Internet addresses work a lot like directions to someone's office building.
The computer name is like the street number for a building - every street can have a building with the same number, but a number can only be used once on each street. The domain name is like the name of the street and city in which the building is located. The path is a set of directions that are used once you find the building. They direct you to a specific item or area of the building. URL is an acronym for Uniform Resource Locator, a standard for naming resources on the Internet.
