Actually I wanted to know complete flow. How hardware works. What all are the process carried it to work.

Machine code ( http://en.wikipedia.org/wiki/Machine_code ) is just a bunch of bit patterns that are hardware specific. So one one cpu if you load 010101 into some register (memory unit) it does one thing, and on another cpu it may do something else depending on the hardware. cpus tend to have such basic operations such as the logical operators (or, and, xor, not) and mathematical operations (addition, subtraction) and so forth! one register could contain a number (in binary of course), then another register could contain a 2nd number, then a certain bit pattern could tell the cpu to add the two registers and store the output somewhere. writing assembly code can be very time consuming when implementing more complex software design patterns or larger applications. These abstractions are easier implemented in C code. C code is translated to assembly when you compile your code (so you could audit it or something) and then converted to machine code which is what a binary (exe in windows) is made up of.
