Learning programming is essentially learning high-level languages, which are designed for humans to communicate with computers. However, computers do not understand high-level languages; they must be converted into binary code through a compiler to run. Knowing high-level languages does not equate to understanding the actual execution steps of a computer. The only language that computers … Read more
