The **** Runtime Environment (JRE) provides the libraries, the **** Virtual Machine, and other components to run applets and applications written in the **** programming language. In addition, two key deployment technologies are part of the JRE: **** Plug-in, which enables applets to run in popular browsers; and **** *** Start, which deploys standalone applications over a network. Users should install the 32-bit version if they are using 32-bit browsers. If you use both 32-bit and 64-bit browser interchangeably, you need a **** Plug-in for each browser. Hence you will need to install both 32-bit and 64-bit **** respectively.
