Dictionary

This is a running glossary — not a computer science course. Use it when a conversation, ticket, or AI answer throws jargon at you.

How it’s organized

• Talking with developers & AI — tickets, repos, roles, how work gets described
• Web, backend & deployment — browsers, servers, APIs, hosting
• AI & models — prompts, agents, tokens, and product words

Terms overlap in real life; pick the file that matches how you’re stuck. When you’re ready to ship something, use Build an app; for free tools and chat, see Free resources and Free chat AIs.
