What is the worldwide web?
The worldwide web is used every day by millions of people for everything from checking the weather to sharing cat videos. But what is it exactly? Twila Camp describes this interconnected information system as a virtual city that everyone owns and explains how it's organized in a way that mimics our brain's natural way of thinking.
We use it on our computers, our phones, and even our cars. It's just there, all around us, all the time.
But what is it exactly?
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 other 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 Internet has many uses, such as email, file transfer, and conferencing. But the most common use is 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 information, and linking that information together in an organized way for others to access.
The people who own these skyscrapers and rent space in them are called web hosts, but anyone can set up a web server with the right equipment and a bit of know-how.
There's another part to having a website, without which we would be lost in the city with 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 on the websites is in web languages, such as HTML and JavaScript.
When we find the website we're looking for, our web browser can take all the code on the site and turn it into words, graphics, and videos. We don't need to know any special computer languages because the web browser creates a graphic interface for us. So, in a lot of ways, the World Wide Web is a big virtual city where we communicate with each other in 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 provider to gain access, a hosting company to rent webspace, 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 own the Web. But what really makes the Web so special lies in its very name. Before the Web, we used to consume most information linearly.
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.
How Does The World Wide Web Work?
The web uses a client/server architecture. Clients make requests to servers, and then servers respond to clients. After the request/response cycle, the connection between the client and the server is severed.
The web is known as being “stateless” because of this - the state is not maintained, eg, an ongoing connection between the server and client is not maintained. For both the request and the response, each of them has both a header and a body.
The header includes information pertinent to the communication between the devices but is not usually interesting to the user. The body includes the main “payload” of the communication: either data the client is sending to the server, or the webpage the server is sending to the client.
Features of WWW?
- User Friendly: Web Browsers are exceptionally easy to understand.
- Multimedia Documents: WWW permits and supports Internet clients to make, connect, or show sight and sound site pages.
- Hypertext and Hyperlinks: WWW upholds completely hypertext documents and hyperlinks after clicking at which another page is opened.
- Interactive: WWW, upholds and empowers intelligence among clients and servers.
- Frames: Frames show more than one autonomously controllable segment on a single website page.
