Push technologies, английский
Push is the automatic delivery of content, data or software to a desktop receiver or server receiver. here`s the problem that push technologies solve. you post new content on your web site but there`s no guarantee that anyone will care or even look for it. a related problem is tailoring interesting content so that it is easily located. libraries and stores have the ability to display materials for people in their store. how did they get them to come in. web sites have the same problem. a solution for both cases is push publishing where you send a message to your audience (students, employees, faculty, administrators) when you decide it is ready for distribution. a teacher might send a news article related to content to his students; ask them to read it and carry on a discussion about it in the internet classroom. distance learning administrators might send the new catalog directly to the student, or even a registration form for the next class in a sequence of classes. using push publishing, it`s possible to deliver to niche audiences and thus personalize the delivery to them. instead of only marking a document as new on the web page and waiting for someone to show up, an abstract of the document could be sent to the user. this is a broadcast model for the web and still one-way unless you provide a method for interaction as well as a reason. just pushing documents into student`s mailboxes is another form of junkmail unless it involves them in the process of learning. glossary/70 q
