As a memory pool is allocated from, over time the pool will become fragmented. Some objects from the pool will be allocated surrounded by objects that are not, in seemingly random order. Memory compaction is the process of moving allocated objects together, and leaving empty space together.
Consider a system with 3 pages and about 50% of their objects are allocated. By compacting all the living objects into the first two pages, leaving the third page completely empty. This empty page can then be ignored during future mark/sweep phases since it is known to be empty of living objects, or it can be released and returned to the operating system.

What is an example sentence for the word compaction?
The compaction of soil resulted in a more stable foundation for the building.
What is the process by which sediments get pressed together?
The process is called compaction and that is when the mineral grains are pressed together but have pore spaces in between and hot fluids can pass through. Cementation is when they are fully glued on and there aren't any pore spaces.
What is another word for burial compaction and cementation of sediment?
Diagenesis is the process that involves burial compaction and cementation of sediment.
What are some examples of compaction?
Examples of compaction include the process of soil being compressed by heavy machinery to create a solid foundation for construction, the compaction of trash in a landfill to reduce its volume, and the compression of snow into ice in a glacier.
What materials are good at compaction sand clay silt ect?
Sand is good for compaction due to its particle size and angular shape, helping to interlock and create stability. Clay is also good for compaction as it has small particles that can be easily molded and compacted. Silt is less ideal for compaction as it contains a mix of soil types and can be prone to settling and shifting.
When you perform compaction in memory management system?
When the memory resources are scarce. We use compaction.
What is meant by memory compaction?

What is the difference between segmentation and compaction?
Segmentation involves dividing memory into variable-sized partitions to allocate memory dynamically, while compaction rearranges memory to reduce fragmentation by moving allocated memory blocks closer together. Segmentation deals with memory allocation, while compaction improves memory utilization.
What is compaction in data structure?
The process of moving all marked nodes to one end of memory and all available memory to other end is called compaction. Algorithm which performs compaction is called compacting algorithm.
Which type of fragmentation is reduced by compaction?
External fragmentation is reduced by compaction. Compaction moves memory around until it is all placed together in one big block.
What is meant by compaction?
What is meant by the term 'compaction'
External fragmentation. Why is it needed?
External fragmentation describes the situation where free memory blocks are scattered throughout the memory space, which can make it challenging to find contiguous blocks of memory for larger programs or data. This can slow down the memory allocation process and waste memory resources. Techniques such as compaction or paging are used to reduce external fragmentation and ensure efficient memory utilization.
How does compaction work in Windows Vista?
