The Internet started in the 1960’s and was name ARPAnet. It was originally a project of the U.S. Department of Defense to maintain communications in case of a possible nuclear strike. This network later on connected university mainframe computers along with scientists and the government in order to share research and stay connected with e-mail. During the 1980’s and 1990’s as computers were rising in popularity, users would get access to the Internet and today the Internet is a public web of millions of network devices.
What is the Internet? Well the millions of HTML pages on the Internet create a large part of it. The World Wide Web can be viewed by using a software called a web browser. Windows operating systems include a free browser called Internet Explorer. You can download many other free ones like Mozilla Firefox and Google Chrome.
The web is based on a language called HTTP (Hypertext Transfer Protocol). This language allows anyone to access a public web page.
The “Net” is not the same as the “Web”. Many people interchange the expression but it is not the same thing. The web is one part of the net. The Internet is made up of many subnetworks.
The biggest one is the World Wide Web and the other ones are email, instant messaging, P2P file sharing and FTP downloading.
There are other subnetworks other than the World Wide Wide included in the Internet..
Email is a subnetwork inside the Internet. Users exchange emails daily, along with file attachments. Email can provide a great way to have a paper trail of conversations. Be careful though, opening an email can download a virus to your computer or network. You boss wouldn't be too happy if the network was attacked.

These IM programs allow you to share audio, video, images and documents as attachments. You can use a web camera to video chat and join online conference calls.
File Transfer Protocol (FTP) is a network protocol used to transfer files from one host to another host over the Internet. This protocol can be used to publish web pages for web masters and it can be used to upload or download files from the Internet.
Peer-to-Peer Sharing (P2P) is based on the cooperative sharing of thousands of individual users. The users download a P2P program and start sharing their music files, video files and programs. The way it works is that each user shares little bits at a time. This is barely legal in the USA and can lead to users being sued by the Music and Movie industries.
At home and work, most people use the Internet for social networking. Social Networking is about meeting and maintaining communication with your friends, co-workers and family. Through a web page, you can gather your friends and exchange daily greetings and pictures. Some examples of popular social networking sites are:
