The main difference between an compiler and an interpreter
is that a compiler executes the program entirely at a time
and that of a interpreter is that it goes on line by line
storing each lines output separately i.e interpreter
executes only when there is a need for the execution. the
best example of a software product is that acts as an
interpreter is a JVM which is nothing but a interpreter. lot
of them say that java is a language but there as as many
proofs that argue that java is a package to those who say it
a language.

* one more diff. is that the time of execution of a compiler
is very high when compared to an interpreter .........
