💻 Technology Vocab
Technology has added dozens of precise words to everyday English. We no longer just “use a program” - we open an interface, run an algorithm, or wait for lower latency. We sync devices, encrypt messages, and worry about privacy and bandwidth.
The fifty words below cover the core concepts, everyday actions, systems, and newer ideas that appear in modern digital life. Each entry includes a clear meaning, a realistic example, and a short nuance note.
⚙️ Core Concepts
🖥️ Interface
Meaning: The surface or connection that lets a person (or one system) talk to another system.
Example:
The new interface is cleaner, but some long-time users still prefer the older layout.
