Real-time applications are software applications that can process and deliver data in real-time or near-real-time, meaning with little to no delay. These applications are designed to provide instant feedback or results to users, which can include chat applications, gaming applications, stock market analysis tools, video and audio streaming platforms, and social media platforms. Real-time applications are typically built using technologies that support low latency and high throughput, such as WebSockets, Server-Sent Events, and long polling. They require efficient algorithms, low network latency, and high performance to ensure that they can process and deliver data in real-time, making them an essential tool for many businesses and industries, particularly those that rely on fast and reliable communication, analysis, and decision-making.
