Crash Course Computer Science

Carrie Anne Philbin's CrashCourse series on how computers work from the bottom up. Episodes start with early and electronic computing, then cover Boolean logic and logic gates, binary representation, the ALU, registers and RAM, the CPU, instructions and programs, advanced CPU designs, early programming, programming languages, statements and functions, algorithms, data structures, and go on to operating systems, networks, the internet, cryptography and AI. It suits school students and non-CS learners who want the big picture. Follow with CS50x or VU CS101.
