Broadcasting
From Wikipedia, a free encyclopedia written in simple English for easy reading.
In communications, such as radio and television, broadcasting means sending information electronically to a big audience. The information is sent through the air in radio waves or through a wire.
Broadcasting can also mean sending a message to many users on a computer network at the exact same time, or can even mean sending a message from one computer to many other computers, giving information about itself, such as its name and location.
Sending information to a small selected group is called narrowcasting.
