Difference Between 16bit and 32bit OS
hi all,
can anybody tell me the difference between 16bit Operating System and 32Bit operating system.
what i know is that in 16bit os the sizeof int is 2 bytes and in 32bit os sizeof int is 4 bytes.
In one of the interviews i came across one question that write an algoritm to know wheather your Os is of 16bit or 32bit
so what will be correct answer. just checking sizeof(int) ????
is there any other difference between 16bit os and 32bit os....
one more question is . what is the difference between DLLs developed in 16BIT os and 32bit OS.....
Thanks in advance

Difference Between 16bit and 32bit OS
to add to the confusion i have heard that the size of int is shown differently in different compilers on the same op system.that means it somehow depends on compilers as well.Sudhir Kesharwani <sudhir.kesharwani@...> wrote:

Hi Sudhir,
The main difference between 16 bit and 32 bit OS is
that a 16 bit OS supports processors having 16 bit
data bus and 32 bit OS supports processors having 32
bit data bus.
The data bus size specifies the word size of the
processor which describes how much bytes the processor
can read in a single Memory read cycle ( though there
are constraints on byte alignment).
For example, a through a 32 bit processor, you can
read 4 bytes of data in a single memory read
instruction.

Pretty sure about it. Run TC on Win32 to print the size of `int`. I bet
that you get 16 instead of 32, since it is a 16-bit application despite
running on 32-bit OS.
OTOH, 8-bit embedded C compilers might use 16-bit integer. So I doubt that
checking the size of `int` might give any useful conclusion.
