OpcodeAtlas

Opcode Atlas makes animated explainers about how software and computers actually work, one journey at a time.

Every episode picks something you do every day, like pressing a key, loading a web page, or running a search, and follows it through the machine stop by stop: hardware, firmware, operating system, networking, and the code that ties them together. Clear diagrams, real bytes, and no hand-waving.

Topics include computer science fundamentals, operating systems, CPUs and memory, USB and hardware interfaces, networking and the internet, databases and search engines, compilers, and how programs run. It's built for curious developers, CS students, self-taught programmers, and anyone who has wondered what really happens under the hood.

Sources for every episode are linked in the description.
