Discuss the association between PVM and byte code.
Answers
JVM (Java Virtual Machine) has a direct set of machine type. The name provided by this instruction set is Java bytecode. This is described in the Java Virtual Machine specification. Other languages are translated into a bytecode before executing, for example Ruby and Python. Java's bytecode is at a very low level, but Python is high.
Interpretation and JIT compilation are two different strategies to implement the biotechcode. Through lectures process, bytecodes alter the virtual machine state at the same time that are encoded in every direction. JIT compilation translates bytecodes according to the original instructions of the host platform, which performs equivalent operations.
In the PVM, particular set of codes mean different things so Not all CPU's use the same set and major difference is between CISC and RISC.
Same code might not be used in another CPU so major reason you need to recompile for other machines.
Many reasons includes OS might require other means of communicating with or Windows / Linux in same CPU do not work with the exact same binary executable.
