Push System
A push system is a communication model where a server or sender proactively sends data to clients or receivers without waiting for explicit requests. It enables real-time updates and notifications, such as in chat applications, live sports scores, or stock market feeds. This contrasts with pull systems, where clients must periodically poll the server to check for new data.
Developers should learn push systems when building applications requiring instant data delivery, low latency, and efficient resource usage, such as in collaborative tools, IoT monitoring, or social media feeds. It reduces unnecessary network traffic by eliminating constant polling, making it ideal for scenarios where timely information is critical, like emergency alerts or live broadcasting.
