<code><span lang="[phone]">'''Push technology,''' also known as '''server Push,''' refers to a communication method, where the communication is initiated by a [[Server (computing)|server]] rather than a client. This approach is different from the "[[Pull technology|pull]]" method where the communication is initiated by a client.<ref>{{Cite web |date=2012-11-18 |title=Push Technology |url=https://www.techopedia.com/definition/5732/push-technology |access-date=2023-07-23 |website=Techopedia |language=en-US}}</ref></span></code>

<code><span lang="[phone]">In push technology, clients can express their preferences for certain types of information or data, typically through a process known as the [[Publish–subscribe pattern|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.</span></code>

<code><span lang="[phone]">Under certain conditions, such as restrictive security policies that block incoming [[HTTP]] requests, push technology is sometimes simulated using a technique called [[Polling (computer science)|polling.]] In these cases, the client periodically checks with the server to see if new information is available, rather than receiving automatic updates.</span></code>
