Curcumin is the yellow pigment associated with the curry spice, Turmeric, and to a lesser extent Ginger. It is a small molecule that is the prototypical 'curcuminoid', and has effects similar to other polyphenols but unique in a way as it is a different class of polyphenol (relative to the other classes of 'flavonoid', 'stilbene', etc.)
The most simple definition of virtualization is the creating of a virtual version of something. This could be an operating system, server, storage device, or other resources. One common example would be someone who has divided their hard drive into multiple partitions. Uses.
A virtual machine is nothing but a data file on a physical computer that can be moved and copied to another computer, just like a normal data file. The computers in the virtual environment use two types of file structures: one defining the hardware and the other defining the hard drive. The virtualization software, or the hypervisor, offers caching technology that can be used to cache changes to the virtual hardware or the virtual hard disk for writing at a later time. This technology enables a user to discard the changes done to the operating system, allowing it to boot from a known state.
