Configure SWAP Memory on Ubuntu With AttuneOps
This Blueprint Configures SWAP Memory on Ubuntu With AttuneOps
Swap memory or swap space is the on-disk component of the virtual memory system. Memory swapping is a computer technology that enables an operating system to provide more memory to a running application or process that is available in physical random access memory (RAM). In short, swap memory is the dedicated amount of hard drive that is used whenever RAM runs out of memory.
