The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.
The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web(WWW), electronic mail, telephony, and file sharing.
The Internet, sometimes called simply “the Net,” is a worldwide system of computer networks – a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 and was first known as the ARPANet.
The original aim was to create a network that would allow users of a research computer at one university to “talk to” research computers at other universities. A side benefit of ARPA Net’s design was that, because messages could be routed or rerouted in more than one direction, the network could continue to function even if parts of it were destroyed in the event of a military attack or other disaster.
The Internet’s Basic Information:
- The Internet and the WWW is not the same thing.
- Finding information on the Internet is achieved by using a search engine.
- Users browse web pages by following hyperlinks.
- The Internet is explored, which is more commonly referred to as surfing, using a browser.
- The Internet utilizes the TCP/IP protocol and is accessed using a computer modem, broadband, 3G, 4G, or network that is connected through an ISP.
- In the case of broadband, many computers and devices use Wi-Fi to connect to router that is connected to the ISP.
- The Internet is also used for communicating with others through social networks, online games, forums, chat, e-mails, IM, and VoIP.
- Files, pictures, songs, and video can be shared downloading and uploading.
