what form of communication is sent from only a single sender to many receivers?
email
networks formed through social media change the way groups of people interact and communicate or stand with the votes. they "introduce substantial and pervasive changes to communication between organizations, communities, and individuals." these changes are the focus of the emerging fields of technoself studies. social media differ from paper-based media (e.g., magazines and newspapers) and traditional electronic media such as tv broadcasting, radio broadcasting in many ways, including quality, reach, frequency, interactivity, usability, immediacy, and performance. social media outlets operate in a dialogic transmission system (many sources to many receivers). this is in contrast to traditional media which operates under a mono-logic transmission model (one source to many receivers), such as a newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. some of the most popular social media websites, with over 100 million registered users, include facebook (and its associated facebook messenger), youtube, wechat, instagram, qq, qzone, weibo, twitter, tumblr, telegram, reddit, baidu tieba, linkedin, line, snapchat, pinterest, viber, mewe, and vk.

single sender to channels that receivers join to receive data.





















































alc does specify the session description needed by receivers before





















































they join a session, but the mechanisms by which receivers obtain





















































this required information is outside the scope of alc. an





















































application that uses alc may require that receivers report





















































statistics on their reception experience back to the sender, but the





















































mechanisms by which receivers report back statistics is outside the





















































scope of alc. in general, alc is designed to be a minimal protocol





















































instantiation that provides reliable content delivery without





















































unnecessary limitations to the scalability of the basic protocol.
