Internet
The Internet is a computer network that connects computers worldwide.The Internet is made up of many smaller computer networks. These networks send and get messages using a standard Internet Protocol (IP). A protocol is like a language, that lets computers understand one another for all around the world. The Internet is used for many things such as e-mail, online chat, news services, forums and the World Wide Web (WWW). WWW the most command used in the internet which contains websites, web pages, blogs and wikis.
WWW ( world wide web )
The World Wide Web is that part of the Internet which is made up of web sites. Each Web site is made up of one or more web pages. The idea of the World Wide Web was put forward by a number of people, including Tim Berners-Lee (who has now been knighted in the United Kingdom!). It is only used to describe web pages that are connected to the Internet. For example web pages saved on a CD would not be considered to be part of the WWW. There is also a WWW organisation called the WWW Consortium that is dedicated to promoting web standards.

Router
A router is a wireless capable device that transmits a wireless signal. Wireless devices, such as laptops and tablets, use this signal to connect to each other and the Internet through a modem.
Wireless routers typically support one of two wireless standards, Wireless-G or Wireless-N. Wireless-N is newer and Comcast recommends that users with Blast! or Extreme Xfinity Internet service upgrade to a Wireless-N router. While you can access the Internet with all routers regardless of your speed tier, a Wireless-G router may prevent you from getting the maximum possible speeds.
