In this case,

Processor : now if we consider size of ALU (16 bit or 32
bit) then int size get differed.

OS: in case of OS size of int varies in windows & linux.

Compiler : In case of compiler, C compiler has size of int 2
bytes while on same OS & processor Java compiler has 4 bytes

Finally conclusion is as per operation capacity of ALU,
operating systems are designed.

while in case of compiler i think they work in somewhat
upper layers so it doesn't matter with internal operation.
