Whats the mechanic of a processor how does it work ?

Thanks for asking!

I've selected three primary resources which explain the mechanics of
processors. The sources are listed in order of complexity, from
simplest (Intel), to more detailed (How Stuff Works) to fairly
technical (PC Guide).


Intel Education ----------------------------------------------------------------------

Intel's Guide to Microprocessors provides a step-by-step illustrated
explanation of a simple arithmetic processor operation.

"A microprocessor executes a collection of machine instructions that
tell the processor what to do. Based on the instructions, a
microprocessor does three basic things:

-- Using its ALU (Arithmetic/Logic Unit), a microprocessor can 
   perform mathematical operations like addition, subtraction,
   multiplication and division. Modern microprocessors contain 
   complete floating point processors that can perform extremely 
   sophisticated operations on large floating point numbers. 

-- A microprocessor can move data from one memory location to 
   another. 

-- A microprocessor can make decisions and jump to a new set of 
   instructions based on those decisions."
