A router is an intelligent networking device that is mainly used to direct traffic between different networks. It makes use of IP addresses to determine the destination of data packets and ensures that they get to where they are supposed to go. It can also be used to filter traffic, block certain websites or ports, and provide security.
A hub is a simple networking device that can be used to connect devices in a network. It works by broadcasting data to all connected devices, and the device that requires the data will pick it up. Hubs are passive devices and can cause network congestion as they send data to all connected devices even if they don't need it.
A switch, on the other hand, is a more advanced networking device that can be used to connect devices in a network. Unlike hubs, switches are intelligent devices that can direct data to the device that needs it. They keep a record of MAC addresses of devices connected to it, and send data only to the device that needs it. This minimizes network congestion and is more efficient than hubs.
In conclusion, while routers, hubs and switches may perform the same basic function of connecting devices in a network, they do it differently and have different capabilities. Routers are intelligent devices that can direct traffic between different networks, hubs are passive devices that broadcast data to all connected devices, and switches are intelligent devices that direct data to the device that needs it.
