A Network Component is a physical or virtualised hardware device — including routers, switches, firewalls, load balancers, and wireless access points — that forms part of telecommunications and computer network infrastructure, enabling connectivity, traffic routing, security enforcement, and data exchange between users, devices, and services. Together these components implement the layers of the OSI model and realise network topologies ranging from local area networks to wide-area internet backbones.
