why does when module is compiled other than .ko many other files gets created?

["Manjunath Naik" <peter.desouzain@xxxxxxxxx>]

  Hi all,

    finally I was able to simple  module on my machine with latest
kernel. But when I compiled the modules which is named simple.c with
make file following files are created.

      1. simple.o
      2.  simple.ko
      3. simple-lkm.mod.c
      4. simple-lkm.mod.o

   I was expecting only the simple.ko file. What is the significance
of other files.

Thanks
Manjunath Naik
