In essence, pre-training is a principle used to prevent someone who’s learning a new concept from getting overwhelmed by a large amount of new information. Its main feature is to enforce key concepts of a more complex topic to a novice, or someone just getting started in the topic. It helps to reduce the time it takes for someone to learn something and makes it so they can understand and retain it better. I plan to do this in my portfolio by doing a journal/video blog, or a few about cybersecurity related topics and summarizing it for someone who might not be as knowledgeable about it.
