What is internet

What is the internet? The internet is the wider network that allows computer networks around the world run by companies, governments, universities and other organisations to talk to one another. The result is a mass of cables, computers, data centres, routers, servers, repeaters, satellites and wifi towers that allows digital information to travel around the world. It is that infrastructure that lets you order the weekly shop, share your life on Facebook, stream Outcast on Netflix, email your aunt in Wollongong and search the web for the world’s tiniest cat. How big is the internet? One measure is the amount of information that courses through it: about It takes some wiring up. Hundreds of thousands of miles of cables World wired web Photograph: TeleGeography/www.telegeography.com The cables range from the 80-mile Dublin to Anglesey connection to the 12,000-mile Asia-America Gateway, which links California to Singapore, Hong Kong and other places in Asia. Major cables serve a staggering number of people. In 2008, Last year, the chief of the British defence staff, Sir Stuart Peach, warned that Russia could pose a threat to international commerce and the internet if it chose to How much energy does the internet use? The Chinese telecoms firm Huawei estimates that the information and communications technology (ICT) industry could use 20% of the world’s electricity and release more than 5% of the world’s carbon emissions by 2025. The study’s author, Anders Andrae, said the com...

Constructing and maintaining the internet has been a monumental feat of ingenuity. What is the internet? The internet is a giant computer network, linking billions of machines together by underground and underwater fibre-optic cables.These cables run connect continents and islands, everywhere except Antarctica Each cable contains strands of glass that transmit data as pulses of light, according to the journal Science. Those strands are wrapped in layers of insulation and buried beneath the sea floor by ships carrying specialist ploughs. This helps to protect them from everything from corrosion to shark bites. The internet can connect us to others across the globe. (Image credit: Getty Images) When was the internet invented? It was originally created by the U.S. government during the Cold War. In 1958, President Eisenhower founded the Advanced Research Projects Agency ( ARPA) to give a boost to the country’s military technology, according to the Journal of Cyber Policy. Scientists and engineers developed a ne...

What Is the Internet? The Internet, sometimes called "the Net," for short, is a global network consisting of many networks which allow a user with a computer or similar device to interact with other computers. It's an autonomous, public, cooperative medium that's routinely accessed by millions of users to collect information, conduct transactions, or communicate with each other. The Internet connects millions of computers, mobile devices, servers, and websites around the world, letting users send and receive all manner of files (audio, text, video, image) and access resources such as apps and How the Internet Works To function, the Internet relies on our existing public telecommunication networks. The Internet consists of two major parts: the network protocols and the hardware. The hardware is the easy part; it includes smartphones, computers, or whatever other device users employ to access the Internet, all categorized as clients or endpoints. Hardware also includes the devices used to store and process the information, known as servers, which hold the websites we visit. Furthermore, hardware covers the transmission lines and other technology used to link everything together, such as cell phone towers, satellites, fiber optics or cables, and routers. The other part of the Internet, the protocols, covers Transmission Control Protocol/Internet Protocol (TCP/IP), a suite of protocols that allow devices to communicate with each other. These servers are connected to the Intern...

But you probably also want one that's fast, reliable and, of course, actually available in your area. Though pricing largely depends on the provider, speed potential, reliability and availability mostly fall on the network and connection type your ISP uses. That's why it's important to take into account a provider's connection type when So what's the difference between them all? This guide will walk you through the different types of internet connections that may be available in your area, how they work and what limitations you can expect from them. Connection types are listed in order of most to least recommended. Fiber internet: The best, but with limited availability Fiber-optic internet refers to a connection that comes to your home via long, thin strands -- or fibers -- of glass or plastic. ISPs send data along these fibers as light signals, resulting in speeds and reliability that are superior to other connection types. Fiber-o...

The Internet has revolutionized the computer and communications world like nothing before. The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. The Internet is at once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location. The Internet represents one of the most successful examples of the benefits of sustained investment and commitment to research and development of information infrastructure. Beginning with the early research in packet switching, the government, industry and academia have been partners in evolving and deploying this exciting new technology. Today, terms like “ This is intended to be a brief, necessarily cursory and incomplete history. Much material currently exists about the Internet, covering history, technology, and usage. A trip to almost any bookstore will find shelves of material written about the Internet. Learn more about how we are building a bigger, stronger Internet in 2021. In this paper, The Internet today is a widespread information infrastructure, the initial prototype of what is often called the National (or Global or Galactic) Information Infrastructure. Its history is complex and involves many aspects – technological, organizational, and community. And its influence reaches not only to the technical fields of comp...

Lesson 1: What is the Internet? Introduction The Internet is an increasingly important part of everyday life for people around the world. But if you've never used the Internet before, all of this new information might feel a bit confusing at first. Throughout this tutorial, we'll try to answer some basic questions you may have about the Internet and how it's used. When you're done, you'll have a good understanding of how the Internet works, how to connect to the Internet, and how to browse the Web. What is the Internet? The Internet is a global network of billions of computers and other electronic devices. With the Internet, it's possible to access almost any information, communicate with anyone else in the world, and do much more. You can do all of this by connecting a computer to the Internet, which is also called going online . When someone says a computer is online, it's just another way of saying it's connected to the Internet. What is the Web? The World Wide Web—usually called the Web for short—is a collection of different websites you can access through the Internet. A website is made up of related text, images, and other resources. Websites can resemble other forms of media—like newspaper articles or television programs—or they can be interactive in a way that's unique to computers. The purpose of a website can be almost anything: a news platform, an advertisement, an online library, a forum for sharing images, or an educational site like us! Once you are connected...

© 2010 HowStuffWorks.com Even though the Internet is still a young technology, it's hard to imagine life without it now. Every year, engineers create more devices to integrate with the Internet. This network of networks crisscrosses the globe and even extends into space. But what makes it work? To understand the Internet, it helps to look at it as a system with two main components. The first of those components is hardware. That includes everything from the cables that carry terabits of information every second to the computer sitting in front of you. Other types of hardware that support the Internet include These elements are connections. Some are end points -- the computer, smartphone or other device you're using to read this may count as one. We call those end points clients. Machines that store the information we seek on the Internet are servers. Other elements are nodes which serve as a connecting point along a route of traffic. And then there are the transmission lines which can be physical, as in the case of cables and fiber optics, or they can be wireless signals from satellites, cell phone or 4G towers, or radios. All of this hardware wouldn't create a network without the second component of the Internet: the protocols. Protocols are sets of rules that machines follow to complete tasks. Without a common set of protocols that all machines connected to the Internet must follow, communication between devices couldn't happen. The various machines would be unable to un...
