Today’s WhatIs.com Word of the Day is hardware emulation, the use of one hardware device to mimic the function of another hardware device. An administrator must use hardware emulation if he needs to run an unsupported operating system (OS) within a virtual machine (VM). In such a scenario, the virtual machine does not have direct access to server hardware. Instead, an emulation layer directs traffic between physical and virtual hardware. Continued…
