Synchronous vs Asynchronous
Contrasting immediate thread-blocking operations (Request-Response model) against decoupled, event-triggered background routines — covers polling patterns, server-sent events, and long-lived connections.
What you'll learn
- Synchronous (Blocking)
- Asynchronous (Non-Blocking)
TL;DR

Concept Overview
Synchronous vs. Asynchronous Calls determines how execution threads interact over a network. Synchronous calls block execution until a response is received, while Asynchronous calls fire requests and continue execution immediately, handling returns later.
Key Architectural Pillars
Synchronous (Blocking)
Sender makes request and halts local process thread execution waiting for receiver response.
Asynchronous (Non-Blocking)
Sender fires request, continues execution immediately, and receives responses via callbacks or event queues.
