The article demystifies common AI terminology—LLM, Token, Context, Prompt, Tool, MCP, Agent, and Agent Skill—by explaining each concept, how they interrelate, and why understanding this chain clarifies the operation of modern AI products.
The article explains why the buzz around AI agents can mislead learners, breaks down overlapping concepts such as LLM, RAG, Tool Use, Agent, Code Agent, and Agent Platform into distinct layers, and outlines a step‑by‑step learning plan to build a solid conceptual map.
The article explores how machine learning models emulate human learning by converting diverse real‑world descriptions into numerical features, illustrating concepts such as one‑hot encoding, supervised, unsupervised, and reinforcement learning, and emphasizing the importance of mapping inputs to outputs for intelligent systems.
