Linux- Swap Space

🔰 Managing Swap Space

Imagine your system has only 2GB of RAM, but an application requires 3GB. Without swap space, this process would fail or crash because there isn’t enough memory available. With swap, however, the OS can shift inactive data into this overflow area, making room for the application.

In this way, swap acts as a safety net, allowing the system to handle memory-heavy tasks smoothly even when RAM is limited.

While swap space isn't as fast as physical RAM, it can be a lifesaver in those situations.
