Virtual Box

VMWare has a free virtual machine player. That player is not a virtual machine. Optimum virtual PC that I use is Virtual Box from Sun Microsystems. It is under constant development and informs you in periods of time, quarterly or sooner, of updated versions with enhanced features and is backed by Sun Microsystems technology. If you go here you can have a look at different useful development tools and click on Sun Virtual Box and then be guided to its download area. We know that sun is the first developer of a virtual machine, Java Virtual Machine (JVM). Job of JVM is different from virtual boxes I am discussing. JVM takes a piece of code from an application smashes it into the bytes. In this way that application becomes independent of length of the word of host computer and becomes portable over the Internet into the different platforms. It remains for that host computer to have a small free JVM installed in a corner. In real experience it facilitates things drastically. That said. some believe that it is a matter of habit mostly than technology. You have a set of tools at the Sun's place, you can have a similar set all free from Microsoft Visual Studio Express edition and a similar set free from IBM and similarly from Oracle. And I'll discuss them later, hopefully.
