A network switch is a scalable device that can increase available connection points on the network both wirelessly and cabled. A network switch acts as a central hub, allowing multiple devices to connect to a network and share resources. It increases the number of available Ethernet ports, which can be used for both wired connections (via Ethernet cables) and wireless connections (via access points connected to the switch). Additionally, there are wireless switches or controllers that specifically enhance wireless connectivity and manage access points in a scalable manner.
