The World Wide Web,where you're likely watching this video,is used by millions of people every dayfor everything fromchecking the weather,ordering food,and chatting with friendsto raising funds,sharing news,or starting revolutions. We use it from our computers, our phones, even our cars. It's just there,all around us, all the time. But what is it exactly?Well first of all, the World Wide Web is not the Internet,even though the terms are often used interchangeably. The Internet is simply the way computers connect to each otherin order to share information. When the Internet first emerged,computers actually made direct calls to each other. Today, networks are all around us,so computers can communicate seamlessly. The communication enabled through the Internethas many uses,such as email, file transfer, and conferencing. But the most common useis accessing the World Wide Web. Think of the Web as a bunch of skyscrapers,each representing a web server,a computer always connected to the Internet,specifically designed to store information and share it. When someone starts a website,they are renting a room in this skyscraper,filling it with informationand linking that information togetherin an organized way for others to access. The people who own these skyscrapersand rent space in themare called web hosts,but anyone can set up a web serverwith the right equipment a bit of know-how. There's another part to having a website,without which we would be lost in the citywith no way of finding what we need. This is the website address,which consists of domain names. Just like with a real life address,a website address lets you get where you want to go. The information stored in the websitesis in web languages,such as HTML and JavaScript. When we find the website we're looking for,our web browser is able to take all the code on the siteand turn it into words, graphics, and videos. We don't need to know any special computer languagesbecause the web browser creates a graphic interface for us. So, in a lot of ways,the World Wide Web is a big virtual citywhere we communicate with each otherin web languages,with browsers acting as our translators. And just like no one owns a city,no one owns the Web;it belongs to all of us. Anyone can move in and set up shop. We might have to pay an Internet service providerto gain access,a hosting company to rent web space,or a registrar to reserve our web address. Like utility companies in a city,these companies provide crucial services,but in the end,not even they own the Web. But what really makes the Web so speciallies in its very name. Prior to the Web,we used to consume most informationin a linear fashion. In a book or newspaper article,each sentence was read from beginning to end,page by page,in a straight line until you reached the end. But that isn't how our brains actually work. Each of our thoughts is linked to other thoughts,memories, and emotionsin a loose interconnected network, like a web. Tim Berners-Lee, the father of the World Wide Web,understood that we needed a way to organize informationthat mirrored this natural arrangement. And the Web accomplishes this through hyperlinks. By linking several pages within a websiteor even redirecting you to other websitesto expand on information or ideas immediatelyas you encounter them,hyperlinks allow the Webto operate along the same lines as our thought patterns. The Web is so much a part of our livesbecause in content and structure,it reflects both the wider societyand our individual minds. And it connects those mindsacross all boundaries,not only enthnicity, gender, and agebut even time and space.
