A virtual machine is an environment where a piece of code can run. In other words the virtual machine translates your code into system calls. While assembler and C compilers compile the human- readable code directly into bit code (the code the computers can understand) you don't need a "translator" but the higer level programming language compilers compile the code into byte code (bit = 0 or 1 and byte = 8bits) and they need a virtual machine or translator in order to function. The most used virtual machine currently used is Sun's Java Runtime Environment or JRE downloadable from Sun's site but I don't think you can debug their JRE. You can debug your own java code though.
