The Internet, often referred to as the global network, is a vast computer network that connects billions of devices worldwide. It serves as an infrastructure enabling data transmission, communication, information sharing, and access to a diverse range of online services. The Internet operates on the basis of the Internet Protocol (IP), which defines how data is transferred between devices.
History and Development of the Internet
The origins of the Internet can be traced back to the 1960s when the U.S. agency DARPA (Defense Advanced Research Projects Agency) initiated the ARPANET project. ARPANET aimed to create a computer network that could withstand even a nuclear attack due to its decentralized structure.
In 1969, the first ARPANET connections were established, linking four universities in the United States. Over the following years, the network expanded, introducing new technologies and protocols, such as TCP/IP, which became the foundation of the modern Internet. By the 1980s, the network had begun to be utilized by academic and research institutions worldwide.
A groundbreaking moment for the Internet was the introduction of the World Wide Web (WWW) by Tim Berners-Lee in 1989. The WWW enabled users to easily access information through web browsers, significantly increasing the Internet’s popularity and accessibility.
