== Internet ==

The '''Internet''' is a global system of interconnected [[computer network]]s that use the Internet protocol suite ([[TCP/IP]]) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the [[World Wide Web]] (WWW), electronic mail, telephony, and file sharing.

The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, fault-tolerant communication via [[computer networks]]. This work led to the development of packet switching and the [[ARPANET]], which evolved into the modern Internet. The standardization of TCP/IP in 1982 and the introduction of the [[Domain Name System]] (DNS) in 1985 enabled the network to scale globally. The World Wide Web, invented by [[Tim Berners-Lee]] in 1989, made the Internet accessible to the general public and spurred explosive growth in the 1990s.

== Features ==

* '''Decentralized architecture''': No single entity controls the Internet; it relies on voluntary interconnection of independent networks.
* '''Packet switching''': Data is broken into packets, routed independently, and reassembled at the destination.
* '''Open standards''': Protocols like TCP/IP, HTTP, and SMTP are developed by open communities such as the [[Internet Engineering Task Force]] (IETF).
* '''Global reach''': Accessible in nearly every country, though censorship and connectivity disparities exist.
* '''Scalability''': Designed to accommodate an ever-growing number of devices and users.

== History ==

The concept of a "galactic network" was first proposed by [[J. C. R. Licklider]] in 1962. In 1969, the first ARPANET link was established between the University of California, Los Angeles and the Stanford Research Institute. Throughout the 1970s, [[Vint Cerf]] and [[Bob Kahn]] developed TCP/IP, which became the standard protocol in 1983. The launch of the [[World Wide Web]] in 1991 and the subsequent [[dot-com boom]] transformed the Internet into a commercial and social phenomenon. By the early 2000s, broadband and wireless access became widespread, and the rise of [[social media]], [[cloud computing]], and the [[Internet of Things]] (IoT) further expanded its role in daily life.
