The Internet is a vast global network that connects millions of private, public, academic, business, and government networks, enabling communication and data exchange across the globe. Originating from research projects in the late 1960s, notably ARPANET, it has evolved into a complex infrastructure supporting various applications, including the World Wide Web, email, file sharing, and streaming services. It operates on a suite of protocols, with the Transmission Control Protocol (TCP) and Internet Protocol (IP) being fundamental for data transmission and addressing. Its impact on society is profound, transforming how people communicate, access information, conduct business, and interact socially. Today, the Internet is integral to daily life, influencing everything from education to entertainment and commerce.
