Mathematics to Abstract Machine Then Physical Computer

Computer Science and Engineering is a huge part of society. If we go through very minutely about where from Computer is coming. We can say Computer is an application of Mathematics. Firstly we have discussed K12 Mathematics at basic world accepted level then I had to do Mathematics at graduate level. There I have found digital computation. When I am discussing about Discrete Mathematics then it's along with Theory of Computation. Then Digital electrics has been designed in a simulation form. After that we have gone to physical design of Computer System that is nothing but Computer Architecture.
