Virtual reality is created by sophisticated computer technology. It gives us the impression of a real world. But virtual reality is not a real world. It's a world without physical reality. It can be seen, but it cannot be touched. Users, who want to view virtual reality wear helmets, which cover their eyes and ears. And the computer sends pictures and sounds through the helmet so you appear to be in a virtual world. So, when you move your head, the world moves with you.
'Virtual' is also used to describe the world of information and communication, which exists on the internet. Think of a library, for example. Instead of going to a real one, where you'd borrow books, you can get the information from a virtual place, the internet. You can browse through books and newspapers on the internet; you can also see video clips and pictures. You can find out about virtually anything on the internet these days. This is your world of virtual reality, too.
