I have ordered the book introductory CS course called The Elements of Computing Systems. . Hoping I can revist the ALU,CPU, .........assembler/vm/language/os .
Course simplifies Computer Science into a single course ( no need to study Computer Architecure , Assembly, language, complier, OS text books seperately ) ...one shot everthing in it . Don't know much about it ,but ordered the book. read below .TECS - The most amazing CS course I have seen!
