Swap Space in Linux / RHEL / CENTOS / Fedora



What is a Swap space?
  • Swap space is hard disk space that extends system RAM.
Swap space or virtual memory is hard disk space that acts as an extension of system RAM. Of course, due to the relative differential in data access on RAM versus hard disk, we prefer not to use swap space if it can be avoided. Nonetheless, it is vital to the proper functioning of a typical Linux system that some swap space be made available.
