Network

Networks connect devices: enabling data exchange across the globe.

A network links two or more computing devices (e.g., laptops, servers, IoT sensors) to share resources and exchange data. This interconnection can be physical (Ethernet cables, fiber optics) or wireless (Wi-Fi, 5G). Key examples include local area networks (LANs) connecting devices within a home or office, wide area networks (WANs) spanning geographic regions like the internet, and cloud networks facilitating distributed computing. Protocols (e.g., TCP/IP, HTTP) govern data transmission, ensuring reliable and ordered communication. The internet itself is the largest global network, a vast collection of interconnected networks.
