What is the Web?
The Web, often referred to as the World Wide Web (WWW), is a system of interlinked hypertext documents and resources that are accessed via the internet. It was invented by Tim Berners-Lee in 1989 and has revolutionized how we access and share information.
Key Components of the Web
1. Web Pages
Web pages are documents written in HTML (HyperText Markup Language) that can include text, images, videos, and links to other pages or media.
2. Web Browsers
Web browsers are software applications that retrieve, present, and traverse web resources. Examples include Google Chrome, Mozilla Firefox, and Safari.
3. URLs
A URL (Uniform Resource Locator) is the address used to access resources on the web. It specifies the location of a resource and the protocol used to retrieve it.
4. HTTP/HTTPS
HTTP (HyperText Transfer Protocol) is the protocol used to transfer data over the web. HTTPS adds a layer of security through encryption.
How the Web Works
When you type a URL into your browser, the browser sends an HTTP request to the web server hosting the page. The server responds by sending back the requested page, which the browser then renders on your screen. This process allows users to navigate from one page to another quickly and efficiently.
