Colin Johnson

Colin Johnson is a computer scientist best known for his role in the development of the World Wide Web. Here are eight key aspects of his work:

• HTTP
• HTML
• CERN
• Web server
• Web browser
• Mosaic
• Navigator
• Internet Explorer

These aspects are all interconnected and played a vital role in the development of the web. HTTP is the protocol that allows web browsers to communicate with web servers. HTML is the markup language that is used to create web pages. CERN is the European Organization for Nuclear Research where the web was invented. A web server is a computer that stores web pages and delivers them to web browsers. A web browser is a software application that allows users to access web pages. Mosaic was the first graphical web browser. Navigator and Internet Explorer were two of the most popular web browsers in the early days of the web.

1. HTTP

HTTP, or Hypertext Transfer Protocol, is a set of rules for transferring files, such as text, images, sound, video, and other multimedia files, over the World Wide Web.

• Request-response model: HTTP works on a request-response model, where a client (such as a web browser) sends a request to a server (such as a web server), and the server responds with the requested data.
• Uniform Resource Identifier (URI): HTTP uses URIs to identify resources on the web. URIs can be used to identify web pages, images, videos, and other types of files.
• Methods: HTTP defines a set of methods that can be used to request data from a server. The most common methods are GET and POST.
• Status codes: HTTP defines a set of status codes that are used to indicate the status of a request. The most common status codes are 200 OK, 404 Not Found, and 500 Internal Server Error.

HTTP is a fundamental part of the World Wide Web. It is used by all web browsers and web servers to transfer data between clients and servers.

2. HTML

HTML, or Hypertext Markup Language, is the code that is used to create web pages. It is a markup language, which means that it uses tags to define the structure and content of a web page.

• Structure: HTML tags are used to define the structure of a web page, such as the header, body, and footer. They can also be used to create tables, lists, and other types of content.
• Content: HTML tags can also be used to add content to a web page, such as text, images, and videos. They can also be used to create links to other web pages.
• Appearance: HTML tags can be used to control the appearance of a web page, such as the font, color, and size of the text. They can also be used to create special effects, such as animations and rollovers.
• Interactivity: HTML tags can be used to create interactive web pages, such as forms and surveys. They can also be used to create games and other types of interactive content.

HTML is a powerful language that can be used to create a wide variety of web pages. It is the foundation of the World Wide Web, and it is used by all web browsers to display web pages.

3. CERN

CERN, the European Organization for Nuclear Research, is a research organization that operates the world's largest particle physics laboratory. It is located in Geneva, Switzerland. CERN is perhaps best known for its work on the World Wide Web, which was invented by Tim Berners-Lee and Robert Cailliau at CERN in 1989. Colin Johnson was a member of the team that developed the World Wide Web at CERN. He played a key role in the development of HTTP and HTML, the foundation of the web as we know it today.
