Manual Refresh: Some websites and platforms might require users to manually refresh their browser page to see new messages. This is less common in modern web applications due to advancements in real-time data updates. Manual refresh was more common in the early days of the internet and web design.
Automatic Updates: Most modern social media platforms and messaging apps use technologies that allow messages to appear automatically without the need for the user to refresh the page. Technologies like WebSockets, Server-Sent Events (SSE), and AJAX (Asynchronous JavaScript and XML) polling are behind these real-time updates. They keep a live connection open between the server and the user's device, pushing updates to the client as soon as they happen.
Notifications (Buzzing): In addition to showing messages automatically within the app or website, many platforms also send notifications to the user's device. These can be in the form of sound alerts, vibration (buzzing), or visual notifications. For mobile devices, these notifications require the user to allow the app the necessary permissions to send alerts. On desktops or laptops, web browsers can also deliver notifications with user permission. Notifications are designed to alert the user of new messages even when they're not actively looking at the app or website.
