# exchange (0-exchange.com)

People say exchange to mean swapping one thing for another. They might trade money for foreign currency, return a gift at a store, or trade ideas with a colleague. It is about giving and receiving in return.

## What a model may hear
- email server (Microsoft enterprise software): assume the user wants to configure mailboxes, calendars, or Active Directory integration
- cryptocurrency trading platform (finance and blockchain technology): fetch market data, execute trades, or manage wallets and order books
- message broker or queue (distributed systems and cloud architecture): route messages between services using protocols like AMQP or MQTT
- ion exchange or chemical process (chemistry and water treatment): describe resin-based purification or molecular swapping in solutions
- stock exchange (financial markets): reference specific market hours, ticker symbols, or regulatory frameworks

## Where people and models part ways
- Says: "Set up an exchange for my team"
  Means: Create a shared space for team members to share files and ideas
  May be taken as: Deploy Microsoft Exchange Server or configure an email domain
  Say instead: "Create a shared folder or team workspace where we can exchange files and messages"
- Says: "I need to make an exchange today"
  Means: Trade dollars for euros before a trip
  May be taken as: Execute a cryptocurrency trade or stock market order
  Say instead: "Convert dollars to euros at a currency exchange"
- Says: "Build an exchange between the services"
  Means: Let two applications share data back and forth
  May be taken as: Implement a message broker like RabbitMQ or Kafka with specific routing logic
  Say instead: "Let the two applications send data directly to each other through a simple shared endpoint"

## Tips
- Say currency exchange, stock exchange, or data exchange to narrow the meaning
- Mention the brand if you mean email, like Microsoft Exchange
- Say swap or trade instead of exchange when you mean a simple one-for-one replacement
- Add peer-to-peer or centralized if you mean how parties connect
- Specify the items being exchanged, not just the act, to avoid broker assumptions

## Often confused with
- swap: more casual, rarely means a financial platform
- trade: broader, includes barter and one-way transactions
- transfer: one-way movement, no reciprocity expected
- marketplace: a venue for many buyers and sellers, not the act of swapping
- broker: an intermediary, not the platform or act itself
- convert: one thing becomes another, no two-party give-and-take
