What is the Internet?
While most people use the words 'internet' and 'web' interchangeably (including on the Affilorama.com) they are actually different things. The internet is all the hardware and software that connects millions of computers to one another. The world wide web, or web is just one of the services available over this network of computers. Most of what we talk about in Internet 101 is actually the web, but we do also talk a bit about email, transferring files and communications systems that are also services available on the internet.
