Explanation:
Digital rights management (DRM) is an access control technology used by hardware
manufacturers, publishers, copyright holders and individuals to impose limitations on the usage of
digital content and devices. It describes the technology that prevents the uses of digital content
that were not desired or foreseen by the content provider. DRM does not refer to other forms of
copy protection which can be circumvented without modifying the file or device, such as serial
numbers or keyfiles. It can also refer to restrictions associated with specific instances of digital

executables and scripts in order to confirm the software author, and guarantee that the code has
incorrect. A hypervisor is a virtualization technique that allows multiple operating systems (guests)
to run concurrently on a host computer. It is also called the virtual machine monitor (VMM). The
hypervisor provides a virtual operating platform to the guest operating systems and checks their
execution process. It provides isolation to the host’s resources. The hypervisor is installed on
resources from multiple administrative domains to achieve a common goal.
