Hubs

How do hubs work?

A hub is a network device that connects different network nodes, such as in an Ethernet network, in a star configuration. Their main task is to connect several computers and immediately transfer the data received. Hubs thanks to the star topology, allow users to extend the network structure in a very simple way. Hubs receive data and then send it in its entirety to all connected devices (hosts). All ports on a hub operate at the same speed and are in a collision domain (which includes all connected network devices). Unlike other network devices, the hub does not offer the option to control or exclude only individual receivers. This means that during transfer, all data packets are always forwarded to all computers.

Hubs

Industrial hubs are usually made of plastic, powered from an external power source and contain from 4 to 16 ports, that is, physical connections. Their maximum throughput is typically 10/100 Mbit per second. The devices have output channels that are equipped with an individual controller. Data from the master to the input channel is simultaneously forwarded to all output channels. The devices are adapted to industrial conditions, have EMC protection, can be mounted on a DIN rail and have a wide operating temperature range from -40°C to 85°C.
