How the internet works?
The internet and the worldwide web
The World Wide Web and the internet is not the same thing, and they are often confused with being the one and same. However, the internet existed long before the www (World Wide Web). The internet refers to the massive network of computers stretching all over the world. The word internet also found its origin through this, the word comes from the two words interconnected and network. Though we can all with each other through internet, all the computers are not connected to the one and same mega computer. For each network there are one or several computers that hold the information that is needed to access all the information. This arrangement is known as the client-server architecture.
Servers and clients:
The internet works on the basis that some computers act as ‘servers’. These computers offer services for other computers that are accessing or requesting information, these are known as ‘clients’. The term “server” may refer to both the hardware and software (the entire computer system) or just the software that performs the service. For example, Web server may refer to the Web server software in a computer that also runs other applications or it may refer to the computer system dedicated only to the Web server applicant. For example, a large Web site could have several dedicated Web servers or one very large Web server.
Internet Service Providers (ISPs):
An internet service provider is a business that offers Internet access service for both businesses and individuals. The main function of an ISP is to provide a link to the worldw...

...dors, partners, customers, or other businesses. An extranet can be viewed as part of company’s Intranet that is extended to users outside the company. This is almost the same as an intranet, when the intranet is protected with a password, and accessible from the outside, then it becomes an extranet.
Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
The Internet is a global network connecting millions of personal, institutional and company computers. The number of computers used by the internet is growing rapidly. The United States is connected with over 100 countries worldwide and linked together to exchange of data, news and opinions. The Internet is decentralized design. This means that there isn't just one computer that stores all of the information from the Internet. There are many independent host servers located throughout the US and the world that store the information made available to the global Internet community.
Networks can be categorized as following: a) Transmission media based networks like wired networks (communication takes place through wires) and wireless networks (communication takes place wirelessly). b) Network Size based networks like MAN, LAN and WAN. Wireless Networking is a technology in which two or more computers communicate with each other using standard network protocols and without using cables. The transmission
The internet consists of a global network of computers joined together to form one large interconnected network. It relies on Routers, Naps, ISPs, DNS and powerful servers to connect the network.
Some people may ask, “what exactly is the World Wide Web?” The Web has become so ubiquitous today that most people barely recognize what it actually is. A lot of people make the false assumption that the Web and the Internet are one and the same, when actually they are two very different things. The Internet connects millions of computers all across the world, forming a massive network. This network allows a computer to communicate information to any other device on the network as long as they are both connected to the internet. The Web on the other hand is a system of inter-linked documents that can be accessed over the Internet. This is all done through the use of a Web browser such as Internet Explorer or Mozilla Firefox. By using a Web browser, anyone can look at Web pages that contain a myriad of different things to view. A person can read books, watch videos, listen to music, and do an incredible amount more than just that over the Web (World Wide Web). The Web is an information-sharing model that is built on top of the Internet (Th...
A network is a set of communication devices that connected by wired or wireless to others
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
The internet is more popular today than it was years ago. As technology advances, the use of the internet grows yonder and is an amazing addition in our lives. The internet has been perhaps the most outstanding innovation in the field of communication in the history of humanity. The Internet is a global meeting place where people from all parts of the world can come together. It is a service available on the computer, through which anyone who has access to the Internet can receive. The internet is for a business owner, an employee, a student; it is for everyone.
... historical footnotes. Approximately 40 million people are connected to the Internet. More than $1 billion per year changes hands at Internet shopping malls, and Internet related companies like Netscape are the darlings of high-tech investors. Users in almost 150 countries around the world are now connected to the Internet and the number of computer hosts approaches 10 million (Howe). The Age of the Internet has arrived. Traffic on the Internet expands at a 341,634% annual growth rate (Pedroni). Within 30 years, the Internet has grown from a Cold War concept for controlling the tattered remains of a post-nuclear society to the Information Superhighway. Just as the railroads of the 19th century enabled the Machine Age, and revolutionized the society of the time, the Internet has taken us into the Information Age, and profoundly affects the world in which we live.
One of the most important technological advancement of all time is the development of the World Wide Web popularly known as “www” or W3. Beal, V. (n.d.) defines it as, “basically a system of Internet servers that support specially formatted documents. The documents are formatted in a markup language called HTML (HyperText Markup Language) that supports links to other documents, as well as graphics, audio, and video files. The World Wide Web (web servers) are able to communicate through the TCP/IP protocol which is a common language used by computers to communicate in the internet. The internet is just a networking infrastructure that enables different nodes (computer) to communicate with one another such as cables, satellite, telephone, fiber optic etc. Applications called Web browsers make it easy for people using computers and smart phones to access the World Wide Web. The advent of the internet and the World Wide Web has made it possible for people, businesses, companies and corporations to communicate at real time all over the world which was not possible before 1983.
What is the Internet? The Internet is the mechanism or matrix that connects networks around the world to each other and is generally referred to as the World Wide Web.
Internet is well known as the connectivity of two or more computers, or a connectivity of millions of computer around the world. They are linked to each other by many types of connectivity of networks such as telephone lines, cables or wireless and satellite connections.
Different devices which are interconnected with each other and communicate with each other, form an internet.
The Internet (Net) is a network of networks, connecting millions of computers together worldwide. It provides new ways of accessing, interacting, and connecting with people and content. It delivers packets of information similar to a postcard with a simple address on it, anywhere in the world. If you put the right address on a packet, and give it to any computer which is connected as part of the Net, each computer would figure out which cable to send it down next so that it would get to its destination.
"The Internet refers to the global information system that is logically linked together by a globally unique address space based on the Internet Protocol (IP); is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite; provides, uses, or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herin."
For many people the differences between the internet and the web are not clear and in many cases in day to day conversations these terms are used interchangeably to mean the same thing. Therefore to help understand the impact of the web, it would also be helpful to understand how it differs from the internet which this essay will first explain. We will then explore the difficulties in which internet users had before the web, the solutions and opportunities the web made available on its release to the world, and what effect this had on its growth. The web is a programmed framework linking stored information, data and web pages on the internet. The web uses the established infrastructure of the internet on which to operate on, in a similar way in which a car uses a road.
