Final answer:
The Internet is based on key technologies including HTML for web page structure, URI/URL for resource identification, and HTTP for data transfer, which all contributed to its development and the advancement of Internet and Social Media.
Step-by-step explanation:
The three key technologies underlying the Internet, which made it the vast network it is today, include:
- HTML (Hypertext Markup Language): This is the formatting language that structures and presents content on the World Wide Web, allowing for the creation of web pages with text, images, and other multimedia elements.
- URI (Uniform Resource Identifier), also known as URL (Uniform Resource Locator): These are the addresses used to identify resources on the Internet, enabling users to locate websites, pages, and other digital assets.
- HTTP (Hypertext Transfer Protocol): This protocol enables the transmission of hypertext requests and information on the World Wide Web between client browsers and servers.
These technologies were spearheaded by Tim Berners-Lee and have been fundamental in the advancement of Internet and Social Media, transforming communication, commerce, and information sharing.
