Video server

A video server is like a special computer that stores and streams videos, sort of like how a TV plays shows or movies. A video server is like a big library that holds lots of videos, and when you want to watch one of those videos, it sends the video to your phone or computer while you watch it. It's sort of like how a pizza place makes pizzas and delivers them to your house when you order them. The video server also keeps track of which videos are available to watch and which ones people have already watched.
