An Explanation of How the Internet Works

Have you ever thought how the Internet works? The research found here will help answer that question. The Internet is a complicated system. There are two main protocols that the Internet uses that allow you to transmit and there are certain procedures that allow you to receive information via the Internet. The Internet is very large and many things have to work correctly for information to get to your computer or to get from your computer to someone else's computer.

"The Internet is a network of networks," according to Quarterman and Salus and they state that it is the world's largest system of routes and connections. No one company or person controls the Internet (Quarterman & Salus). About 8,000 Internet Service Providers (ISPs) connect the matrix of hundreds of thousands of networks operated by many people in many different countries (Quarterman & Salus). The gateway to the Internet from your home computer is through an ISP. To get to the Internet through an ISP you have to have a modem dialup, ISDN (Integrated Services Digital Network), DSL (Digital Subscriber Loop), cable modem, wireless, or leased line. These methods provide a variety of speeds to connect the Internet, without one of these methods you will not be able to connect to the Internet.

Transmitting information using the Internet can be a little confusing to understand. As mentioned earlier, the Internet is a network of networks and there is a network protocol that allows computers electronically describe data (Scott's Newsletter). This protocol is called TCP/IP, Transmission Control Protocol/Internet Protocol. TCP/IP creates a packet-switched network that minimizes the chance of losing any data that is sent over the wires of the network (Scott's Newsletter). The first step in transmitting information using the Internet is when the Transmission Control Protocol breaks down each piece of data, like an email message, in to small chucks, which are called packets (Scott's Newsletter). These packets are wrapped in an electronic envelope with addresses for both the sender and recipient (Scott's Newsletter). The second step in transmitting information using the Internet is when the Internet Protocol figures out how the data is to get from point A to point B by passing through a series of routers, which is the same way regular mail passes through several post offices on its way to the recipient (Scott's Newsletter). Every router that receives the data will examine the destination addresses of the packets...
