What is the Meaning & Definition of Broadcast
A broadcast is the distribution of audio or video to a particular audience. For communication and disciplines studying broadcasting, the broadcast is the most frequent Act of transmitting waves or signals of audio and video in various formats to an audience that may be local, regional, national, international and with different characteristics.
Broadcasting systems are many and varied. For example, there are broadcasting with national capacity systems that can transmit verbal messages in schools, hospitals and other public institutions. Other very common systems are less potent and broadcast from radio and TV stations to more or less small areas. The latter are the most frequently mentioned when referring to radio and TV programs that can be through relay towers, satellite and cable systems. Radio and TV media systems can cover areas as small as an Apple or hectare or so broad as entire continents. At the same time, the message up to different audiences through air (with antenna and receiver), cable (as with the TV cable), or the Internet.
The popularization of digital media and, more specifically, Internet, was a new form of broadcasting. Transmit through the Web is often much more easy, cheap and effective than using old traditional means of broadcasting. In addition, computer networks allow one much greater scope and global coverage. In the broadcasting over the Internet exists the multicasting (when the information arrives at multiple points), unicast (when only one) and anycast (when it comes to the nearest node).

Podcasting is the production of audio and/or video files for distribution by subscription online. The user that you want to listen to it receives a notice, download it and can transfer it to any multimedia device for access at any time.
