Difference between "push technology" and "Pull Technology"

Push Technology is a mechanism established on the client server, that is, the server actively sends information to the client. Compared with the traditional pull (pull) technology, the main difference is that the push (push) technology is used by the server to actively send information to the client, while the pull (pull) Technology) the client actively requests information. The advantage of push technology lies in the initiative and timeliness of information.

Concepts of push-pull Technology
The so-called "push" Technology is opposite to the "pull" technology, that is, the server actively delivers information to the browser based on the preset file, rather than the real-time requirements of the user. The push technology is different from the pull information technology used for browser search. It is based on user needs, proactively send information of interest to the user's computer on a timely and purposeful basis. Just like broadcasting on a radio station, the "push" technology actively pushes the latest news and materials to customers, and users do not have to search online.
Before the advent of "push" technology, people often use browsers to search on the Internet, many users spend a lot of time and money to pull the information they need. On the other hand, the information publisher wants to send the information to the user's computer in a timely and active manner, instead of waiting for the user to pull. The "push" technology adopts a broadcast mode, which features a channel "broadcast" to allow online users to obtain the same information. Generally, there is a dedicated push software product (such as pointcast's pointcastnetwork) on the network server, which can be used to create and broadcast the information to be pushed out. On the client, the software installed on the PC is used to receive and display information uploaded from the network. When new information needs to be submitted, the "push" software will notify the user by sending an email, playing a sound, and displaying a message on the screen. The use of "push" technology can improve the timeliness and efficiency of users' information acquisition.
The "pull" Technology in network information refers to the active query of information on the network by the user purposefully. The user sends a request to the Web from the browser and obtains the required information from the web. As resources on the Internet become increasingly abundant, search engines have emerged to quickly and efficiently find useful information in the face of an Internet environment with massive amounts of information. Search engines are shortcuts to the vast ocean of information, so some people refer to them as "the door to the network ". Practice shows that the search engine is an effective auxiliary tool for pulling (querying) network information.
Application of Internet push-pull Technology
The push-pull technology has been widely used on the Internet, and many other technologies such as online information query and commercial website information publishing have adopted the push or pull technology. Now we will give a brief introduction from the following two aspects.
(1) Application of push-pull technology in email service
Currently, some websites have used push-pull technology for email services. For example, the famous Yahoo website uses push technology to manage emails. After a user registers a Yahoo mailbox, once the user enters the Yahoo homepage and logs on, there will be a prompt box to show you whether there are new emails in your mailbox, without entering your mailbox.
(2) Application of push-pull technology in some commercial websites
Some commercial websites, such as Dangdang online book houses, often send discount advertisements such as books and CDs to our email boxes. If you want to accept them, the information will be sent, this is the information transmission mode using the push technology. At the same time, if you go to the Dangdang Bookstore to search for the books you need, Dangdang records your query information, send related books to you on a regular basis based on your interests or notify you when the bibliography you are querying is not found, these are all customized services provided by Dangdang for you. This is an information service model in which users pull websites first and then push them.

Reducing users' browsing time on the Internet: Users no longer need to take the initiative to access the Internet.
Network path change: more and more active information and software providers
Channels and websites will be mutually dependent: channels will be used for message or advertisement transmission, but must be connected to the website to obtain the main content
The number of online ads is hard to measure: When a webpage sent to a user is not read, the website may be falsely reported and the number of ADS read.
(4) Cooperation between pull and push
Push some information to users in a timely manner, and then use the pull information to bring them back to interact with them. This rule is especially applicable when operating highly interactive online media.
The purpose of publishing a message is to attract audience members to the media website for further reading or interaction. If the push technology of the future cannot achieve this purpose, it is useless to use advanced technology.
