Push technology allows other computers to send information that you have requested to your computer. The term refers to how computers gather information. When you search for material you want to see, you pull it to your computer.
Television is a real-world example of push technology.
You turn it on to view content that others send to you. You can make broad choices, such as the channel and whether you want to see a sitcom, news, or a movie, but the content is set and sent by others. You make yourself available to watch, and broadcasters push their selection of programming to you. Another way to think of the concept is in terms of your daily newspaper. The disadvantage is that only one version of the newspaper is published, so it contains a variety of information, some useful to you and some not.
