What is it? It is a decentralized set of interconnected communication networks that use the TCP/IP (Transmission Control Protocol/Internet Protocol) family of protocols, ensuring that the heterogeneous physical networks that compose it function as a single, worldwide logical network.
It is a large network of computers worldwide, which can exchange information with each other. They can communicate because they are linked through telephone connections, cable, waves or other types of technology and because they use the common TCP/IP language or protocol, rules that tell us how data has to travel through the network. The Internet is a worldwide network where computers are connected to it and use a common language.
A website is like a book, web pages are like the pages of the book, and hypertext is what formats paragraphs, images, and references (known as links) to other web pages.
The Internet has revolutionized computing and communications like no other invention. The invention of the telegraph, telephone, radio, and computer laid the foundation for this unprecedented integration of functionalities. The Internet is both a global broadcasting tool, a mechanism for disseminating information, and a means for collaboration and interaction between people and their computers, regardless of their geographical location.
