Start before LLMs. Understand where AI, ML and neural networks fit.
Neural Network
A neural network is a mathematical pattern-learning system made of layers whose parameters are adjusted from examples.
Think of it like
Think of Neural Network as one layer in a very large toolbox: you only need to understand what job that layer performs.
Real life
A phone spam filter, recommendation engine, fraud detector or voice assistant may use Neural Network somewhere inside.
SRE lens
A language model is built from a large neural network rather than hand-written grammar rules.
