Network Devices - YAML

Network devices are essential hardware devices for building, operating, and managing computer networks. They function at various layers of the OSI reference model, handling data transmission, routing, security enforcement, and other critical roles. From basic devices like hubs, switches, routers, and firewalls to auxiliary devices such as repeaters, bridges, gateways, and access points, appropriate equipment is selected based on network scale and purpose. In modern internet infrastructure and enterprise networks, these devices work together to provide stable communication environments.
