What type of fragmentation is caused by relocatable dynamic?

Relocatable dynamic fragmentation is caused by the repeated allocation and deallocation of memory blocks of varying sizes, leading to small gaps that may not be reused efficiently due to mismatches in size requirements. Over time, this can result in a high level of fragmentation and a decrease in memory utilization efficiency.


Difference between internal fragmentation and external fragmentation in operating system?

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

What are the criteria for effective strategy?

The three tests for an effective strategy are: external, internal, and dynamic consistency.


How external fragmentation can be remove in contigous memory allcation?

External fragmentation in contiguous memory allocation can be reduced by implementing compaction, which involves shifting allocated memory blocks to consolidate free space into a single large block. Another technique is to use dynamic partitioning with variable-sized memory blocks to minimize wasted space between memory allocations and deallocations. Using memory allocation strategies like first fit, best fit, or buddy system can also help in reducing external fragmentation.

This space is unavailable for use by the system until that job is finished and the page or region is released.


Difference between fixed partition and dynamic partition in memory management?

Fixed partitions have fixed size and usually cannot be easily expended or shrunk. Dynamic partitions can change size by themselves when they need it. There are some advantages of using fixed partitions because you control its size. It might happen that you can run out of free space when you are using dynamic partitions.


What is an example of dynamic?

An external force that moves or changes


What describes an object in dynamic equilibrium?

An object in dynamic equilibrium has equal and opposite forces acting on it, resulting in no net acceleration. This means the object is either at rest or moving at a constant velocity. In this state, the object's internal and external forces are balanced, allowing it to remain in equilibrium.


What is a character with an internal conflict?

create a dynamic character.


How is both external and internal stimuli involed in you actions?

Both external and internal stimuli significantly influence my actions. External stimuli, such as environmental cues or social interactions, prompt responses based on immediate context, like reacting to a loud noise or engaging in conversation. Internal stimuli, including thoughts, feelings, and physiological states, shape my decisions and motivations, guiding me based on personal experiences and emotions. Together, these stimuli create a dynamic interplay that drives my behavior and responses in various situations.
