External fragmentation is the phenomenon in which free storage becomes divided into many small pieces over time.[1] It is a weakness of certain storage allocation algorithms, occurring when an application allocates and deallocates ("frees") regions of storage of varying sizes, and the allocation algorithm responds by leaving the allocated and deallocated regions interspersed.

Compare Contiguous memory allocation with internal fragmentation?

in early, computer system has contiguous memory allocation,each process is allocated in a single contiguous(together) memory!!(allocating into memory addresses one by one,)it has tackled memory fragmentation(both internal and external). not allocating for a fixed size memory block.so no internal fragmentation, allocating contiguously ,so no external fragmentation!!!

Why is the internal resistance of a voltage source made to be low?

When a voltage source, such as a battery or a generator, is on open circuit -in other words, when it is not supplying a load- the voltage appearing across its terminals is called its 'open circuit voltage' and corresponds numerically to its electromotive force.However, when the voltage source supplies current to a load, that current also passes through the voltage source itself. This causes an internal voltage drop, which is the product of this current and the voltage source's internal resistance. This voltage drop acts in the opposite direction to the electromotive force and reduces the source's terminal voltage. This internal voltage drop will increase, of course, if either the load current increases or the internal resistance increases.So, in order to keep that the source's internal voltage drop is as low as possible, its internal resistance must be as low as possible. In the case of a battery, the internal resistance is due to the ionic resistance of the electrolyte/plates, whereas in a generator it is due to the resistance of the windings.

Does paging suffer from internal fragmentation?

If there are large blank spaces in each page of the program then internal fragmentation can occur. Smaller pages can remedy this, but the overall amount of pages will then increase, causing slowed execution.

Definition of internal fragmentation and external fragmentation?

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 is the difference between external fragmentation and internal fragmentation in memory management?

External fragmentation occurs when free memory blocks are scattered throughout memory, making it difficult to allocate contiguous blocks of memory to processes. Internal fragmentation, on the other hand, happens when allocated memory is larger than what is actually needed, leading to wasted space within memory blocks.


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.

What is the difference between internal and external fragmentation in OS?

Internal Fragmentation is the area in a region or a page that is not used by the job occupying that region or page. This space is unavailable for use by the system until that job is finished and the page or region is released.
