Q: – What is SWAP Space?
Swap space in Linux is used when the amount of physical memory (RAM) is full. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space. While swap space can help machines with a small amount of RAM, it should not be considered a replacement for more RAM. Swap space is located on hard drives, which have a slower access time than physical memory.
– Create swap partition or file
– Write special signature using “mkswap”
– Activate swap space by “swapon –a” command
– Add swap entry into /etc/fstab file
