Change Swappiness

I installed CentOS on VirtualBox on my work laptop which has very poor specs. I gave it 512 MB RAM and a single core. Within about 20 minutes the VM started swapping and the whole laptop became extremely slow. I had been researching the problem and came across "swappiness".

I have changed this setting to zero (0) on this VM. I will test and report back.

What is swappiness and how to change it?
