A "channel" refers to a medium through which information, communication, or goods are transmitted. In media, it can mean a specific platform, like a television channel or a YouTube channel, where content is shared with an audience. Channels can also refer to pathways for distributing products, such as retail or online channels. In a more technical sense, a channel can describe a physical or virtual pathway for data transmission, such as a communication channel in networking. This includes various forms of connectivity, like radio frequencies or internet protocols, that enable devices to exchange information effectively.
