A URL is a lot like a house address. You can give someone a house address to let them know where to find a house or business they're looking for. You can give your browser a URL to let it know where to go to find the website you want to visit.
A URL often (but not always) starts with "http://" and then "www." A URL that starts with "https://" indicates that you're on a secure site. That means that if you enter personal information on that site, it will be encrypted before it's transmitted so that it cannot be intercepted by other people.
