I'm very new to Ubuntu, using 14.04. I need to make swap space, so I read, to overcome a garbage collector problem. My RAM is 8 GB, and my code is using big data and uses a lot of RAM.
What is swap space? Does it mean using flash memory or is it a way to use the RAM of the laptop? What should I do (from scratch)?
