Live Data vs. Traditional HTTP
Compare and contrast live data communication patterns with traditional request-response HTTP models and understand their respective benefits.
Welcome to Live Data!
What is "live data"? Think about apps that update instantly, like stock prices or sports scores. This lesson explores how that magic happens and why it's different from regular web browsing.
We'll compare it to the traditional way the internet works: HTTP.
HTTP: Ask and Get
The internet mostly runs on HTTP (Hypertext Transfer Protocol). It's like asking a librarian for a book:
- You (the client) send a request to a server.
- The server finds the info and sends back a response.
- Each request is separate; the server "forgets" about you until your next request.
