Stream

Imagine you are sitting on the side of a small creek. The water in the creek is constantly moving down towards the bigger river. The moving water is called a stream. Just like the water in the creek, a stream is also a flow of water, but it's broader and might be deeper.

In the digital world, a stream is a continuous flow of data sent through the internet from one place to another. This information can be video, audio, text, or any other type of data.

When you watch a video on YouTube, you are receiving that video as a stream. The video is continuously coming to your device over the internet as you watch it, rather than downloading it all at once. This allows you the ability to immediately see the content without waiting for it to download completely.

Streams can also be live. Picture watching a parade on a livestream. The video you are watching is being recorded live and is immediately transmitted to you through the internet. As the parade continues down the street, the stream is sending live pictures to you through the internet.

In essence, a stream is like a steady flow of water or information that moves through a channel, it can be real-time and continuous, and it's accessible on-demand through the internet.
