Summary

These are several of the more encompassing sources I came across recently on the basics of working with bits and bytes, especially in C++. More directy memory management and bit manipulation is not something I come across often using C# in Unity, but it still seems good to understand as it does come up every now and then. Unity uses bit maps for instance with their layer masks, which reading these sources greatly helped me understand better. I am also starting to do more work in Unreal, which uses C++ as its primary language, where I feel like this type of work is done more often.
