Communication Networks

Communication networks are interconnected systems of nodes and links designed to transmit, route, and receive information between two or more points, enabling coordinated exchange across local, regional, and global scales.

Overview

These systems operate through layered architectural models — most notably the OSI and TCP/IP frameworks — that decompose complex transmission tasks into discrete functional layers, from physical signal propagation through copper, fiber, or wireless media up to application-level protocols. Graph theory and combinatorial mathematics provide the analytical foundation for routing algorithms and network topology design, while information theory — pioneered by Claude Shannon — supplies the fundamental limits on data transmission rates and compression.

Why it matters

The emergence of packet-switched networks in the 1960s and their evolution into the global internet represented a paradigm shift comparable to the printing press, fundamentally reorganizing how knowledge is produced, distributed, and contested. Communication networks now constitute the foundational substrate upon which modern economies, governance structures, scientific collaboration, and social organization depend, enabling real-time coordination across continents and giving rise to distributed computing, cloud services, and the Internet of Things.
