Answering Basic Assembly Language Questions - Assembly Language for Beginners Creel 2022-07-28 | In this video we answer several basic questions regarding x86/64 Assembly Language programming. The language has a steep learning curve, but once the fundamentals are understood, the whole journey becomes an exploration of the capabilities of a modern CPU. I have tried to keep things fairly simple, but even the basics in Assembly can be fiddly and difficult without clear step-by-step explanations of what is happening in the CPU.
