Swapping:
Swapping is the process of moving a suspended process from memory to disk to free up space in the main memory for other processes. When a process is suspended, it is temporarily removed from the main memory and stored on the disk until it is ready to resume execution. This allows the operating system to manage the limited memory resources efficiently.

Reason for Swapping:
- One of the main reasons for swapping is to prevent the main memory (RAM) from becoming full and causing the system to slow down or crash.
- Swapping helps in optimizing the overall performance of the system by allowing more processes to be executed concurrently without running out of memory.

Steps in Swapping:
- When a process is suspended, the operating system identifies a suitable location on the disk to store the process.
- The contents of the process, including its code, data, and stack, are transferred from the main memory to the disk.
- The operating system keeps track of the location of the process on the disk so that it can be easily retrieved when needed.

Benefits of Swapping:
- Swapping helps in increasing the overall system performance by efficiently managing memory resources.
- It allows the system to run more processes simultaneously without running out of memory.
- Swapping helps in preventing memory-related issues such as system crashes and slowdowns.
In conclusion, swapping plays a crucial role in the efficient management of memory resources in a computer system by temporarily moving suspended processes from memory to disk and then retrieving them when needed.
