Glossary
Plain-English definitions of technical terms that business owners encounter when evaluating, buying, or managing software projects.
What Is Hashing
Definition Hashing is a process that takes a piece of data — a password, a file, a message — and converts it into a fixed-length string of characters called a hash. Unlike encryption, hashing is a one-way process. You cannot take the hash and reverse it to get the original data back. The same input always produces the same hash,...
What Is Horizontal Scaling
Definition Horizontal scaling is the approach of handling increased demand by adding more servers to your infrastructure rather than upgrading the hardware of a single server. Instead of making one machine more powerful (which is vertical scaling), you distribute the workload across multiple machines that work together. A load balancer sits in front of them, directing each incoming request to...
What Is HTTPS
Definition HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP, the protocol your browser uses to communicate with websites. The “S” stands for Secure, and it means that all data exchanged between the visitor’s browser and the web server is encrypted using TLS (Transport Layer Security). This encryption prevents anyone from intercepting, reading, or tampering with the data...
What Is Human Handoff
Definition Human handoff is the process of transferring an interaction from an automated system — typically a chatbot or AI agent — to a human team member when the situation exceeds the system’s capability or confidence. A well-designed handoff passes the full context of the conversation to the human, so the customer or user does not have to repeat themselves....
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.
