Push technology^[2] is a communication method used mainly in web-based applications. It involves a server sending information to the client without a specific request from the client, providing real-time updates. This technology is widely used in various applications such as instant messaging^[1], email^[3] systems, online auctions, and sports results among others. Examples of push technology include Web push proposal, Web Notifications API^[4], Push API, HTTP server push, and Web Socket API, which are all implemented in most browsers for data delivery and communication. Mechanisms used for HTTP server push include chunked transfer encoding, multipart/x-mixed-replace MIME type, Server-Sent Events, and HTTP streaming. The technology also utilizes methods like pushlets and long polling techniques for continuous data updates. In cloud computing, it supports Reliable Group Data Delivery (RGDD) by replicating data across multiple machines for reliability. This summary provides a simplified understanding of push technology and its various applications.

Terms definitions

1. ↑ instant messaging. Instant Messaging (IM) is a digital communication method that enables real-time transmission of text-based messages over internet or computer networks. Unlike email, IM facilitates immediate, interactive conversation, often enhanced with emojis, file transfers, voice-over IP, and video chat. IM systems can function independently or as part of a larger social media platform. They have evolved significantly since early systems like Talkomatic and CompuServe CB Simulator, developing into graphical user interfaces with a wide range of features. Today's popular services, including Signal, Telegram, WhatsApp, and Snapchat, offer private and group messaging, advanced security measures such as end-to-end encryption, and integration with social networks. They play a vital role in both personal communication and business environments, facilitating effective real-time communication with conversation records for future reference.

2. ↑ technology. Technology, derived from the Greek words meaning craft and knowledge, is a broad term that refers to the tools, machines, and systems developed by humans to solve problems or fulfill objectives. Originating with primitive tools like stone axes and the discovery of fire, technology has evolved significantly throughout human history. It has been instrumental in different eras, from the invention of the wheel and advanced irrigation systems in ancient civilizations to the birth of universities and printing press during the medieval and Renaissance periods. The Industrial Revolution in the 18th century marked a significant shift in mass production and innovation, giving rise to modern technologies like electricity, automobiles, and digital communication platforms. Today, technology is integral to various aspects of life and society, driving economic growth and societal change, while also raising concerns about security, privacy, and environmental impacts. The future of technology is expected to bring even more advancements, with the rise of artificial intelligence predicted to have significant implications for the job market.

Push technology, also known as server push, refers to a communication method, where the communication is initiated by a server rather than a client. This approach is different from the "pull" method where the communication is initiated by a client.

In push technology, clients can express their preferences for certain types of information or data, typically through a process known as the publish–subscribe model. In this model, a client "subscribes" to specific information channels hosted by a server. When new content becomes available on these channels, the server automatically sends, or "pushes," this information to the subscribed client.

Under certain conditions, such as restrictive security policies that block incoming HTTP requests, push technology is sometimes simulated using a technique called polling. In these cases, the client periodically checks with the server to see if new information is available, rather than receiving automatic updates.
