What is an internet and where can I get one?

The Internet is the World Wide Web and you connect to it by paying an Internet Service Provider. They will send you a router and cables that you connect to your compter through your phone socket and then you can access it.

Troll

it is a very rare and hard to come by thing. you cannot simply have an internet. you must have decades - no, scratch that. CENTURIES of training before being able to have an internet.

This has to be a troll, but incase it is not, you are on it now, there is no need to get it when you have it.

it cant be explained in few words

although it means world wide web

You are too late, there is only one and now everyone is sharing it so you can not have it.
