Comparison of application virtualization software
open-in-new
<p>Application virtualization software refers to both application <a href="/facts/Virtual_machine/BLevU3sx">virtual machines</a> and software responsible for implementing them. Application virtual machines are typically used to allow application <a href="/facts/Bytecode/EPkMFR7M">bytecode</a> to run portably on many different computer architectures and operating systems. The application is usually run on the computer using an <a href="/facts/Interpreter_(computing)/JB85fbyb">interpreter</a> or <a href="/facts/Just-in-time_compilation/rEYDsd8l">just-in-time compilation</a> (JIT). There are often several implementations of a given virtual machine, each covering a different set of functions. </p>
