Say it like this
The window you look at websites through. It goes and fetches the page, then shows it to you.
For the grown-up
A browser is a program that requests a page from a server, interprets the code that comes back, and draws the result on screen. Children often mistake the browser for the internet itself, in the same way people once mistook the television for the broadcast.
The easy mistake
Careful here. The browser is not where the website lives. It is more like a pair of binoculars than a bookshelf.
The full explanation
