Glossary
Key Terms, Defined Clearly
Plain-English definitions of terms across technology, AI, education, food science, and sustainability — written to be quick, accurate references.
Artificial Intelligence (AI)
Software designed to perform tasks that typically require human intelligence, such as recognizing patterns, making decisions, or generating language.
Example: A chatbot answering customer questions is a common real-world example of applied AI.
Machine Learning
A subset of AI in which systems improve at a task by learning patterns from data, rather than following explicit step-by-step instructions.
Example: Email spam filters that improve over time as they see more examples are a machine learning application.
Large Language Model (LLM)
An AI model trained on vast amounts of text data to understand and generate human language, used in tools like chatbots and writing assistants.
Example: GPT-style and Claude-style models are examples of large language models.
Small Language Model (SLM)
A more compact AI language model, typically faster and cheaper to run than a large language model, optimized for specific or narrower tasks.
Example: A customer-service chatbot trained only on a company’s product documentation may use a small language model.
Generative AI
AI systems capable of producing new content — text, images, audio, or code — rather than simply classifying or analyzing existing data.
Example: An AI tool that writes a draft blog post from a short prompt is an example of generative AI.
Prompt Engineering
The practice of crafting input instructions to get more accurate, useful, or relevant output from an AI language model.
Example: Adding specific formatting instructions to a chatbot query to get a structured table response is prompt engineering.
Answer Engine Optimization (AEO)
The practice of structuring web content so it is more likely to be surfaced directly in search engine answer boxes, featured snippets, or voice search results.
Example: Writing a direct 40-word answer at the top of an article is a common AEO technique.
Generative Engine Optimization (GEO)
The practice of structuring content so it is more likely to be cited as a source by generative AI tools like ChatGPT, Perplexity, or Gemini.
Example: Including clear, statistic-backed, quotable sentences in an article is a GEO technique.
Featured Snippet
A highlighted search result, typically shown above standard listings, that directly answers a user’s query using content pulled from a webpage.
Example: A recipe site whose ingredient list appears in a boxed summary at the top of Google results has earned a featured snippet.
Schema Markup
Structured data code added to a webpage that helps search engines understand its content, enabling rich results like star ratings or FAQ dropdowns.
Example: Adding FAQ schema to a page can make its questions appear as expandable items directly in search results.
E-E-A-T
A Google quality framework standing for Experience, Expertise, Authoritativeness, and Trustworthiness, used to evaluate content quality.
Example: An article written by a credentialed expert with a clear bio and sourced claims demonstrates strong E-E-A-T.
Evergreen Content
Content designed to remain accurate, relevant, and useful well beyond its publication date, unlike time-sensitive news coverage.
Example: A definitional glossary entry is evergreen content; a breaking-news bulletin is not.
EdTech
Technology designed specifically to support teaching and learning, including online course platforms, learning management systems, and educational apps.
Example: A platform that delivers interactive coding lessons to students is an example of EdTech.
Digital Literacy
The ability to find, evaluate, use, and create information using digital technologies, including assessing the credibility of online sources.
Example: Recognizing a fabricated news article by checking its source is an exercise in digital literacy.
Maillard Reaction
A chemical reaction between amino acids and reducing sugars that occurs when food is heated, producing browning and complex new flavors.
Example: The browned crust on a seared steak is a result of the Maillard reaction.
Fermentation
A metabolic process in which microorganisms like bacteria or yeast convert sugars into acids, gases, or alcohol, used to preserve and flavor food.
Example: Yogurt, sauerkraut, and sourdough bread are all products of fermentation.
Grid-Scale Battery Storage
Large battery systems designed to store electricity for the power grid, helping balance supply and demand, particularly with renewable energy sources.
Example: A warehouse-sized battery array that stores solar power for use after sunset is grid-scale storage.
Carbon-Neutral Cement
Cement manufactured using processes that significantly reduce or eliminate the carbon dioxide emissions typically associated with traditional cement production.
Example: A construction material startup using captured CO2 in its cement mix is pursuing carbon-neutral cement.
Four-Day Work Week
A work schedule model in which employees work four days instead of five, typically without a reduction in pay, often paired with restructured workflows.
Example: A company piloting a Monday-to-Thursday schedule at full pay is testing a four-day work week.
Digital Minimalism
An intentional approach to technology use that favors a small number of carefully chosen digital tools over constant, unstructured screen time.
Example: Scheduling two short windows per day to check email, instead of checking constantly, is a digital minimalism practice.
