In Streaming services, buffering is downloading certain amount of data before playing the video. Buffering usually occurs when there is problem of internet speed.
Video Streaming platforms are based on content on demand. Everyone wants to see different videos. Internet cables have their own bandwidth. So that’s why we see buffering on slow internet.
TV works on principle of broadcasting not the internet. The same to everyone at the same time even when TV is off. Our antenna catches those frequencies and we see different channels.
