Option 4 : Push Technology
The data that is pushed from a server to a client without client requests is called Push technology.
- The technical word used to describe a server sending a message to the client without a client initiating a request to a server asking for a specific payload is commonly referred to as Push Request.
- It is contrasted with pull/get request, where the request for the transmission of information is initiated by the receiver or client.
- Push services are often based on information preferences expressed in advance. This is called a publish/subscribe model.
- A client "subscribes" to various information "channels" provided by a server; whenever new content is available on one of those channels, the server pushes that information out to the client.
- Synchronous conferencing and instant messaging are typical examples of push services. Chat messages and sometimes files are pushed to the user as soon as they are received by the messaging service.
- Pull technology refers to clients that make requests to servers. This is the traditional way to structure a client/server architecture.
- A web browser requesting a web page is an example of pull technology.
