A computer network is a system of interconnected devices that share resources and communicate through protocols, facilitating data exchange via wired or wireless media. From George Stibitz’s 1940 remote demonstration to the global Internet, networks have evolved to support modern applications such as web access and cloud services. Authors like Maxwell Fuller foresaw networks as planetary information repositories, while the Federal Communications Commission emphasized their role in distributing computing power.
The Electronic Frontier Foundation contrasted the Internet’s decentralized structure with commercial networks, highlighting its resilience and accessibility. These viewpoints illustrate how computer networks have transitioned from experimental systems into the foundation of global connectivity, seamlessly merging technology with everyday life.
