Websites accept results either through manual operator input or automated processes like cron jobs which push updates at scheduled times.
On update, the new value is stored in the database, a JSON endpoint is updated, and front-end scripts fetch the latest value to update the UI without a full page reload.
Auto-refresh mechanisms such as AJAX polling or WebSockets keep the user interface synced with backend changes while keeping bandwidth low.
What is a cron job?
A scheduled task on the server that can push updates at set times.
Why use JSON endpoints?
They allow lightweight data transfer and fast front-end updates.
Can front-end polling be omitted?
It can; alternatives include WebSockets or Server-Sent Events for real-time push.
