A channel is like a magic path that lets messages or things travel from one place to another. Think of it as a slide in a playground. When you climb up and slide down, you are moving from the top to the bottom. The slide helps you get there quickly and smoothly. In the same way, a channel helps messages or signals move from one point to another, like when you talk to your friend using a walkie-talkie.
Another way to think about a channel is like a river. Just as a river carries water from the mountains to the ocean, a channel carries information from one person to another. The water flows smoothly along the riverbanks, just like messages flow through a channel. If the river is blocked, the water can’t get through, just like if a channel is blocked, messages can’t be delivered.
Imagine a road where cars travel from one city to another. The road is the channel that allows cars to move. Without the road, the cars wouldn’t know where to go. Similarly, a channel helps guide messages or signals to their destination, making sure they reach the right place.
