- Question
What is fragmentation? Different types of fragmentation?
- Correct Answer
- Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request External Fragmentation: External Fragmentation happens when a dynamic memory allocation algorithm allocates some memory and a small piece is left over that cannot be effectively used If too much external fragmentation occurs, the amount of usable memory is drastically reduced Total memory space exists to satisfy a request, but it is not contiguous Internal Fragmentation: Internal fragmentation is the space wasted inside of allocated memory blocks because of restriction on the allowed sizes of allocated blocks Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used

Correct Answer: Object Repository means not a collection of objects it's a common repository for all the people (testing, developers) for seeing all the data in single login for example QA wants to see 5 testers works then he goes to each person login and see the data It's very difficult job for this we can use Object Repository
