In JAVA, when source code(.txt file ) is compiled it turns
into byte code(.class file), actually this byte code is
something assembly instructions in JVM assembly and this
byte code is platform independent(as we can run our .class
code on any o/s, using specified JRE for that o/s.).
A byte code compiled by a compiler can run on any o/s like
windows, linux, unix, mac etc...
Machine code refers to a data that can be executed by a
specific computer having particular processor & o/s.(JRE
execute this data on specific o/s.)
JRE is provide by different o/s vendors.
