arranged in the originally allocated space itself.Non-contiguous Memory AllocationIn this type of allocation, separate blocks of memory ...

In this post, we will understand the difference between 3NF and BCNF.3NFThere shouldn’t be any transitive dependency.There shouldn’t be any non-prime attribute that depends transitively on a candidate key.It is not as strong as BCNF.It has high redundancy.The functional dependencies are already present in INF and 2NF.It is easy to achieve.It can be used to achieve lossless decomposition.BCNFFor any relation A->B, ‘A’ should be a super key of that specific relation.It is stronger than 3NF.The functional dependencies are present in 1NF, 2NF and 3NF.It has low redundancy in comparison to 3NF.The functional dependencies may or may not be preserved.It is ...
