Building a computer from scratch involves a hierarchy that begins with simple physical switches and ends with high-level software. This process—often referred to as "from bits and gates to C/C++"—is a fundamental journey in computer science that bridges the gap between electrical engineering and software development . The Computational Stack: From Sand to Software
To understand how a computer functions, you can view it as a hierarchy of abstraction, starting from physical electricity and ending with high-level software. This journey moves from to circuits , which form processors , all of which are controlled by code translated by compilers . 1.
