Station identification is like a name tag for a radio or TV channel. Just like how you have a name to show who you are, TV and radio stations have a name that they show to let people know which station they are listening to or watching. They usually show it at certain times during programs, like at the start or end of a show, or during commercial breaks. It can be a picture, a logo, or even just saying their name out loud. This way, people know which channel they are listening to, and can easily find it again later if they want to listen or watch more.
