Internet: The Limitless Connected World
The History and Development of the Internet
The internet, a vast global network connecting billions of devices worldwide, has become an indispensable part of modern life. Its journey began in the 1960s with the ARPANET project of the US Department of Defense, initially aiming to create a secure and reliable communication system capable of functioning even if parts of the system were destroyed. From a small network for universities and research institutions, the internet has grown exponentially, transforming into a massive ecosystem with countless applications and services.
Core Technologies of the Internet
The internet operates on several core technologies, including: TCP/IP (Transmission Control Protocol/Internet Protocol), ensuring reliable data transmission between computers; DNS (Domain Name System), translating domain names into IP addresses, allowing us to easily access websites via domain names instead of complex IP addresses; and HTTP (Hypertext Transfer Protocol), the protocol enabling web browsers to load and display web pages.
Diverse Applications of the Internet
