In memory management, there are processes that need to be carried out to be able to use the storage efficiently and swapping is one of them. Swapping is the act of moving process between the primary and secondary memory so as to allow processes to work concurrently. It’s important to remember that swapping is temporary and that any process that has been swapped can be brought back in case it is needed for any execution.
Swapping is also known as memory compaction because it allows not just processes but big processes to run at the same time. The compaction process is made possible by the grouping of the empty memory spaces together and the process together to give an illusion of processes working in a parallel manner.
The time taken to swap a process is known to negatively affect the speed at which an operating system performs but the co-current process makes up for the lost time. When the idle and inactive process are temporarily moved to the secondary memory, the speed of the active process increase and improve the efficiency.
Here is how swapping results in better memory management
Higher processing speed
Since the active processes are given higher priority and the idle processes are swapped to the secondary memory the efficiency and speed will be on the higher side. This means that the tasks performed at certain periods will be executed with speed than when the processes are not swapped.
Better memory allocation
The transfer of process depending on the urgency allows the memory spaces to be used as efficiently and reduce wastage as in the case of paging. While the active processes are in the main memory being worked on the idle process and given a back seat on the secondary memory to ensure efficient memory allocation.
As stated before swapping allows a different process to run at the same time due to compaction of processes. Unlike other memory management techniques, swapping allows large programs to un at the same time without adversely affecting the speed at which the execution takes.
The ability to swap to allow the most important process to access the process from the secondary memory when it is needed by temporarily providing space on the RAM makes it the best technique especially when you want to prioritize some processes.
Some analysts believed that swapping wastes CPU time when it runs some processes in parallel. This is very far from the truth as the amount of time spent in executing a process is shortened due to the freeing of pace to the secondary memory from the main memory.
Dynamicrelocating is favored over static since dynamic relocation ensures that there is an efficient utilization of memory and dynamic will lead to wastage as some memory spaces will be left without processes. Dynamic relocation also allows the process to run at the same time without it affecting the way the process run individually.
For effective sapping, you should install DriverAssist to review and scan all the necessary drivers to ensure that they are working well.
