Answer / versha

jit is stands for just in time compiler
in case of compilation
source code ->language compiler->MSIL->JIT->native\machine

in case of compilation the source code is compiled by its
language compiler like in case of vb.net it is compiled by
its lanfuage comiler and then convert it in MSIL which jit
can understand and then jit compile itand convert it in
machine code

Answer / pankaj purohit

Agree with the Versha

But there are some different between Machine code and native

CLR will send it to OS

Different Machine code run in a sequences start form a to z
