Internet“,  we come to face to face this word many times in a day because this word becomes part of life.
But do you know what is meaning of Internet?. How internet word comes?.

Internet is Global system of interconnected computer network. It uses the Standard Internet Protocol Suite i.e.  TCP/IP to server billion users worldwide.”

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks.

Internet Addresses:
Because the Internet is a global network of computers each computer connected to the Internet must have a unique address. Internet addresses are in the form xxx.xxx.xxx.xxx where xxx must be a number from 0 – 255. This address is known as an IP address.
IP stands for Internet Protocol.

Owner of Internet:
After all question arise who is the owner of Internet? I goggling about this and found that  actually no one owns the Internet, and no single person or organization controls the Internet in its entirety. The Internet is more of a concept than an actual tangible entity, and it relies on a physical infrastructure that connects networks to other networks.  In other words there is lot of owner.

How Internet works?
The physical network that carries Internet traffic between different computer systems is the Internet backbone. In the early days of the Internet, ARPANET served as the system’s backbone.
Today, several large corporations provide the routers and cable that make up the Internet backbone. These companies are upstream Internet Service Providers (ISPs). That means that anyone who wants to access the Internet must ultimately work with these companies, which include:     UUNET,    Level 3,    Verizon,    AT&T,    Qwest,    Sprint,    IBM

To work better every where rule applied. Internet is among them. The Internet works because of a system of rules called protocols. By following these protocols, computers can send information across the network to other computers. If there were no protocols, then there would be no guarantee that the information sent from one computer could be understood by another, or that it’d even reach the right destination.

Then how Internet working Managed?
Again million dollar question then how Internet work? Above mentio There are several organizations that oversee the Internet’s infrastructure and protocols.
They are:
The Internet Society: A nonprofit organization that develops Internet standards, policies and education.
The Internet Engineering Task Force (IETF): An international organization with an open membership policy that has several working groups. Each working group concentrates on a specific topic, such as Internet security. Collectively, these working groups try to maintain the Internet’s architecture and stability.
The Internet Architecture Board (IAB): An IETF committee, the IAB’s mission is to oversee the design of Internet protocols and standards.
The Internet Corporation for Assigned Names and Numbers (ICANN): A private nonprofit corporation, ICANN manages the Internet’s Domain Name System (DNS). ICANN is responsible for making sure that every domain name links to the correct IP address.

The Internet: Computer Network Hierarchy
Every computer that is connected to the Internet is part of a network.  For example, you may use a modem and dial a local number to connect to an Internet Service Provider (ISP). At work, you may be part of a local area network (LAN), but you most likely still connect to the Internet using an ISP that your company has contracted with. When you connect to your ISP, you become part of their network. The ISP may then connect to a larger network and become part of their network. The Internet is simply a network of networks.

URL: Uniform Resource Locator

When you use the Web or send an e-mail message, you use a domain name to do it. For example, the Uniform Resource Locator (URL) “http://www.howstuffworks.com” contains the domain name howstuffworks.com. So does this e-mail address: example@howstuffworks.com. Every time you use a domain name, you use the Internet’s DNS servers to translate the human-readable domain name into the machine-readable IP address. Check out How Domain Name Servers Work for more in-depth information on DNS.

Ports and HTTP
Any server machine makes its services available using numbered ports — one for each service that is available on the server. For example, if a server machine is running a Web server and a file transfer protocol (FTP) server, the Web server would typically be available on port 80, and the FTP server would be available on port 21. Clients connect to a service at a specific IP address and on a specific port number.

Once a client has connected to a service on a particular port, it accesses the service using a specific protocol. Protocols are often text and simply describe how the client and server will have their conversation. Every Web server on the Internet conforms to the HyperText Transfer protocol (HTTP).

HTML
HTML stand for HyperText Markup Language.
HTML is the main markup language for creating web pages and other information that can be displayed in a web browser.

Web browser
A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web.

An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources.
