The network connecting devices, hub and switch, both assist in the connection of numerous devices. The hub transmits the signal to the port at the physical layer. The information is routed through a switch and sent over the network.
A networking device is referred to as a hub. It joins LAN segments and helps connect several devices to a single network. The physical layer of a hub is where it all happens, and it has a lot of ports. Any device that wants to connect to the internet can plug into one of these ports.
A networking device is a switch. It links and routes data between various devices on a same network. The Switch operates on a data connection layer. The data packet is transmitted over the network using the packet switching technology.
