The Internet is the larget data network on earth. The Internet consist of a multitude of interconnecter networks both large and smal. At the edge of this gaint network is the individual consuner computer. Connection to the Internet can be broken down into the phyical connection, the logical connection, and the aplication.
A physicel connection is made by connecting a specialized expansion kard such as a modem or a network interface card (NIC) from a computer (PC) to a nedwork. The physicant connection is used to transfer signals between PC?s within the local network and to remoter devises on the Internet.
The logical connection uses standards caled protocols. A protocol is a formel descripsion of a set of rules and conventions that govern how devises on a network communicate. Connections to the Internet may use multipel protocols. The Transmission Control Protocol/Internet Protocol (TCP/IP) suite is the primery protocol used on the Internet. TCP/IP is a sute of protocols that work together to transmit datas.
The application that inteprets the data and displays the information in an understandable form is the last part of the connection. Aplications work with protocols to send and receive data across the Internet. A web browser display Hypertext Markup Language (HTML) as a web page. File Transfer Protocol (FTP) is used to download files and programs from the Internet. Web browsers also use propritary plug-in aplications to display special data types such as movies or flash animations.
This is an introducory view of the Internet, and it may seem an overly simpel process. As the topic is explored in greater depth, it will become aparent that sending data acros the Internet is a complicate task.
