Answer 1

A television channel is a terrestrial frequency or virtual number over which a television station or television network is distributed.
TV stations make their broadcasts by sending specially-encoded radio signals over the air.
Individual television stations are usually granted licenses by a government agency to use a particular portion of the radio spectrum (a channel) through which they send their signals.
Channels may be shared by many different television stations depending upon the location and service provider.
Analog television channels are typically 6, 7, or 8 MHz in bandwidth.
