What is a web address

When someone starts a website,they are renting a room in this skyscraper,filling it with information and linking that information together in an organized way for others to access.The people who own these skyscrapers and rent space in them are called web hosts,but anyone can set up a web server with the right equipment a bit of know-how.There's another part to having a website,without which we would be lost in the city with no way of finding what we need.This is the website address,which consists of domain names.
