How Computer Works ?

Here we will discuss about step by step procedure of how computer works ?

Step 1 : Firstly, Computer Takes Raw Data as Input From USER through input device.

Important Point To Remember : Computer Takes Input From User Written in High Level Language(HLL).

Step 2 : Store Input Data Into Memory.

Step 3 : Convert Input data into computer understandable language called Machine Level Language (MLL) / Low Level Language.

Important Point : Computer Understand Low Level Language / Machine Level Language.

Step 4 : Perform desired operation on input data given by user.

Step 5 : Produce Output on output device.
