Module 1: Foundations of AI · BoK I.A
Four building-block terms
Data, algorithm, model and system nest inside each other and the exam tests them exactly. An algorithm produces the model; the model applies algorithms to data; the system wraps everything including interfaces and infrastructure.
These nest inside each other. Definitions are short and the exam tests them exactly.
- Data - raw information used to train AI models → text, images, audio, video, sensor data
- Algorithm - a computational procedure, a set of instructions and rules, designed to perform a task, solve a problem or produce an AI model
- Model - a program that applies algorithms to data, letting it predict or decide based on learned patterns
- System - the full operational environment → data, algorithms, models, interfaces and infrastructure
Exam flash
Algorithm produces the model. Model applies algorithms to data. System wraps everything including interfaces and infrastructure. Mixing these up is the classic distractor.
