Plain-English definitions of technical terms that business owners encounter when evaluating, buying, or managing software projects.
What Is Nginx
Definition Nginx (pronounced “engine-x”) is a web server — the software that receives requests from browsers and delivers your website’s pages in response. It was designed from the ground up to handle a very large number of simultaneous connections efficiently, which makes it particularly well suited to busy websites. Beyond serving web pages, Nginx is commonly used as a reverse...
What Is NLP
Definition Natural language processing (NLP) is a branch of artificial intelligence focused on enabling computers to understand, interpret, and generate human language. It covers a broad range of capabilities: reading and classifying text, extracting specific information from documents, detecting sentiment, translating between languages, summarising long passages, and generating new text. NLP is the underlying technology that makes voice assistants, chatbots,...
What Is Node.js
Definition Node.js is a runtime environment that allows JavaScript — a language traditionally confined to web browsers — to run on servers. Before Node.js, if you wanted to build a website’s backend (the part that handles databases, authentication, and business logic), you had to use a different language from the one running in the browser. Node.js removed that barrier. It...
What Is NoSQL
Definition NoSQL (which stands for “Not Only SQL”) is a category of database systems that store data in formats other than the traditional rows-and-columns table structure. While relational databases like MySQL and PostgreSQL require you to define a rigid schema before storing data, NoSQL databases are more flexible. They come in several varieties: document databases store data as JSON-like documents,...
About the Glossary
Why Plain Language Matters More Than Technical Fluency
Every software project involves terminology that business owners are expected to understand but rarely have reason to learn. Developers use terms like API, CI/CD, middleware, and bearer token as if everyone shares the same vocabulary — and when a client nods along without fully understanding, decisions get made on incomplete information. That gap between technical language and business understanding is where the most expensive mistakes happen: approving architectures you cannot evaluate, signing off on testing strategies you cannot verify, and accepting timelines based on concepts you have not had properly explained.
This glossary exists to close that gap. Each entry provides a plain-English definition, an explanation of why the term matters to your business, and a concrete example of the concept in action. These are not textbook definitions written for computer science students. They are practical explanations for the person who needs to make decisions about software without becoming a developer in the process.
We built this glossary from the questions our clients actually ask — in discovery calls, during project reviews, and in Slack threads where someone finally admits they are not sure what a term means. The entries reflect what business owners genuinely need to understand, not what a technical writer thinks is important. Across hundreds of client engagements, we have found that the single biggest predictor of a smooth project is a client who understands enough vocabulary to ask the right questions. Not to write the code — just to evaluate the answers they are given.
The definitions here deliberately link to deeper content elsewhere on the site. If a glossary entry sparks a question about how we implement something, the Knowledge Center, Services, and Systems sections have the full picture. The glossary is the starting point, not the destination.
