Black and Wiliam (1998a) also noted that for assessment to function formatively, the feedback information had to be used, and thus the differential treatments that are incorporated in response to the feedback are at the heart of effective learning.
A hypervisor is a unique type of software that allows a computer to run more than one operating system (OS). Through a process known as virtualization, the software tricks each OS into thinking it has exclusive access to a particular set of hardware.
When an administrator designates a network adapter for use with Hyper-V, the hypervisor creates a virtual switch and then binds it to a physical network adapter. All of that adapter's communications pass through the virtual switch. All communications from the host operating system pass through the virtual switch. The physical network adapter is exposed through the host operating system just as it would have been prior to the creation of the virtual switch. However, Hyper-V changes the network adapter's configuration.
